Avant Garde ECOECO models are for use in conjunction with low return

temperature systems (i.e. condensing boilers).

The Avant Garde Series AM and BM fan convectors is the

next generation heat emitter. Careful and ingenious design

allows condensing boiler plants to operate at maximum

efficiency at all times and with the minimum capital

investment.

Traditional low-pressure hot water (LPHW) heating systems

operate at 82oC flow and 71oC return during peak loads

on both compensated (radiators etc) and constant (fan

convector etc) temperature systems.

The Dunham-Bush Avant Garde unit is designed to operate

at 55oC flow and 35oC return during peak loads, whilst

maintaining the same duty, options and features as Dunham-

Bush’s extensive range of Series AM and Series BM fan

convector heaters.

• Boiler return temperature is always below 55oC, ensuring

the boiler is in condensing mode at all times

• Increased differential water temperature across the coil,

reduces pumping energy by up to 87%

• Decreased flow and return temperatures reduce standing

losses from pipework

• Low water content and thermal mass of the unit minimises

the response time, avoiding a protracted warm up period

and overshoot

• Integral 4-port valve prevents wasteful natural convection

during mild conditions

(2-port valve option available on request)

• Option of EC motors is available reducing electrical

power consumption by up to 80% compared to a standard

AC motor

Series SV Smart-Vector The Smart-Vector has been developed to provide an effective

solution for installation in classrooms, particularly when

Building Bulletin 101 is a requirement. Smart-Vector can

also be used in offices and other spaces where the highest

standards of air quality are essential for the well-being and

productivity of the occupants.

The Smart-Vector range comprises five models in nominal

heat outputs from 1.4 to 13.6kW and four casing sizes

ranging from 689mm to 1495mm wide.

Nominal outputs are based on LTHW 80/70°C flow and

return temperatures and an 18°C ‘air on’ temperature using

a WA2 coil. Alternative operating conditions and coils are

available.

Each unit incorporates an infinitely variable fan speed motor,

a modulating mixing damper, and a 2-port or 3-port control

valve, all controlled by 0-10V dc control signals. In addition,

each unit has a frost protection override thermostat as

standard.

The basic control option comprises a wall-mounted

controller, which measures temperature and CO2

concentrations and controls the mixing damper and control

valve actuators accordingly. It also controls the fan speed,

whether in manual or automatic modes. The controller also

has an RS485 communication port to allow interface or

communication with the BACnet BMS system where required,

thus allowing time scheduling, set point changes, integration

with other H&V plant and interrogation.

Other BMS protocols and controllers are available upon

request and these may include Modbus, fitting ‘free issue’

controllers, leaving air sensors, fan failure monitoring, and

‘spring return’ actuators

Sentry and Sentinel door curtains provide the perfect

solution to maintaining comfort conditions in commercial

and retail premises where the entrance doors are

permanently open to encourage higher footfall. Providing a

virtual barrier separating indoor and outdoor environments,

they will reduce heat losses while conditioning incoming air

efficiently.

SentrySentry door curtains can be utilised as either a door

curtain, which elevates the space/room temperature slightly

creating a barrier to help prevent the ingress of cold air

into the building or they can also be used as a door heater,

elevating the air temperature across the doorway.

Sentry door curtains are available in a range of models

suitable for horizontal or vertical mounting. Each model is

available with left or right coil connections and top or back

pipe entry into the casing.

There are four models, CH (cased horizontal), CV (cased

vertical), BH (basic horizontal) and BV (basic vertical) in 3

overall lengths, 1000, 1500 and 2000mm and 3 nominal

outputs 5, 10 and 15kW.

All Sentry door curtains comprise forward curve centrifugal

Finvector Finvector perimeter heating is tailor made to meet the

heating requirements of modern buildings, particularly those

with significantly exposed exterior walls and large glazed

areas.

Modular in design to ensure ease of installation, Finvector

will reduce heat losses while providing flexible comfort

heating.

Finvector has been applied successfully to heat many

types of buildings, such as office blocks, schools, colleges,

universities, libraries and hospitals.

It is particularly suitable for installation beneath large glass

areas featured in many modern buildings, since it offsets

down draughts and ensures comfortable conditions.

Finvector is also ideally suited for heating large spaces,

subsequently to be divided into smaller units. The design

and construction of the casing is such that the modular

features of the building can be matched, permitting

partitioning to be re-sited at will, without the necessity

to make major alterations to the heating equipment.

Alternatively where the application is non-modular, the

design permits flexibility, and adjustment to the overall

length of casing run is possible, due to the overlap of the

front plate on the make-up plates, end cap and corner

pieces.

The overlap and front plates in relief feature can be used to

emphasise the modular building construction when the tailor

made Finvector equipment is selected to follow the column

and window mullion positions.
