Avant Garde ECO Fan ConvectorsECO 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

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.
