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.

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.
