TECHNICAL DATAUDSA

Within the V3 range there are two distincttypes of heaters;UDSA - models fitted with an axial fan.With a choice of 24 different units and arange of heat output ratings from 8 to 100kW, these models are available with bothhorizontal and vertical down flow air discharge.UDSBD - models fitted with centrifugal blower in horizontal or vertical orientation. Sixteensizes of heaters with heat outputs rangingfrom 15 to 64 kW.Both UDSA and UDSBD heaters are easy toinstall and they are suitable for a wide rangeof commercial and industrial applications suchas retail premises, sports and leisure halls andwarehouses to mention but a few.

Reznor V3 unit heaters are one of the mosttechnically advanced products available on themarket today. Incorporating a radical new heatexchanger and burner. V3 is compact, light-weight and delivers the highest possible

standards of energy efficiency andperformance.

The titanium stabilised aluminised steel heat

exchanger is particularly strong and durable

providing additional temperature resistance.

Its weld free construction ensures long life.

Patented self-aligning burner with

single orifice eliminates possible

flame impingement and premature

heat exchanger failure.

Up to 25% lighter than similar models and

easy to install.

Balanced flue wall terminal provides both flue

outlet and combustion air inlet, thereby reducing

installation time.

All connections (gas and electricity) are

accessible at one side of the heater.

Energy saving

Application versatilityBoth horizontal and vertical downflow units are

available.

Fourteen different heat outputs from 8 to 100 kW.

The smallest unit is only 310mm high - making

it ideal for mounting in confined spaces.

Units may be suspended or base mounted on a

suitable support (fixed or pivoting).

4-way heat exchanger achieves over 92% ther-

mal efficiency.

Reduced NOx emissions contribute to protect the

environment.

An improved airflow and a new louvre design

give longer air throws and significantly

reduce stratification within the

building. Consequently,

the units are particularly

suitable for well insulated

buildings. If necessary, de-

stratification fans can be installed.

The aerodynamic heat exchanger profile enables

the UDSA model to increase the airflow up to

40% with a 30% reduction of electrical

consumption.

Easy installation and maintenance

Extended operational life

Maintenance is very simple thanks to the useof a single gas injector

for all models.

CENTRIFUGAL MODELUDSBD

UDSBD

These indirect gas-fired unit heaters have

separated combustion and an atmospheric

burner. The units are equipped with a direct

drive centrifugal blower and they can operate

effectively at a resistance output of up to 150

Pa. Furthermore, there is a choice of three

types of air distribution: plenum type, standard

outlet grill (fitted with vertical louvres) and

downturn nozzles. The unit

Designed for recirculation and air distributionthrough ductwork UDSBD units are ideal for

open doorway heating (to prevent heat esca-

ping) or for providing temperature controlled

space heating.

is also available in

vertical downflow orientation in sizes 015, 025,

035, 043, 050, 055 and 064.
