Optimized systems save energy and costs
10
I Low “Life-Cycle-Costs” = “SAVE ENERGY”
I “SAVE ENERGY” = “SAVE MONEY” + “SAVE CO2-EMISSIONS”
As a result, companies, constructors and investors profi t. Therefore,
it is necessary to consider the following costs – especially for primary
energy, but also for maintenance. Then, it has been shown that high
quality technology and optimized system confi gurations contribute to
signifi cantly reduce the annual energy costs – and this only restriction
of the ventilation and air-conditioning functions.
technology are the basis for energy
effi cient ventilation and air-condi-
tioning.
Energetic non-optimized air-condi-
tioning is one of the main primary
energy consumers in buildings and,
therefore, cost driver. In order to
counter this cost explosion, bid ma-
nagement in accordance with low
“Life-Cycle-Costs” is necessary.
Competence and innovations deve-
lop through highly qualifi ed staff, as
well as target-oriented research and
development that fulfi ll the present
and future market requirements. For
this, the analysis of the “Life-Cycle-
Costs” and optimization also count
to that effect. The interdisciplinary
combination of control units, cooling
and heating pump technology with
the ventilation and air-conditioning

Unit design and construction in accordance with EN 1886 and VDI 6022
The housing frame construction con-
sists of 38 mm sendzimir galvanized
square section with a wall thickness
of 1.5 mm, connected by unit angles:
plastic angles for unit sizes 08 x 08 to
16 x 16, diecast aluminium angles for
sizes 20 x 16 to 49 x 32. This method
of construction makes sure that the
unit can be fully disassembled, because
welded joints are dispersed with.
All sealing material used is closed
porous and microbial inert.
Humidity-relevant components are
generally from corrosion resistant
material – exclusively stainless steel
– and contain a tank, which assures a
continuous and total removal of con-
densate. Commensurate with the highest
standards of the valid hygiene guide-
lines, all components are cleaned at
the works and packaged in foil for
transportation.
The functional units are easily
accessible on both sides for cleaning.
Therefore, all heat exchangers can be
cleaned to the core with low technical
and time effort.
All Filter, fan and humidifi er compo-
nents, from a unit height of 1.3 m, have
lighting and sight glasses. Thus, there
is an option for continuous inspection
without having to open the unit.
The mechanical stability conforms to
EN 1886. Thanks to the raster construc-
tion, it is a fl exible unit construction
with the virtue that it can be adapted
to the diverse designs.
The detachable cladding panels, 47 mm
thick and double-shelled, are lined in-
side for heat and noise insulation with
a non-fl ammable rock wool, in accord-
ance with DIN 4102 building material
Class A1, density of 55 kg /m3.
The panel of the inner and outer shell
is from 1 mm sendzimir galvanized
steel sheet. After manufacture, the
panel is completely powder-coated,
layer thickness min. 60 μm, RAL 7001.
Thus, there are no open cut edges.
Furthermore, there is no risk of corro-
sion. Cold and thermal bridges are
prevented from forming by a patented
thermal decoupling between the shells
of the panel.
1515
Unit components AT4 AT4 (Tropic) The housing inner surfaces fi t fl ush
with the frame. The inner surfaces
are completely smooth and have no
cut edges.
All joints and grooves in the unit are
resistant to disinfectant, sealed with
a microbial internal sealing material
and can be cleaned residue-free.
The base frame is galvanized and
powder-coated.
The door construction corresponds to
the housing panels (no cut edges, corro-
sion resistant), accessible units have
manual lever catches. Alternative is an
operation cover detachable at the side.

The modular AL-KO controller concept
not only convinces by its optimum
hardware components for HLK and
cooling applications, it also underlines
its high fl exibility by its free program-
mability of the functions, the I /O’s and
the operating structure. Because of the
selection options for the operating
language, commissioning and operation
abroad is made easier. Here, interna-
tional character sets are used.
All means are free for controller com-
munication and integration in existing
systems. The controller has two slots
for the optional communication plug-in
module, in which the RCC card, LON
card, EIB card or Quadcomm card can
be selectively integrated.

In many cases of application, cooling generation in the air-conditioning units presents a technically and economic-ally interesting alternative to central cooling. Over 20 years experience, our own development centre and highly qualified staff make AL-KO a strong partner for your projects.
3D-construction AL-KO Klim@Soft: air-handling- / air-conditioning-unit with
integrated cooling generation and energy recovery
I No costs for the hydraulic connection to a possible further detached central cooling unit.
I There are no distribution losses.I Modern methods of performance
control guarantee high partial load efficiency.
I By equipping the regrigeration system with heating pump control for the reversal of the refrigeration system, in many cases the residual heat portion of the exhaust air can be used very efficiently.
I The direct heat transfer through direct sublimation provides efficient dehumi-difying of air.
Many points speak for an integrated solution:I Less space requirement, through the
integration of a cooling unit in the air-conditioning unit.
I External heat exchange units or roof condensers for many air-conditioning applications are dispensed with, because the exhaust air can be used for the heat exchange.
I The complete solution from one source reduces your engineering effort and develops clear guaranteed limits.
3
The application of modern, highly efficient scroll-, reciprocating- and screw-type-compressors from a notable manufacturer, as well as the selection of the applicable partial load control for your application, guarantees the best performance data and optimum control.
The AL-KO solution spectrum: I Fully hermetic, in the application of the
optimized scroll compressor used in the air-conditioning technology
I Multi-compressor refrigeration systems for performance adjustment with up to three compressors per cooling circuit
I Up to two cooling circuits are manu-facturable
I Hot-gas bypass control adjusted to the multi-compressor refrigeration systems
I Digital scroll compressor for pulse-width modulated performance control
I Speed controlled reciprocating com-pressor
I Refrigerant R407C, R410a, R134a, according to the requirement.

Pre-dehumidification for a sorption dehumidifier using the condensationheat regenerationI Direct heat exchanger, transfers the heat
directly from the air to the evaporating of the cold media. No heat transfer from the cold media to a heat carrier (water or sole) required. The evapora-ting temperature can be applied ap- proximately 4 to 7 K higher. The surface temperatures necessary for dehumidification are generated more
efficiently.
I After the direct heat exchanger, an abso-lute humidity of 5 g / kg can be attained.
I An adjusted control of performance and exchange prevents icing and reduces the energy input in partial load mode.
I The waste heat of the cooling unit can be used, completely or in part, during the sorption process to preheat the regeneration airflow.

Main station Berlin – installation of the air-conditioning-units by helicopter.
The reconstruction of the Berlin main railway station was spectacular, because, above all, two office towers were tilted from both sides over the actual station to form the roof of the station.
The building work for the two office
towers represented the last section of completing the station. Both buildings are 46 metres high and, therefore, higher than the nearby Federal Chan-cellery, which is 36 metres height. Both construction frames overhang the East-West glass roof of the station like bridges, there-fore the designation “bow”.
Both bow constructions, totalling 12 floors, encompass approximately 50 000 square metres gross area. They are designed for office use. For the retention of occupant productivity in the large office area, the responsible
parties decided on total air-conditio-ning. Naturally, it was assumed that this air-conditioning can be operated with the least primary energy consumption.
10
Internal absorption in the unit rotary heat exchanger with humidity recovery
Because of the high percentage of glass area as facade of the bow construction, in summer, much of the thermal load must be dissipated by the air-conditio-ning units. For the selective promotion of this procedure, there are still some surface cooling elements and window convectors existing in the rooms.
parties involved in the construction and, not least, one of the great precedence‘s of a dismountable unit construction.
All units were accurately inscribed, so that they could be allocated easily at the installation site on the roof and helicop-ter for transportation. Installation was
However, the air-conditioning accom-plishes the majority of the remainder. A total of 6 AT4 air-conditioning-units were supplied, with integrated cooling, rotors for energy recovery and dehu-midification units. All air-conditioning-
units are tailored to the installation site because of the restricted space available.
On delivery of the central units, the foundations required and the retainer housing for the roof air-conditioning casings design were available.
The media pipelines for supplying the units in the roof casings were laid and the air connections and ducts in the building for connection of the units provided. Therefore, the missing air- conditioning units had to be transported by helicopter. Again a highlight for all
11
External absorption unit in the accessible roof casings
carried out immediately on the roof – 20 fitters were employed at this period
on each of the two bow constructions.
In total, the new air-conditioning-units accomplish a volume flow of approx.
170000 m³/h. For the application of office air-conditioning, 6 AT4 central
units were equipped with rotary heat exchangers. Because the supply air and exhaust air units are not separated spatially, rotors are, therefore, not very expedient, because humidity recovery can also be accomplished for. In the event of failure in summer, the heat recovery rate in the supply air is be- tween 71.2 % and 72.4 % and also analog the re-humidification rate be-
tween 42.5 % and 46.6 %. On winter days, the heat recovery rate is an average of between 70.7 % and 72.0 %, as well as a re-humidification rate of
75.4 % to 78.8 %. Therefore, not only can the primary heating energy be saved, but also the required energy supply to the humidification units is
reduced.

I process-oriented hygiene
solutions
Chemical and pharmaceutical deve-
lopment and production processes
place extremely high demands on the
involved air-handling and climate
systems with regard to safety, preci-
sion, reliability, reproducibility,
and durability.
In chemical and pharmaceutical pro-
cesses, safety is the top priority. Whether
in handling with aggressive and explo-
sive substances or when handling toxic
and environmentally harmful, natural
or genetically modifi ed biomaterials, it
is always valid to use controlled supply
and exhaust via suitable air-handling-
systems.
The demands for material purity on the
one hand and economy on the other place
extremely high demands on the precis-
ion and reliability of modern chemical
and pharmaceutical production pro-
cesses. The air-handling-systems used
must, among other things, assure
the thermodynamic, air-handling, and
climatic environmental conditions re-
quired for this and must therefore fulfi l
the same precision and reliability re-
quirements as the actual systems
themselves.
Air-handling and climate systems re-
present an essential component of the
primary development and production
apparatuses in the chemical and phar-
maceutical process chain. From a quality
management standpoint, these systems
are therefore subject to the same de-
mands as for the actual development
and production plants themselves. The
requirement for “best practice perfor-
mance” therefore sets the quality bar
for reliability and reproducibility, which
must also apply to the air-handling-
systems used.
In addition to the actual process
sequences, achieving the necessary
level of economy and product quality
requires all apparatuses and systems to
be of extremely high durability and
intrinsic value. Particularly in the fi eld
of chemical and pharmaceutical produc-
tion, this requires the use of the best
materials as well as special, adapted,
and optimised structural, global, and
detailed solutions.
AL-KO Air-Technology has been involved
for decades in the development and
production of air-handling-units that
fulfi l all of the requirements mentioned
above of chemical and pharmaceutical
development and production. The special
material adaptations, structural features,
modular design, and optimised energy
consumption of the AT4 and AT6 unit
series assure a client-specifi c applica-
tion for every process situation.

AIR-HANDLING-UNIT AT4 COMPLIANT WITH EU GUIDELINE ATEX 95
SAFETY CERTIFIED QUALITY
AIR-HANDLING-UNITS
ATEX 95 unit categories
According to the ATEX guideline (94 / 9 /
EG), units are grouped into categories
for use in the corresponding zones.
There are three different unit categories
for the unit group II, which correspond
to the different zones. This makes it
possible to associate explosion-proof
products with operational Ex zones.
Category 1 includes units for zones 0
and 20 (very high degree of safety).
AT4-classifi cation
Category 2 includes units that are struc-
turally designed so that they can be
operated in compliance with the para-
meters furnished by the manufacturer
and assure a high degree of safety. Units
of this category can, upon approval, be
operated in zones 1 and 21.
Category 3 includes units that are struc-
turally designed so that they can be
operated in compliance with the para-
meters furnished by the manufacturer
and assure a normal degree of safety.
Units of this category can, upon appro-
val, be operated in zones 2 and 22. DIN
EN 50281-1-2 differentiates between
conductive and nonconductive dust.
When there is conductive dust in zone
22, equipment from category 2 D must
be used.

HIGHEST RELIABILITY FOR REDUCED INVESTMENT COSTS FOR BUILDING SERVICES
VENTILATION AND AIR-CONDITIONING-UNITS
2
Only someone who can breathe,has a chance of survival
In most cases, the victims of fi re
in buildings suffocate before the
temperature for combustion has
been reached. More than 95 % of
all fatalities and more than 70 %
of all damage to property and in-
surance loss by fi re are a result
of smoke.
In building fi res, it is long-standing
knowledge that smoke represents
the greatest source of danger. Only
when the people affected have air
to breathe can they orientate them-
selves and get to safety.
Origin of fi re
Time
SMOKE TEMPERA-TURE
For example, 10 kg of fl ammable
foam rubber generates 25 000 m3
of fumes in only one hour. In this
case, the source of fi re is only as
big as an armchair.
3
As part of a building, air-conditioning
plants must generally conform to the
fi re protection requirements. Air-con-
ditioning plants that are exclusively
used for ventilation must be switched
off in the event of a fi re.
Air-conditioning-units can be used for
smoke discharge and/or for supplying
air in the event of a fi re in the areas of
buildings with a sprinkler system.
Here, components that are checked for
temperature resistant must be used, as
well as checking for further ancillary
conditions.
Smoke discharge in areas with a sprinkler system
Temperature of fumes, 100 °C to 300 °C
Smoke discharge in the event of fi re, using ventilation appliances
I The smoke discharge concept is designed for smoke discharge up to a max. of 300 °C over a maximum period of two hours (for areas with sprinkler system).
I The unit design to be used, AT4-E, is equipped accordingly and has been tested under these conditions.
I All integrated components have a national technical approval.I In particular cases, an approval from the competent authority is required.I The ductwork for the smoke discharge must be checked. Outside of the area on fi re,
exhaust air ducts from L90 must be designed.I The ventilation appliance must be installed outside of the area on fi re. The room must not
conform to further F90 specifi cations.I Smoke discharge and ventilation can be carried out by a 2-stage fan. Currently, the use of a
frequency converter is not permitted.
In all cases, the use of an air-conditioning unit with a smoke discharge function must be clarifi ed with the appropriate authorization body, because use of air-conditioning-units for the assistance of smoke discharge is not explicitly defi ned in the building laws.

Smoke discharge solutions with AT4 ventilation appliances
Case 1
Smoke discharge by the
exhaust duct system
The ventilation appliance has a supply
air and exhaust air fan as standard.
In the event of smoke discharge, the
supply air fan is switched off. The air
circulation channel is closed by a fi re
protection valve. The two-stage exhaust
fan sucks the fumes from the exhaust
duct and conveys them outside, through
the exhaust air duct.
Case 2
Smoke discharge by the
supply air duct system
Because of spatial circumstances, the
supply air duct system is often more
suitable for fume extraction. In this
case, in the smoke discharge mode of
operation, the exhaust air duct, as well
as all components of the air supply unit,
are closed from the exhaust air channel
using smoke protection valves.

Case 3
Smoke discharge by
an exhaust air unit
Smoke discharge by an exhaust air unit
is possible, providing that the fl ammable
components in the exhaust air unit can
be circumvented through a bypass.
Case 4
Ventilation appliance with
parallel smoke discharge fans
The discharge of smoke is carried out
through additional smoke discharge
fans, connected laterally directly on
the supply air outlet and / or on the
exhaust air inlet. The complete ventila-
tion unit is shut off from the smoke
discharge duct by smoke protection
valves, so that all fl ammable compo-
nents can be bypassed.

AT4-T AIR-HANDLINGIN TROPICAL DESIGN
AIR-HANDLING-UNITS
AT4-T air-handlingin tropical design
Air-handling-units are exposed
to different environmental- and
operating conditions which require
highest demands on the characteri-
stics of the construction.
Specifi cations for AT4-T
So, the thermal performance of the air-
handling-unit casing is a most important
part. Heat losses and thermal bridges,
just as appearances of condensate and
infi ltrations caused by design of air-
handling-unit casings, can lead to loss
of energy or damages which are well-
known from various problems in the con-
struction business. AL-KO Air-Techno-
logy has taken care of this subjects and
therefore designed a product which is
fulfi lling all requests for state-of-the-
art air-handling-unit constructions. To
meet this high requirements as quality
and functionality also in future, AL-KO
Air-Technology has set a signal with the
new casing construction AT4-T. The use
of most modern materials in combina-
tion with an optimized structure work
allowes no thermal bridges even under
extreme operating conditions.
Unit construction totally smooth inner
surface without edges, joints and grooves.

In spite of this thermal optimisation
of the casing, the main characteristic

CLIMATISATION ANDDEHUMIDIFICATION OFINDOOR SWIMMING HALLS
Cutting-edge technology in swimming hall climatisation and dehumidifi cation
In indoor swimming pools, especially
when open to the public, there is a high
level of humidity. People fi nd humidity
levels above the sultry limit extremely
unpleasant, considerable damage can
occur to the structure. The humidity
released by the water can only be dis-
charged by the air. Because of the areal
restrictions of indoor pools, as well as
the necessary areal purging with dehu-
midifi ed air, only mechanical ventilation
can be used to achieve this. Modern air-
conditioning-units, specially designed
for the special requirements of indoor
pools, dehumidify, heat and ventilate
every type of indoor pool and their
adjoining rooms.
Economic ventilation and
dehumidifi cation
Through the mixing of extracted air –
in the heat recovery unit already
predehumidifi ed – and fresh air (from
out-side), it is very possible to prepare
optimum dehumidifi cation of condi-
tioned mixed air economically on the
basis of the acknowledged ranges of
application in the VDI 2089.
The mixed air is heated by the heat re-
covery and subsequently heated to the
required operating temperature using
a pump-hot-water heater or a highly
effi cient heating pump.
We are taking care of economical
operation for optimal humidity and
therefor the very best indoor air
climate in swimming halls.

THE LUXURY CLASS OF MARINE AIR-HANDLING-UNITS
AIR-HANDLING-UNITS AT4
The modular construction of AL-KO
AT4 air-handling-units offers the
highest fl exibility regarding unit
dimensions.
AT4 marine air-handling-units can be
produced in more than 25 standard
unit sizes. Especially in the sector of
air treatment for marine applications
with its extreme air-conditions and
corrosive sea air as well as the static
demands of the shipbuilding the ap-
proven AT4 construction satisfi es the
highest demands. One of the biggest
advantages is the material suitability.
Standard AL-KO AT4 units are powder-
coated and therefore perfectly pro-
tected against corrosion.
The application variety of AT4 marine
air-handling-units ranges from contai-
ner ships to cruising vessels and even
up to luxury yachts.
AL-KO has long-time experiences for
planning, production and engineering if
it comes to marine applications.
You are in good hands with AL-KO for
all kinds of marine air-handling-units.
The special advantages of the AL-KO AT4 marine air-handling-units
Quality of great value
HIGH-TECH-COMPONENTS
Hygiene construction for easy cleanability
The inner surfaces of the units are
completely smooth, which plays an
important role for the cleaning and
servicing of the units.
The AT4 unit type serie is predestined
for the operation in the hygienic area.
Low heat losses as well as high sound
insulation with incombustible materials
are achieved by the constructions of
our 47 mm thick panels.
The AL-KO AT4 typifi es an air-handling-
unit with fl exible materials in inner and
outer walls. With our special construc-
tion different material confi gurations are
possible. Every air-handling-unit can be
individually designed by the use of
Salty air and extreme climate conditions require an adaptable unit concept
panels and installations in galvanized
steel, powder coating (standard color
RAL 7001, other color on demand),
and stainless steel V2A (SS304) as
well as V4A (SS316L).
Space-saving installation
The AT4 air-handling-unit system can
be delivered in divided construction,
so that the placement and on-site
assembly can be carried out very
easy. Besides this, the full functiona-
lity is maintained. Additionally,
costs are saved due to the fact that
no expensive openings are necessary
for the insertion of the units.
For every application in the marine air-
conditioning, we will fi nd the right so-
lution just for you. This also includes
planning and production of the units
with the corresponding functional units.
Today the choice and planning of the
suitable energy recovery system is
most important for an energy-saving
operation of air-handling-units.
Our unit range encloses air-fl ows from
1 000 m³/h up to 100 000 m³/h.
Ship builders and installation com-
panies all over the world can count
on our air-handling-units and on our
engineering. AL-KO belongs to the in-
ternationally leading manufacturers of
air-handling-units for shipbuilding.
Our adaptable air-handling-unit concept offers fi tted solutions including high energy effi ciency.

ENERGY-EFFICIENT CLIMATISATIONAND DEHUMIDIFICATION
Compared to other techniques, the AL-KO
air conditioning technology with rotary
dehumidifi cation reduces the yearly energy
costs. A signifi cantly smaller dimensioned
cooling unit is integrated in the AHU unit
instead of a standard cooling coil. Additio-
nally a rotary energy recovery / thermal
wheel is included.
Thereby an extensive pre-dehumidifi cation
of the supply air will be ensured. The
required dehumidifi cation performance
is considerably lower than other systems
without recovery of the cooling energy
from the extract air.

Compare Investment Costs
The yearly energy costs and operating costs of an AL-KO HVAC
with the rotary dehumidifi cation „Humid-off®“ are at least
40 % lower than the ordinary systems for dehumidifi cation and
climatisation due to the smaller dimensioned cooling unit (Life-
Cycle-Costs).
In addition the portion of investment costs of this “ventilation and
air conditioning” is lower!
Life-Cycle-Costs
Low Investment Costs and Operating Costs
The supply air is cooled and dehumidifi ed with the cooling
recovery out of the exhaust air by using a sorptive coated
rotary heat exchanger. This is how the necessary cooling
supply can be realized with a small integrated cooling machine
or a distance cooling connection with low quantities in order
to reach the desired interior air state.

The accuracy attained here greatly ex-
ceeded the accuracy of measurement
on building sites².
The test chamber is monitored by the
TÜV Süd (Technical Inspection Authority,
south). The injection nozzles, used for
air-fl ow volume measurement, attain
an accuracy of +/- 1.5 %!
As test documentation, the customer
receives the measured unit characteris-
tics.

EASYAIR®
Unit execution and options
eneV 2009 (energy saving regulation)
EASYAIR® air handling units are manufactured and designed according
to the European Guideline EnEV 2009. It must be also highlighted that due to
the high efficiency of the heat recovery
(80 – 90 %), due to the most energy
efficient motor technology for the fans
and due to the intelligent control of all
components all EASYAIR® air handling units are actually better than
the todays requirements of the EnEV
2009.
VDi 6022 (hygienic requirements)
All EASYAIR® air handling units are manufactured and designed ac-
cording to the European Guideline VDI
6022. The casings of all EASYAIR® air handling units are powder-coated
on both sides. Other components are made from galvanized steel. All
EASYAIR® air handling units warrantees full access for service and maintenance in accordance with the VDI 6022.
heat recovery
Selection can be done between ro- tary or plate heat exchanger. Rotary
heat exchangers are preferred when recirculating air operation is
possible. To prevent cross-flow-
contamination between supply and
exhaust air, the use of plate heat
exchangers is recommended.
i ro- = with rotary heat exchanger
i pL- = with plate heat exchanger
i RO-04-R-X = Casing in non-split execution
i RO-04-R-T = Casing in split execution
i RO-04-R-W = Casing for outdoor installation
i RO-04-R-W = Casing for outdoor installation with an
intake and exhaust hood
filter classes
As standard, the EASYAIR® is supplied with high efficient air filters. In the supply air there is a F7 and in the
exhaust air there is a F5 filter installed.
The quality of the filters are according
to VDI 6022.
i RO-04-R-X-75 = Supply air f7, exhaust air f5
i RO-04-R-X-e75 = Supply air f7, exhaust air f5 incl.
spare filters
Dampers
The EASYAIR® is supplied with internal, air tight dampers (tightness
class 2). One damper at the air inlet
for outside air and one damper at the
air outlet for exhaust air. Thus, no
additional dampers are required to be
installed in most of the applications
in the supply and/or exhaust air duct.
The internal dampers are supplied
with actuators. A further advantage:
No additionally thermal insulation is
required. As an alternative, you can get
the EASYAIR® also without these
internal dampers.
i RO-04-R-X-75-mK = with internal dampers
i RO-04-R-X-75-oK = without internal dampers
unit sizes
Both types of heat recovery units are
available in various sizes. For each size,
with their optimized air volumes, please
refer to page 4 and 5.
i RO-04 = Size 04, for air volume
between 2.000 to 5.100 m³/h.
Sample for selection is done by
choosing an EASYAIR® with rotary
heat exchanger (RO-), size 04 (RO-04).
service side
Of course, you can easily select the
service side of the EASYAIR®.
Doors ensure good access for main-
tenance and service works. The
indication for the service side is always
based on the direction of the supply air.
The service side in supply air direction
right conforms to the demonstration
given on page 4 and 5.
i RO-04-r = Service side in supply air
direction righti RO-04-L = Service side in supply air
direction left
split and outdoor execution
From unit size 04, there is the possibility
to order EASYAIR® in a split execu-
tion. Thus, the air handling unit can be
installed very easily, even e.g. when the
access openings are limited. Please refer
to the dimension table on page 4 and 5.
All EASYAIR® units can be ordered
for outdoor installation as a weather-
proof unit. Weatherproof units are only
available in one part and have a weather- proof roof with drip tray. As an option,
weatherproof units are available with an
intake and exhaust hood.
7
Duct connections
For all EASYAIR® air handling units acoustically isolated duct connections
are available that utilize the complete
open cross-section of the unit. Using
these duct connections, the duct of
the EASYAIR® air handling unit is well isolated against the transmission
of sound and vibration. External noise
transmission is substantially reduced.
i RO-04-R-X-75-MK-Z = with duct
connections
i RO-04-R-X-75-MK-o = without duct connections
control
The EASYAIR® air handling units have an integrated controller as
standard. All internal components of the
units are prewired and ready for use.
An exhaust air temperature sensor in
combination with heating and / cooling
coil warrantees a constant supply air
temperature. Many energy efficient
control functions are integrated in the
software and easy to extend by using
additional options.
The available options are as follows:
i -ra = Room sensor
i -DK = Constant pressure control
i -VK = Constant air volume control
i - aQ = AL-KO air quality control in the
exhaust duct
i -rc = Remote control with 10 m cable
i -BL = Bus module LON
i -Bm = Bus module Modbus
i -BB = Bus module Bacnet/Ethernet
i -cX = Without control
note: The measurement values (data
points) and communication commands
are permanently configured and are
independent of the Bus module and
cannot be changed.
Without control: All field devices are
wired for easy connection to an on-site
controller, on a terminal strip. There-
fore, there is no wiring required in the
unit on-site. Furthermore, a main switch
for all-phase switching is installed on
the unit. The power fuse is not included
in the design and must be supplied on
site. For EASYAIR® units with rotary
heat exchanger, the connections of the
drive motor are supplied through the ter- minal strip. The unit has no integrated
rotor control. Only a rotor drive with
integrated speed set point input is pro- vided. The operation is additionally
monitored using a potential-free (closing)
contact fed through the terminal strip.
The AL-KO air quality controller
AIRQUALITIZER® is supervising
the quality of the exhaust air. If this
sensor detects odours or emissions in
the exhaust air (VOC = Volatile Organic
Compounds), the quantity of air is
increased and, within a short period of time, you will have a good quality of air in the room again. If there are e.g. only a few people in the room, the
AIRQUALITIZER® can reduce
the air volume (partial load operation)
and you save operating costs. By using
this intelligent air flow management,
only the required air flow is conveyed.
electric air heater (option)
An electric air heater can be connected
to each EASYAIR® (up to unit size
-06). This electric air heater is directly
installed on the air outlet and is
available with a rating between 3 and 15 kW. During a few days with low out-
side air temperatures, you can slightly
increase the room temperature till
desired temperature has been reached.
i -eLe = with electric air heater
hot water air heater (option)
Each EASYAIR® can be supplied
with a hot water air heater. This heater
is directly installed at the air outlet.
Here, you also have the simple option
to slightly increase the room temper-
ature during cold weather conditions
and to provide a comfortable room
temperature. Heater includes frost
protection.
i -WWe = with hot water air heater
(LPHW)
heater/cooler module (option)
For demanding applications, you can
also connect an additional module to
the EASYAIR® (refer to page 4
and 5). In this module you will find all
accessory that you require for a wide
range of application for cooling and
heating. The module is equipped with a drip separator.

“ MILE-STONES” IN REDUCTION OF “ LIFE-CYCLE-COSTS”
AIR-HANDLING-UNITS AT4 | SAVE ENERGY
PREISENTWICKLUNG VON ÖL
Shortages of fossil fuels and the political will
to reduce C02 emissions in accordance with
Agenda 21 are leading to a dramatic increase in
operating costs of energy-intensive systems.

PRICE TREND OF OIL
Foreword
system confi gurations have been shown
to contribute to a signifi cant reduction
in the annual energy costs – and this
without limiting the ventilation and air-
conditioning functions.
Thus a low investment price or low op-
erating costs alone are not the decisive
factor that determines the economic
effi ciency of air-handling-systems. In
addition to unlimited and proper func-
tion of the units and systems, the “Life-
Cycle-Costs” (LCC) – a sum of all costs
from installation to decommissioning –
are the only criteria to measure the
economic effi ciency of ventilation and
air conditioning systems.
Come see the kind of economic and
ecological potential that can open up in
buildings. Learn how you can harness
this potential for yourself.
Sincerely yours,
Prof. Dr.-Ing. Michael Haibel
“You get what you pay for.” This simple
bit of folk wisdom that‘s so easy to say
can turn into bitter truth rather quickly
for just about any investment in which
the follow-up costs are not taken into
account. This rude awakening can be
even worse if the follow-up costs are the
same or even higher than the original
investment costs.
This is especially true for ventilation and
air-conditioning-systems in buildings.
The annual operating costs, i.e. the costs
for energy, maintenance, and service of
the systems can end up being as high
as the one-time investment costs. But
high-quality technology and optimized

Air-handling-systems with low investment costs frequently resultin much higher operating costs than necessary!

systems and furthermore R&D consultant of AL-KO Air-Technology
Factor analysis
The primary goal in conceiving buildings
that last is to signifi cantly reduce energy
requirements and to create a comfortable
interior climate. The primary basis for
sustainable ventilation and air-condi-
tioning concepts is the climatic data of
the location. Creating a comfortable and
productive interior climate requires the
logical implementation of thermodyna-
mic function units. The goal of the
planning must be the energy effi cient
implementation of these requirements,
taking into account the “Life-Cycle-Costs”
(LCC) of the system. Air-conditioning
that is not energy-optimized will be the
cost factor of the future.
In order to counteract this cost explo-
sion, it is necessary to invite bids for
“Life-Cycle-Costs”.
1. Climate data of your location
The starting point for optimum design
of air-handling-systems is the correct
climate data of the location. The dimen-
sions are selected based on the recorded
outside air temperatures, as set forth in
DIN 4710/TRY
4
2. Healthy and comfortable
Maximum productivity can only be
achieved in a comfortable environment
at optimum room temperatures between
21 °C and 26 °C, in combination with
an interior humidity of 40 % to 60 %.
The main requirement for the building
air-conditioning, therefore, is to create
a healthy, comfortable interior climate
with the appropriate air quality in order
to increase motivation and productivity
in the work force.

3. Requirements of the air-handling-
system
Depending on their location, air-handling-
systems must reliably perform a variety
of functions such as cleaning, heating,
cooling, ventilating, humidifying, de-
humidifying, and combinations of these.
For economically meaningful planning,
it is imperative to precisely defi ne the
array of functions of the air-handling-
system and the air quality it will be
required to achieve.
4. Important – taking into account the
energy quantities of the air-hand-
ling-system
Productivity-enhancing air-conditioning
does not have to be expensive. When it
comes to energy and economy, most
conventional systems currently in use
require new capital investment.
When planning an air-handling-system
according to the “Life-Cycle-Costs” prin-
ciple, more emphasis is thus placed on
the electrical connected load of the
ventilator and on the effi ciency of the
heat and moisture recovery.
Intelligent control and regulation sys-
tems assure that the optimum climate
is achieved right where it is needed. No
room is unnecessarily heated or cooled.
This reduces long-term costs.

1. You get what you pay for
When deciding between conventional
air-handling-systems and ones that are
“Life-Cycle-Cost”-optimized, taking
the short view by considering only the
initial investment costs usually turns
out to be a grave error. The user must
accept and allocate funds for very high
operating costs in the coming years.
But when you consider the fact that in-
vestment costs only occur once, and
on average, amount to only 10 % of the
overall costs in the life cycle, then it is
clear that decisions must favour air-
handling-systems that are optimized in
terms of “Life-Cycle-Costs”. As a rule,
these systems are amortized within the
fi rst year by the drastic reduction in
ongoing operating costs.
2. The difference is crucial
Different sites place different demands
on ventilation and air-conditioning-
systems. The specifi c requirements and
operating times play a pivotal role in the
design concept and cost considerations.
A school places different demands on
the air-handling-system than a hospital.
Sample consideration of operating times:
hospital 24 h/day, 7 days/week
school 10 h/day, 5 days/week
(taking into account holidays)
3. Intelligent design for lower
operating costs
Innovative ventilation and air-condition-
ing-systems have signifi cantly reduced
cleaning, inspection, and maintenance
costs. Intelligent measurement and
regulating units reduce the operating
complexity further. This saves time and
money.
4. Energetically thought through –

The European guideline 2002/91/EG “Overall
Energy Effi ciency of Buildings” is implemented in
accordance with EnEV 2006 and DIN V 18599.
The essential requirement in Article one of
guideline 2002/91/EG is:
(...) The goal of this guideline is to support the
improvement of the overall energy effi ciency
of buildings in the European Union by taking
into account the respective outdoor climatic
and local conditions as well as the require-
ments of the interior climate. (...)
We want you to make the right choice

Step 1:
Calculating the energy needs with AL-KO
“Life-Cycle-Cost”-optimize (“Life-Cycle-
Cost”-optimize is part of this software)
is based on DIN V 18599, part 3, of the
implementation of the EU guidelines for
overall energy effi ciency of buildings.
(2002/91/EG). The main focus in calcu-
lating the energy quantities is the elec-
trical power con-sumption of the fan and
the effi ciency of the heat and humid
recovery.
AL-KO software for quick selection of air-handling-units and calculation of “Life-Cycle-Costs”
With regard to non-residential buildings, in ad-
dition to the evaluation of the building shell,
the guideline requires inclusion of the entire
engineering of the building. The focus here is
air-conditioning engineering, lighting, and hot
water production. In the air-conditioning fi eld,
the essential requirements are getting energy
certifi cates and establishing inspection mea-
sures. Optimizing the operating economy and
energy consumption of the ventilation and air-
conditioning-unit is only possible by classifying
new and existing units. This makes air-condi-
tioning-systems signifi cantly more economical
to operate.
LCC methodology
12
The power consumption of the fan
has a big influence on energy costs.
Although the fan constitutes at most
only 3 % of the initial investment cost,
all by itself, it can comprise up to 70 %
of the air-handling-system‘s annual
operating costs! “Life-Cycle-Costs”-
optimized AL-KO units feature a rapid
amortization with low additional
investment expenses.
Fan selection:
The right fan concept saves you several
times the initial investment cost by
reducing the energy costs over the life
cycle.

Excessive operating costs in air-hand-
ling-systems are chiefl y caused by in-
suffi cient device cross sections and
excessive fl ow speeds.
An increase in the unit cross section
results in a signifi cant reduction in fl ow
speeds and the accompanying energy
costs.
To reduce costs further, it is therefore
necessary to adapt the air-fl ow-volumes
to the actual needs. Selecting the opti-
mum unit cross section in terms of
operating economy and the optimum
operating mode enables a signifi cant
reduction in “Life-Cycle-Costs”.

SIMPLE SELECTION OF ENERGY EFFI-CIENT AIR-CONDITIONING-UNITS WITH CALCULATION OF “LIFE-CYCLE-COSTS”
m i t L i f e - C y c l e - C o s t s - B e r e c h n u n g
Energy effi cient air-handling-units: AL-KO software for LCC-calculation
The evaluation, design and tender of
ventilation and air-conditioning units
in accordance with “Life-Cycle-Costs”
is not only surety for lowest possible
energy consumption costs, but also
considers further consequential costs,
such as maintenance and repair.
The energy effi cient concept and design
of air-conditioning units is the basis
for the requirements of the sustainable
building industry. Buildings must be
more effi cient – this is not only associa-
ted with the decisions of global climate
protection objectives and reduction of
the CO2 emission, but especially also
with signifi cant increase in the supply
cost of primary energy and the depend-
ence on the delivery of large quantities
of energy.
However, the most important:
Energy effi ciency saves much money!
Often, the cost of investment for air-
conditioning units does not increase
signifi cantly, however, the energy effi -
ciency and the potential for cost saving
increases enormously. This factor incre-
ases the profi t of the operating compa-
nies (at constant best air quality in the
rooms of the building), because of sub-
stantially lower units operating costs
and contributes to the competitiveness
and location security.
Energy quantity calculation iaw DIN V 18599-3 and economic calculation iaw VDI 2067-1 for lower “Life-Cycle-Costs”
AL-KO engineers will fi nd the most
energy-effi cient air-handling-solution
for your application
Energy effi cient air-handling-engineering means: low “Life-Cycle-Costs” Low “Life-Cycle-Costs” for air-condi-
tioning units are the result of energy
effi cient air-conditioning and adjust-
ment of a few parameters with the future
building operator (investor, builder,
owner, contractor).
Especially the operating time and op-
erating conditions, as well as the data
of the site of the air-conditioning are
decisive for the desired reduction in
the life cycle costs of air-conditioning
units.
In order to conceive the optimal (cost
reduced), air-conditioning unit for the
respective application (respective
operator), the appraisal of energy
effi ciency classes is indeed expedient,
but not suffi cient.
Alone, the calculation and evaluation of
the “Life-Cycle-Costs” of air-conditio-
ning units lead to the correct inform-
ative result. The air-handling-concept
with the lowest life cycle costs is the
most economic.
“Life-Cycle-Costs” are the result of
investment mathematical calculations,
which are implemented in the VDI 2067.
Basis for this calculation are energy
quantity calculations, in accordance
with DIN V 18599.
With the new software for design of
air-conditioning units with “Life-Cycle-
Costs” calculation, AL-KO offers the
specialist designer a selection of pre-
confi gured unit versions from a list and
then to compare these, with regard to
their expected „Life-Cycle-Costs“.

ENERGY RECOVERY
AIR-HANDLING-UNITS
2
Heat recovery and energy recovery is nota philosophy but an economic necessity
Heat recovery in air-conditioning systems with
nor-mal utilisation is always an extremely rewarding
business for operators and users of air-conditioning
systems because primary energy is saved (costs for
energy continually increase).
Even the government has responded and estab-
lished useful basic conditions by ratifying energy
conservation regulations (EnEV 2009 ff.) that
prescribe compulsory consideration of heat
recovery in Germany.
3
This does not only involve heat recovery
itself, but also the recovery of cooling
energy as well as moisture recovery or
dehumidification. In this way, the right
energy recovery system can be chosen
for each climate zone on the planet.
Today, we no longer have to discuss the
pros and cons of heat recovery, we just
have to choose the most economic
energy recovery system for the respec-
tive project.

Run-around-coil-systems
The thermal energy which is transmitted
into the supply air does not need to be
generated but is collected by using ener-
gy recovery systems out of the exhaust
air. By using energy-recovery-systems
in air-handling-units the investment-
cost will increase just a little bit but the
usage of energy- recovery-systems will
decrease the energy-cost signifi cantly.
An economic calculation of “life-cycle-
costs” will point the advantages of
energy- recovery-systems very well.
Reasons for using an energy-
recovery-system:
I saving thermal energy (heating
energy)
I decreasing of annual heating power
demand
I Saving thermal energy (cooling energy).
This means a smaller design of heat
exchanger, tubes and pumps as well
as the entire cooling equipment (com-
pressors, cooling units and exhangers)
and therefore less investment-costs.
I decreasing of annual cooling power
demand
I decreasing of CO2 -emissions
High performance run-around-coil-
system
I out-door-air is separated
from exhaust-air
I high performance series connection
of heat exchanger
I every exchange performance within
the run-around-coil-system is possible
I effi ciency of energy recovery up to 90 %
Circulation composite system
I effi ciency up to 75 % with

System description
Operation of the AL-KO
run-around-coil-system
I Use of high performance heat exchan-
gers in a multiple countercurrent
circuit. This achieves high annual
utilisation ratios of 80 %.
I Each heat exchanger has only one
mode of air-flowing through (fresh or
extract air) so that germs and contami-
nation cannot be transferred.
I The system is used during the winter
period to pre-heat the fresh air and in
the summer to pre-cool the fresh air
through adiabatic cooling of the ex-
tract air.
I Because of humidification of the ex-
tract air during summer period the air
is cooled and the cooling transferred
to the supply air. Humidity cannot be
transferred between the air-flows be-
cause the exhaust air temperature is
raised in the exhaust air heat exchan-
ger, it leaves the building without
moisture.
I Depending on the type of humidifier
(evaporation humidifier, high pressure
nebuliser, air washer) the humidifica-
tion is able to use service water, demin-
eralized or adul terate water.
I The AL-KO outside air heater can be
divided in accordance with VDI 6022.
The defroster with wide fin spacing, in-
stalled before the filter, raises the out-
side air temperature sufficiently to
avoid frost formation on the filter
medium and thus ensures compliance
with the relative humidity required by
VDI 6022.
I For dehumidifying an additional heat
recovery system exchanger is installed
after the dehumidifying cooler.

Rotary heat exchangers
So-called rotary heat exchangers
(rotors) are another highly effi cient
alternative for heat recovery. The heat
is not generated but recovered from
exhaust air. The advantages of rotary
heat exchangers are obvious:
On the one hand, the space require-
ments in the air-conditioning unit are
relatively small. On the other hand,
not only heat energy but also the cold
(e.g. summer operation of the plant)
or the moisture (sorption rotors) in the
exhaust air can be recovered and fed to
the supply air. Conversely, dehumidifi -
cation can also be achieved with sorp-
tion rotors. Firstly, in contrast to other
systems for energy recovery, thermal
energy (heat, cold) can be recovered
throughout the year and it doesn‘t have
to be regenerated involving sometimes
extremely high costs. Secondly, even
without a humidifi cation unit, (in winter)
a certain amount of moisture from the
exhaust air can be partially fed to the
dry incoming air from outside (fresh
air).

Cross-fl ow heat exchangers
So-called cross-flow heat exchangers

are a commonly used alternative for
heat recovery. Cross-flow plate heat
exchangers are sometimes relatively
cost-effective (depending on the size).
In contrast to circulation composite
systems or rotary heat exchangers, no
rotating parts and motors or pumps are
necessary. The return heat figures with
this system are lower, although they can
still reach up to 80 %. In these cases, the
investment costs are somewhat similar
to those for a rotary heat exchanger.
Another advantage of the cross-flow heat
exchanger is the prevention of contami-
nation of the supply air that can occur
due to any odours or emissions in the
exhaust air; this is achieved by the 100%
separation of supply air and exhaust air.

More heat recovery means less heating costsand a lot of savings
The more effi cient the heat recovery,
the less energy is used for heating or
cooling. In many cases, the operation
of a re-heater (e.g. electric heat exchan-
ger) is only needed on a few cold days
in the year. With high effi ciency levels
(return heat fi gure), often more than
90 % of the required heat energy can
often be covered.

The observation period is always 15 years.
Costs for maintenance and repairs are not
included. This life cycle cost comparison
clearly shows the relatively small differences
in the additional investment costs and also the
very large differences in the total costs
(investment and energy costs in 15 years).
The investment costs are already included in
the total costs (sum of costs LCC).
An energy assessment and comparison
is initially made when comparing energy
recovery systems with each other. These
energy values expressed in money and
costs appear very impressive and
striking. This economic assessment
involves the so-called „life cycle costs
analysis“ and provides reliable values to
decide on one energy recovery system
or another. This calculation of profitabili-
ty according to VDI 2067-1 (based on
the calculation for the amount of energy
according to DIN 18599-3) also consi-
ders specific basic conditions such as
the utilisation times of the system or
special energy buy-off prices.
To illustrate this, the calculation of
profitability was conducted for a central
ventilation and air conditioning system
with an air feed volume of 31,000 m³/h
with the following system comparisons

Heating for room heights up to 7 m Heating for room heights up to 5.7 m
Regarding the area of application and
buildings in which air heating and
cooling units are preferably employed,
a very important point is clear:
Many buildings are accessible to the
public. Often it is hardware stores,
supermarkets, exhibition halls, show-
rooms, shopping centres and all types
of commercial premises, which – for
the customers of our customers – are
conspicuously equipped with air heating
and cooling units.
The “DESIGN” distinguishes itself by its
appealing optics, the lower noise level
and special fi re protection class “V-0” of
the plastic cover.
The AL-KO air heater “DESIGN” distin-
guishes itself through a low noise level
combined with fi re protection assurance
and energy effi ciency. By virtue of the
elegant external of the “DESIGN”, the
professional planner must no longer
“hide” the air-conditioning units from
the architects, builders, but above all,
from the customers of our customers.

Aesthetics and comfort
For rooms with a high comfort require-

cold-water air cooling unit “DESIGN”.
Used in buildings with much public
access. The air cooling unit can heat as
well as cool according to each season‘s
requirement. Thus, it is possible to
implement air-conditioning in such
buildings such as hardware stores,
supermarkets, exhibition halls, show-
rooms, shopping centres etc. at low cost.

extend an already installed DESIGN
heat- ing unit for the cooling function.
The appropriate system components
must be retrofi tted on-site. Extensive
new piping is dispensed with, because
the existing heating circuit (provided
that it is only designed for “DESIGN”
units) can be used.

AL-KO “ENERGIE”
12
Air recirculation unit for energy-saving heat recovery
The AL-KO air heater “ENERGIE” is
designed for application in storerooms,
production facilities and assembly
shops. In the recirculation air mode,
the AL-KO “ENERGIE” pulls in in the
hot air accumulated on the hall ceiling,
caused by the thermal uplift and returns
this purposefully to the centre of the
room. Thus, the AL-KO “ENERGIE” is
a perfect supplement to the AL-KO air
heaters, to return already heated am-
bient air to the centre of the room and
must not be continually reheated. The
AL-KO “ENERGIE” also recommends
itself to supplement static heating
systems.
Accumulated waste heat recovery
From a physical point of view, warm air
in rooms rises. The resulting tempera-
ture lamination is approx. 1 K per metre
height of the hall. This behaviour vehe-
mently counteracts the objective, simply
to provide the lounge area with heat.
Operation of AL-KO “ENERGIE”
The ceiling fan ENERGIE pulls in the
hot air accumulated below the hall
ceiling and conveys this back into the
lounge area. Simultaneously, the air
fl ow directed downwards counteracts
the emerging warm air. The “ENERGIE”
is controlled by a separate control
cabinet with selectable switch-on
temperature.
Application areas
AL-KO ceiling fans “ENERGIE” can be
expediently used in all high halls in which
heat accumulates in the ceiling area. Be-
cause the units operate independent of
the system, a check should be carried out
after retrofi tting existing installations.
