Who is RHOSSRhoss is a company of Irsap group specialised in the design and production of air conditioning
and air handling products and systems. For more than 40 years, Rhoss has been a guarantee for
innovation, quality and top level service. This is what makes us an ideal partner for HVAC system
specialists.
RHOSS's growth and development is an evolution that combines investments and projects
in order to make the company a point of reference also in international markets. Our re-
newal has followed market developments and customer needs, in particular off ering high-
ly effi cient products and systems that are in line with the requirements of the most modern
Green Buildings.
TECHNOLOGICAL INNOVATION FROM THE PRODUCT TO THE SYSTEM
Y-M.I.C.H. has been created, inverter technology used for chillers and heat pumps.
A MODULAR range of air han-dling units with regulation with high service levels.
Two other innovations in-clude Dry-Pool, the fi rst dehumidifi er for pools in R410A, with heat recovery and Yardy HP, a high perform-ance ducted fan coil unit.
Development of innovative so-lutions to maximise comfort and energy saving performance.
We have a permanent research contract with Universities to support innovation.
“Low consumption" technol-ogy for managing R410A chillers and heat pumps, to reduce seasonal energy con-sumption.
From machine certifi cation to system certifi cation in refer-ence to the main air quality and environmental comfort measurement standards.
Heating, cooling and hot water production solutions based on high performance, NF certifi ed heat pumps.
IR TECH, a radiant air conditioning division of Rhoss, off ers an advanced integrated system that maxim-ises comfort, reducing the system's energy require-ments.The innovative system was developed in Rhoss's new R&D Lab, which is able to simulate a building-unit system.
Conscious design for a conscious choice
RHOSS bases its design philosophy on one fundamental concept: testing the behaviour of its
produced machines in all the environmental conditions in which they can be used.
A responsible manufacturer must in fact provide designers with correct data regarding its prod-
ucts under all operating conditions, because each air conditioning unit must deliver a specific
energy performance that can vary based on geography, building features and use requirements.
With its testing rooms, Rhoss's R&D Lab provides its customers with a series of guarantees that
are necessary for a conscious design:
guarantee of performance under the design conditions, which are usually different than
Eurovent nominal conditions;
guarantee of efficiency at full load (EER, COP) or at partial loads (ESEER);
guarantee of continuous operation, especially under the most critical operating conditions:
simply think of severe climates where the ambient air can exceed 50 °C or go down below
–15 °C.
the possibility for the design or end customer to carry out customised tests
Therefore, Rhoss is able to offer products designed for large and small capacity systems, guaran-
teeing that all the components used are integrated together, with a perfect control logic.
This result can only be obtained in laboratories such as Rhoss's R&D Lab, that is, in a complex,
technically advanced structure that most other manufacturers today do not have.

EUROVENT CERTIFICATION FOR AIR HANDLING UNITS
Rhoss participates in the certification programme for air handling units with the ADV range that includes:• Certification of performance according to the EN 13053 Standard• Certification of the mechanical features according to EN1886• Energy classification of the machines
ECA CERTIFICATION FOR CHILLERS
The Rhoss chillers in the Y-Pack, Y-Power, Z-Power ranges and in the industrial range have also received ECA - Enhanced Capital Allowances - certification, which is a key programme from the English government that promotes criteria for energy savings and environmental wellness.ECA makes it possible for companies in the United Kingdom to benefit from tax incentives for investments in equipment, in the specific case of chiller assemblies, that satisfy certain energy efficiency values and are therefore able to contribute towards energy savings and a reduction in carbon emissions as set forth by the Kyoto protocol.
NF PAC CERTIFICATION FOR HEAT PUMPS
The Rhoss Mini-Y, Compact-Y and Compact HT heat pumps are NF PAC certified, which is a voluntary certification of quality that is issued by the French certification agency AFAQ-AFNOR. NF PAC applies to heat pumps with a heating capacity of up to 50 kW and certifies performance in terms of minimum COP, heating capacity and sound power level, in accord-ance with the requirements of the NF PAC Regulation. Before issuing the NF PAC certifica-tion, AFAQ-AFNOR carries out performance tests on the heat pumps representative of the certified ranges and performs company audits to evaluate manufacturer reliability.
Global services and solutions Rhoss Smile Service.
THE “VALUE” FOR HVAC SYSTEM USERSRhoss Smile Service aims to fi nd solutions to your problems, meeting all of your needs re-garding air conditioning, heating and air ventilation equipment installed all over the world. Rhoss Smile Service creates service programmes and instruments that makes it possible for us to always serve you better. Which are the most signifi cant added value aspects for a HVAC system user?
1. obtaining constant performance without problems or concerns2. optimising equipment operation3. minimising energy consumption4. keeping maintenance costs low5. eliminating operational losses6. limiting inactive times7. foreseeable cost management8. compliance with local governmental and environmental regulations
RHOSS SMILE SERVICE CONTRACTS - WARRANTY EXTENSIONExtended warranties are possible for all Rhoss units, which include labour and replacement parts for parts that are defective during the preselected extension period. Warranty cover-age requires the execution of all ordinary maintenance operations through the scheduled maintenance contacts (Basic, Program, Full Service and Global) in order to satisfy your needs, your company and your application. They are designed to off er operative effi cien-cy, extend the useful life of your system and help reduce operational costs. Selecting a Rhoss Smile Service contract is an antistress strategy.The advantages of purchasing a Rhoss Smile Service contract are unquestionable: in addi-tion to having greater response priority, maintenance and component coverage, customers who sign a contract have the advantage of effi cient planning and money savings. In fact, with a service contract administrative costs and internal and external labour costs are reduced substantially, and provide operational cost savings. The longer the contract, the more you save. Rhoss Smile Service contracts can be signed for a period of up to 10 years.
MACHINE FOR TEMPORARY USE - RENTINGThe right machine at the right moment and for the necessary amount of time: Rhoss Smile Service also means medium and long term renting of air conditioning and heat-ing equipment. Rhoss Smile Service off ers a wide range of versatile machines that can satisfy all cooling needs with an “all inclusive” formula. The supply foresees a turn-key rental, quick and timely coverage of any risk connected to maintenance and operating costs. The fi xed rates represent certain costs that simplify accounting and a company's fi nancial forecasts with rental fees being considered “operational costs” and therefore fully deduct-ible. Customers can add to or replace their equipment at any moment with a fee adjust-ment.The main fi eld of use are ice rinks (specifi c machines for working at low temperatures) and machines for the wine sector.
EXTRAORDINARY MAINTENANCE - UNIT RE-ASSEMBLYIncreasingly often, architectural barriers and structural constraints make it impossible to re-place units in areas that are diffi cult to reach due to weights and dimensions that do not conform with the available spaces. Rhoss Smile Service has a team of specialised techni-cians who are able to perform on site disassembly and reassembly operations for the machine to be positioned. If units not covered by Rhoss Smile Service contracts and no longer in the warranty period have defective vital machine components, the Rhoss Smile Service team is able to accept any request for service and will quickly organise: a techni-cal inspection, preparation of a repair estimate, repair service following approval of the estimate, 12 months warranty on the work that was performed and reactivation of the global warranty for an additional 6 months starting from the date the work was completed.

MODULAR is the new range of air handling units that is the result of RHOSS's experience in designing, planning and implementing products for the comfort segment.
• These units were designed to meet the specifi c needs of reliability, high performance, energy effi ciency and respect for the environment that are required today for public and private buildings such as hotels, large warehouses, stores, offi ces, business centres, restaurants, libraries and schools.
• MODULAR was designed to ensure a compact size and thereby meet the requirements of minimum dimensions and minimum service spaces typical of today's installations.
• In all of its confi gurations, with MODULAR you can select the regulation option that completes the machine supply with a microprocessor, user terminal, electric power panel as well as the auxiliary control components normally used for air handling such as sensors, dampers, actuators, motorised valves and other signalling devices.
• All of the elements are mounted and wired in the machine, simplifying the on site work, guaranteed by an inspection performed at the end of the line at RHOSS's factory.
• Each component was selected following a design coherency in order to maximise effi ciency and energy savings. From this point of view, it is now possible to select fans with an electronic changeover motor, which are available with the plug fan option for models up to and including 070.
• This new type of fan, in comparison to traditional systems, guarantees that less energy is absorbed by the ventilating section, making it possible to control and modify the rotation speed directly from the user terminal.
• MODULAR is based on a standardisation philosophy that focuses on supplying a product with advanced technology in a short period of time.
• Thanks also to the dedicated selection software and the navigation system that is based on the TYPE-FUNCTION concept, the MODULAR unit range is characterised by its extreme simplicity that makes it easier to consult and select from among the wide range of predefi ned confi gurations.
• RHOSS has directed its technical choices towards solutions that can guarantee fi rst-rate structural features: particular attention has been placed on resistance to positive and negative pressure in the various sections, leakage reduction, gaskets, insulation as well as reduction in thermal transfer.
• RHOSS has designed an exclusive structure that uses sandwich type self-supporting panels that are 50 mm thick and thermo-acoustically insulated with injected polyurethane or mineral wool.
• The MODULAR air handling unit casing was tested at the RHOSS laboratory - R&D Lab according to the criteria set forth by the UNI EN 1886 standard, reaching the performance classes specifi ed in the following tables (*).
• Compact
• Built-in regulation
• EC fans (models 015-070)
• Optimal service levels
• High standards according to EN1886

• The range includes 10 models that cover an air fl ow rate range between 1.500 and 17.000 m³/h with a frontal coil crossing speed of 2,5 m/s.
• Within the fl ow rate range covered by each model, the colours help with the selection of the size based on the desired handling performance:
- maximum coil crossing speed of 3,0 m/s for units with a cold coil and/or humidifi er;
- maximum coil crossing speed of 3,5 m/s for units with heating only.

DAMPER ACTUATORSAlready assembled and wired, these are the components that actuate the air passage dampers. Based on the machine confi guration, they can have an on-off or modulating control, with or without a spring return.
FILTER DIFFERENTIAL PRESSURE SWITCH This provides an alarm signal for a dirty fi lter that reaches the set pressure value limit. Assembled inside the unit in correspondence of the fi ltering section.
WATER COILS They feature the entire hydraulic assembly, including a three-way stopper housing valve, modulating servo control and balancing valves on the by-pass.
ANTIFREEZE THERMOSTATAssembled behind the hot coil, it protects the heat exchangers from the risk of freezing if temperatures go down below a preset threshold value, causing the fan to stop, the external air damper to close and the hot coil to be activated to restore normal operation.
TECHNICAL SPACE (for external installation)Included at the side near the regulation components.Made with pre-painted galvanized steel.
FAN DIFFERENTIAL PRESSURE SWITCHThis provides an alarm signal if there is no air fl ow, caused by a ventilating section fault. Assembled inside the unit in correspondence of the ventilating section.

Comfort rangeMODULAR 015÷170Selection: TYPE and FUNCTION
The ease in selecting a MODULAR range unit is based on the concept of TYPE and FUNCTION.The TYPE of unit solution is a major plant engineering requirement and it is related to a predefi ned number of FUNCTIONS.
TYPE EEXTRACTOR
Simple autonomous extractor or an extractor combined with a handling unit that works with primary air or 100% external air.
TYPE R100% RECIRCULATION
For 100% recirculation systems that do not require a combined extraction system.
TYPE F100% EXTERNAL AIR
For primary air or 100% external air systems.Possible combination with Rhoss (TYPE E) extractors or extractors not supplied by Rhoss.
TYPE MMIXING BOX
This makes it possible to manage the mixture of external and recirculation air.
TYPE VVERTICAL RECIRCULATION/EXPULSION BOX
This permits the expulsion of the extracted air and the mixing of external air with recirculation air.
TYPE HHORIZONTAL RECIRCULATION/EXPULSION BOX
This permits the expulsion of the extracted air and the mixing of external air with recirculation air. The horizontal implementation is recommended in areas with reduced height.
TYPE XVERTICAL CROSSED FLOWHEAT RECOVERY
This is necessary in the case of not only a request for handling but also for an energy recovery system in order to reduce consumption for air conditioning. The vertical implementation is recommended in areas with reduced surface space.
TYPE WHORIZONTAL CROSSED-FLOW HEAT RECOVERY
This is necessary in the case of not only a request for handling but also for an energy recovery system in order to reduce consumption for air conditioning.

When the regulation and power components of an air handling unit are assembled at the worksite, the following usually occurs:• an increase in installation costs (due to
impeding the worksite itself, uncomfortable work conditions and variable atmospheric conditions).
• a decrease in machine reliability and effi ciency.
ADVR: the strength of a winning proposalThe CTA ADVR range eliminates all of these problems:• There are no problems related to accessibility for assembling the
components in the best position for unit operation.• Maximum simplifi cation of installation and reduction of time at
the worksite.• Rhoss is the only contact and is also responsible for the machine's
CE certifi cation.• Optimisation of all machine performance.• Clear and competitive economic off er.

Advance RangeCTA ADV 240÷22920Eurovent Certifi cation
• 5 energy classes to make the right choice
In 2010 Eurovent fi nally introduced an energy classifi cation criterion also for air handling units.The new energy classifi cation will help designers, installers and fi nal users to select the product most suitable for the application.
Parameters taken into consideration• Maximum air speed across the fi ltering section.• Heat recovery effi ciency.• Heat recovery pressure drops.• Absorbed power factor .
Defi nitions of three types of machines1. From A to E for units with 100% recirculation and external
air T >9°C.2. From A to E for units with external air T ≤ 9°C and with partial to
total external air Fresh air.3. From A to E for stand alone extractors.
Immediately identifi able energy effi ciencythe 5 energy classes from A (for the highest energy effi ciency) to E (for the lowest energy effi ciency) off er the best solution for the requested energy effi ciency level, making it a simple and immediate concept.
Globally recognisable Based on a globally recognised standard (EN 13053), Eurovent energy classifi cation for air handling units considers parameters such as air speed, electric power absorbed by the fan motor and the heat recovery effi ciency.
A clear vision requires precisionPrecision is an indispensable requirement for the energy certifi cation of air handling units. Eurovent certifi cation is currently the only European certifi cation program that is able to guarantee this precision through programmed tests and measurements of the certifi ed machines.

Considerations regarding Life Cycle Costs for air handling unitsConsiderations regarding LCC are a very powerful instrument for evaluating energy consumption and total operating costs for the air handling units.If used in combination with the energy classifi cation, the customer can be sure to obtain exactly what he expects.
We no longer compare apples and orangesEurovent certifi cation provides a detailed model in order to obtain a clear image of the costs involved with the air handling system and also ensures that the data declared by the manufacturers who participate in the certifi cation program are comparable, exact and accurate.
The calculation takes the following parameters into account:• Air fl ow rate;• Supply temperature in winter and summer;• Thermodynamic functions inside the CTA (heating, cooling,
humidifying, dehumidifying);• Installation location climatic data;• Heat recovery effi ciency;• Energy consumption of the fans;• Operative installation time;• Investment costs;• Energy costs;• Maintenance costs.
LCC analysis and energy classifi cation:an unbeatable combinationThe data from Eurovent certifi ed air handling units can be directly compared and off ers a neutral base for calculating the LCC: in combination with the Eurovent energy classifi cation, the designer, installer and fi nal user obtain clear and precise data that confi rms that they made the right choice.

1. Economic bonds
• The selection of an air handling unit must not only be done based on its initial price must also accounting for the costs related to its use. Rhoss helps you minimise these costs thanks to its wide heat recovery range.
• It is estimated that, considering an average life time of 20 years for a tertiary application (the percentages are more unbalanced for industrial plants) the total energy expense to run the air handling system is around 80%.
• If you require maximum effi ciency from your air handling unit during its entire life cycle, you will surely fi nd the system most suitable for you within our off er that integrates the following basic principle: limit energy expenses guaranteeing constant effi ciency and reliability over time.
The life cycle costs of an asset must be understood as the total costs of that asset, for its entire operating life from its purchase to its phasing out, including:
initial investment cost + maintenance cost + energy expenses + fi nal disposal expenses
There are two fundamental reasons for carrying out this type of analysis when selecting an air handling unit: • It provides a decision making tool to help in the most
eff ective selection from among diff erent alternatives;• It provides a benefi t from an environmental point of view
because it minimises a system's energy waste.

TWINNED COIL HEAT RECOVERYOperating principle• The heat recovery with twinned coils consists in hydraulically
connecting a fi nned coil (in a closed circuit) located on the supply fl ow and one on the exhaust fl ow.
• In this way I have in winter mode a pre-heating of the external air operation, bringing the air entering the hot coil to a higher enthalpic level and in summer mode a free pre-cooling of the external air summer operation, bringing the air entering the cooling coil to a lower enthalpic level. This makes it possible to select a smaller winter heating coil and a smaller summer cooling coil.
• Average effi ciency levels: 45-55%.
Main features• Easy to install. • The system can be installed even if the air inlet and outlet are
far from each other. • Low investment costs.• Low energy consumption (circulation pump).• Medium maintenance costs.• No danger of cross contamination of the air fl ows. Optimal
solution for applications in hospitals/operating rooms, clean rooms…
• Med/low air side pressure drops.
Available options• Exchange coil customisation depending on the required effi ciency
levels (effi ciency and/or pressure drops).• Material customisation depending on the applications: pre-
painted copper/aluminium coils; copper/copper coils; copper/tin-plated copper coils; stainless steel coils.
• In the ADVR range, the twinned heat recovery is provided complete with water circuit and automatic system regulation that always guarantees the maximum energy savings possible.
RUN AROUND THE COIL HEAT RECOVERYOperating principle• The run around the coil run around the coil heat recovery consists
in hydraulically connecting a fi nned coil (in a closed circuit) downstream of the summer cooling coil and another upstream of the coil itself. The two recovery coils are connected together by a water circuit with a pump and regulation valve. This is used to regulate the capacity of the coil downstream of the cold coil, in order to modulate the post-heating request. In this way, it is possible to select a smaller cooling coil size and select a smaller size or even eliminate the summer post-heating coil.
• Average effi ciency levels: 45-55%.
Main features• Easy to install. • Possibility to install the system also without an inlet fan.• Low investment costs.• Low energy consumption (circulation pump).• Medium maintenance costs.• No danger of cross contamination of the air fl ows. Optimal
solution for applications in hospitals/operating rooms, clean rooms…
• Low air side pressure drops.
Available options• Exchange coil customisation depending on the required effi ciency
levels (effi ciency and/or pressure drops).• Material customisation depending on the applications: pre-
painted copper/aluminium coils; copper/copper coils; copper/tin-plated copper coils; stainless steel coils.

CROSSED-FLOW STATIC HEAT RECOVERYOperating principle • The plate heat recovery are static and do not have moving parts.
This guarantees extremely high operating reliability and safety.• The two air fl ows, Fresh air and expulsion, are divided at the
recovery unit inlet into two passages contained between two plates that carry either hot air or cold air.
• These passages are sealed with solutions appropriate for each application, to prevent the possible contamination between the air fl ows. The heat exchange occurs through the plates that make up the passage walls.
• To increase effi ciency, Rhoss uses particular exchangers. The plate surfaces have particular patented "turbulence" design geometries that make it possible to reach effi ciency levels of up to 75%.
Basic features• Low installation and operating costs.• High guarantee of fl ow separation.• No moving parts. • Easy to adapt to any use.• Manufactures with materials suitable for the characteristics
of the diff erent applications. • Low air side pressure drops.• Med/high effi ciency.• Easy to clean and minimum maintenance required.• Eff ective noise muffl ing.• Good quality/price ratio also for small air fl ow rates.
Available options• Extra sealing. To guarantee a better seal between the two air fl ows,
supplementary sealing can be applied on the heat exchanger. This option is recommended in particular applications such as for hospitals, clean rooms, etc.
ROTARY HEAT RECOVERYOperating principle • The air to air rotary heat recoveries used by Rhoss consist
of a cylindrical rotor containing thousands of channels and characterised by a large surface area, are activated by an electric motor that is equipped with a speed regulator, if necessary.
• In rotary heat recovery, the heat exchange takes place due to the accumulation of heat in the rotor. In fact, while the cylinder turns slowly, the expulsion air crosses half of the casing and transfers heat to the rotor matrix, which accumulates it.
• The Fresh air, that crosses the other half, absorbs the accumulated heat. As rotation continues, the parts that absorb and transfer heat are constantly inverted.
• The rotor's rotation speed can be constant or variable through a speed regulator.
• The exchange surface, with is very wide in relation to the volume, permits very high effi ciencies in comparison to other types of heat recoveries, reaching effi ciency levels of up to 85%.
Basic features• The high effi ciency and the possibility to recover both latent
and sensible heat (hygroscopic wheel) makes it possible to signifi cantly reduce a system's installed power
• Possibility to transfer latent heat.• Possible reduction of humidifi cation devices. • Medium pressure drops.• Medium/high investment costs.• Medium/high maintenance costs.• High risk of cross contamination: no air fl ow separation. Not
recommended for hospitals or applications with a high risk of fl ow contamination.
Available options• Hygroscopic treatment. The standard aluminium matrix used for the rotor can be
chemically treated with a potassium carbonate alkaline solution in order to create an oxidated surface that makes the rotor hygroscopic. The oxidation makes the surface porous on a microscopic level, making the transfer of humidity possible between two air currents.
• High effi ciency hygroscopic treatment. The rotor can be provided in special hygroscopic aluminium that
guarantees high performance levels.• Speed regulator. The speed regulator allows the rotation speed control of the
heat recovery, and is installed in the inspection side of the heat recovery near the motor.

INDIRECT ADIABATIC HEAT RECOVERY Operating principle• To improve the performance in summer mode of the sensible heat
exchangers, the most effi cient solution is to combine them with an indirect adiabatic cooling system (RAI).
• Rhoss has developed an advanced heat recovery system that integrates indirect adiabatic cooling with static, high effi ciency heat recovery. This system makes it possible to signifi cantly cool the expulsed air due to one or more humidifi cation stages, obtaining an outlet air temperature that is lower than the ambient temperature without the use of a cold coil, continuing to recover heat also if the external air temperature is lower than the ambient air. This cooling method is extremely economical and sustainable and makes a substantial resizing of the chiller or even its elimination possible.
Operations during the summer and other hot months• During the hot season, the system automatically activates the
indirect adiabatic humidifi er, which cools the expulsed air before it enters the heat recovery unit. This maximises the temperature diff erence between the expulsed air and the outdoor air, maximising system effi ciency as a result. If required, the controller activates the cooling coil and the post heating coil if necessary to obtain the exact thermohygrometric conditions that were requested.
Operations during winter and other cold months• During winter, the system maintains all of its energy advantages
deriving from its freecooling operation and/or from its substantial heat recovery, guaranteeing maximum energy savings in any environmental condition.
• Based on an enthalpic comparison between outdoor and ambient air and based on the percentage of desired Fresh air, the management system decides on the most economical operation between total free-cooling, partial free-cooling and partial heat recovery or total heat recovery.
• When the machine starts up, the unit will operate in total recirculation conditions in order to achieve the temperature desired as quickly as possible.
Parameters that infl uence system use• The parameters that infl uence the process most are the ambient
temperature and relative humidity and the effi ciency of the heat recovery.
• Also the relative humidity of the outdoor air is important, because at lower humidity levels, the environment can be kept at relatively low humidity levels, improving system eff ectiveness.
• It is important that energy savings evaluations are done based on actual system operating values.
Main features• Compactness, also for large sized machines.• A unit that is self-adaptive to variable air fl ow rates.• Heat recovery system with effi ciency up to 75%.• Minimised air side pressure drops.• Extremely precise regulation components. • Integrated regulation software dedicated to energy
savings.• Plug&Play unit with regulation and integrated fi eld
elements
Available options• Self-cleaning function The advanced recovery system has a self-cleaning ozone
device in order to maintain system effi ciency and prevent the formation of mould, algae and bacteria.
NOTE: to maximise energy savings, RAI is always combined with the use of free-cooling.For more information regarding possible energy savings and the climates in which this system can be best used please contact our technical sales support at Rhoss Spa.

DIRECT ADIABATIC COOLING Operating principle• Direct adiabatic cooling (RAD) is based on a simple principle:
water in contact with air evaporates spontaneously, taking heat from the air; as a result, the air is cooled and humidifi ed at the same time.
• The power taken from the air is equal to the latent evaporation heat, which is assumed as being equal to 680 W/Kg/h of evaporated water.
• The effi ciency of this type of heat recovery is a direct function of the amount of water evaporated in the unit of time and of the evaporation speed (that is, air water exchange surface).
• Rhoss off ers various adiabatic humidifi cation solutions: with nozzles, evaporative coils (both with or without water recirculation) or with pressurised water sprays depending on the system's energy and water availability.
Parameters that infl uence system use• The outdoor air is cooled by means of water humidifi cation
until reaching a limit value related either to saturation or the obtainment of absolute humidity at the inlet point. Therefore it is the relative humidity of the outdoor air that determines system eff ectiveness: areas with lower humidity are more suited for adiabatic cooling
Main features• Simple installation and integration in the unit.• An inlet fan is not required.• The system can be installed even if the inlet and outlet are
far from each other. • Low or no investment costs (as it uses a humidifi er that is
already foreseen for winter operation).• Low energy consumption.• Medium to low maintenance costs.• This type of recovery increases air humidity, therefore it is
convenient when an adiabatic humidifi er is suitable for the environment.
Available options• Ozone hygenic system Treatment of the evaporator supply water with an ozone system
to prevent the formation of algae, mould, bacteria and viruses (also legionella).
NOTE: to maximise energy savings, RAD is always combined with the use of free-cooling.For more information regarding possible energy savings and the climates in which this system can be best used please contact our technical sales support at Rhoss Spa.

Variable conditions: the fl exibility of our proposal
• In hospital environments and in controlled contamination environments in general, the complexity of the system and the air handling units in particular can vary greatly depending on the type of area requiring air conditioning. The critical zones (such as operating rooms, mortuary rooms, rooms for immunodepressed individuals, analysis laboratories etc.), semi-critical zones (emergency room, hospital rooms, hallways etc.) or non critical zones (offi ces, waiting rooms, etc.) have very diff erent requirements for fi ltration, ventilation and for controlling the thermohygrometric parameters. Rhoss is able to supply the best solution for each of these requirements providing the designer and technical offi ces with all of its experience and professionalism.
• Continued technological evolution and the continuous updating of the reference standard framework require constant replacements to be made to HVAC systems in hospital systems. Our R&D group works constantly in order to off er products that comply with the current regulations and to provide the best technology in the industry.
• There is constant pressure to minimise investment and operating costs for systems while still maintaining or even improving levels of quality, comfort and service. Rhoss is able to off er products that provide great energy savings, making it possible for sanitary system operators to minimise the life cycle cost of the aeraulic systems.
Rhoss's off er for the hospital sector
The ADV health care series was designed according to the directives of the EN13053 standard. All of its components were selected and studied to minimise energy consumption (with particular focus on pressure drops) and maximise the system's overall energetic effi ciency. The following range features only provide an overview of the solutions off ered to the hospital sector and are not meant to represent a design guideline:
STRUCTURE• The machine is completely inspectable due to large access
doors. Each section subjected to frequent maintenance (humidifi er, fi lters, fans) can be supplied with illumination and a large dual pane inspection window, making visual inspections easy.
• The inner structure is completely free of corners or protuberances and only rounded profi les are used. This reduces air friction on the surfaces, the accumulation of dirt or washing liquids inside the unit.
• The material available for the panelling and the structural work guarantee the chemical resistance and bacteriological cleanliness levels required for contamination control.
• The stainless steel condensation collection pans are placed along the entire length of the machine in order to clean all components involved in the fl ow.
FANS AND HUMIDIFIERSThe fan sections can be supplied with diff erent confi gurations depending on specifi c requirements:• Classic belt and pulley fans equipped with an inspection device
and water drain in the envelope to permit its washing. Available in a version with a dual motor or dual complete fan section.

• Inverter activated "plug fan" fans for easy and complete cleaning of the sections.
Also available in a version with a dual reserve fan sized between 50 and 100% of the fl ow rate.
• Steam humidifi er with autonomous producer with immersed electrodes/electric/gas heaters.
• Distribution steam nozzles for hospital environments. • For some applications, high pressure adiabatic humidifi ers are
available that make it possible to precisely control ambient humidity without risks for the air salubrity.
• For all humidifi cation sections, the distances between the components are suitable calculated to guarantee proper steam absorption.
• The soundproofi ng sections are equipped with a special protection to prevent the particles from being released during machine operation and therefore pollute the air fl ow.
Innovation at the service of the health industry
Thanks to the synergy created between Rhoss's R&D group and its industrial partners and the possibility to test and validate the various technical solutions in our R&D Lab, we are able to off er a series of innovation solutions in terms of hygenic systems that aim towards reducing the airborne microbic load as much as possible.
• The use of UV germicide lamps: this provides a strong germicidal eff ect through the emission of ultraviolet rays that sterilise the air and the surfaces they reach. Rhoss is able to maximise the germicidal eff ect of the rays by using an extremely refl ective installation surface and by carefully studying the best position within the CTA.

HIGYENICAL AIR TREATMENT:patented system for ADV Rhoss AHUs sanitation
From the exclusive technical partnership among vergreen Tecno-plants and Rhoss has born Hygienical Air Treatment System (HAT). Thanks to H.A.T. Rhoss widens the traditional concept of air treatment , founded on the classical vision of control of air temperature and humidity parameters, introducing a third variable: the control and reduction of the microbiological risk of contamination.The use of this technology in AHUs, contributes actively to resolve an issue that generally aff ects the whole HVAC system.From this new concept of air treatment comes out the need of an integrated product able to combine the thermodynamic performance of the unit with the advanced indoor Air Quality control.In this optic borns the technical partnership that led to the development of Hygienical Air Treatment System among Rhoss and Evergreen Tecno-plants, an Italian company leader in the market of the ozone sanitation systems. This technology has been used for several years and with considerable success in the Agro-foodstuff process industry and in the swimming pools.
Ozone (allotropic state of oxygen) is an unstable gas composed of trivalent oxygen (O3) that does not leave any trace of chemical residue. Its elevated oxidizing power and its natural tendency to return to oxygen (O2) make it a product with high usage potential in many applications for air treatment as the microbiological contamination control and the deodorization.In nature it is the element with the strongest oxidation power, after fl uorine, with 2,07 V, and works oxidizing the cell’s membrane which is the main target of its antimicrobial action.
Some of the most important advantages achievable with the Hygienical Air Treatment system
• Elimination and/or inactivation of bacteria, moulds, viruses, spore from all the surfaces, even those diffi cult to reach with other cleaning systems (as fi lters, inner side of coils…)
• Possibility to implement the system in adiabatic humidifi ers both in the existing units and in new installations off ering an interesting cost-benefi t balance.
• Self sanitation of AHU.• Elimination of undesired odours from the environment.• Reduction of the environmental impact of industries (ISO 14000,
EMAS).• Higher effi ciency of heat exchange coils and of the unit on the
whole due to the absence of bacteria and moulds proliferation.• Optimization of the sanitation protocols and compliance with
Legislative Decree no. 81, 30/04/2008.

Application Sectors
• Public communities (Collages, schools, barracks)• Tertiary plants with high infl ux of people ( shopping centres,
cinemas, meeting rooms)• Hospitals, operating theatres, doctor’s offi ces, clinics, labs.• Swimming pools, public sport/fi tness centres, spas.• Pharmaceutical, agro-foodstuff s, chemical industry.• Wine industry.
Hygienical air treatment can be installed:• In ADVR plug and play units with factory fi tted electronic control• In ADV units where the control system is supplied by a third part company.All the HAT system components are installed inside a technical compartment in the AHU and completely integrated in the unit.
System Description
H.A.T is a patented at European level system integrated in our AHUs. It saturate the inside of the unit acting uniformly on all components (coils ,fi lters, fans, housing) being active also in the most narrow zones unreachable from other systems currently in use. The inactivation of bacteria, moulds, yeasts, parasites and viruses occurs also at low ozone concentrations and with short contact times through the complete control of the oxidizing power of ozone itself. The management is done completely automatically by the electronic control that via the O3 air sensor detection is able to modulate, manage and control the entire cycle.
Sanitation cycle
The sanitation cycle can be divided into three phases: Phase 1: ozone generation.Phase 2: control and maintenance of the Set Point Level.Phase 3: catalyst that ensures the complete conversion of ozone into oxygen.
It’s important to note that in the fi rst phase ozone is not generated through under pressure systems or gas cylinders that require storage and disposal, but, thanks to the technology we use, is generated on site using directly the oxygen available in ambient air in which the unit is located.

DRY-POOLSELECTION SOFTWARE
FROM THE SYSTEM…• Air conditioning for an indoor pool has very diff erent requirements in comparison to a typical system for residential or commercial users.
• In order to make the sizing of these systems easier, Rhoss has created a selection program that can be used to accurately calculate the rate of evaporation generated in these particular environments.
• All of the fundamental parameters necessary for determining the work load of the dehumidifi er are
entered in the calculation tool. These parameters include the temperature and relative humidity of the air in the room, pool surface area, water temperature and occupation rate.
• To make the selection more accurate, also other elements are considered such as the number of pools and their water volume, the cubage of the room, the number of spectators as well as the presence of special water games.
