Reznor V3 unit heaters are one of the most
technically advanced products available on the
market today. Incorporating a radical new heat
exchanger and burner. V3 is compact, lightweight and delivers the highest possible
standards of energy efficiency and
performance.
Within the V3 range there are two distinct
types of heaters;
UDSA - models fitted with an axial fan.
With a choice of 24 different units and a
range of heat output ratings from 8 to 100
kW, these models are available with both
horizontal and vertical down flow air discharge.
UDSBD - models fitted with centrifugal blower
in horizontal or vertical orientation. Sixteen
sizes of heaters with heat outputs ranging
from 15 to 64 kW.
Both UDSA and UDSBD heaters are easy to
install and they are suitable for a wide range
of commercial and industrial applications such
as retail premises, sports and leisure halls and
warehouses to mention but a few.

UDSA
VERTICAL MODEL
To ensure that heat losses through the roof are
kept to a minimum and to avoid the occurrence
of stratification, it is possible to suspend the
UDSA unit in a vertical orientation. This way of
suspension allows the unit to dually operate as
a heater and as destratification unit.
The option ‘vertical orientation’ (option number
205.8) can only be applied on the UDSA
models 015, 025, 035, 043, 050, 055, 064,
073, 085 & 100.
All vertical UDSA models are fitted with a 4way outlet grill (no louvres) and can be
functioning as a destratification unit by placing
a destratification thermostat (option 904) on the
unit. The unit now helps ventilating and
recirculating the warm air towards the floor,
resulting in energy savings and climate comfort.

CENTRIFUGAL MODEL
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 is also available in
vertical downflow orientation in sizes 015, 025,
* outlet grill is optional
035, 043, 050, 055 and 064.
Designed for recirculation and air distribution
through ductwork UDSBD units are ideal for
open doorway heating (to prevent heat escaping) or for providing temperature controlled
space heating.

1) Gas appliance classifications for approved venting methods based on
CEN report - CR1749:2001.
2) Height from floor to bottom surface of the heater. These are RECOMMENDATIONS ONLY. Positioning of unit heaters for proper
performance is application dependent. Operation is affected by other
air moving equipment in the space, obstructions to the airflow,
draughts and/or close proximity doors or windows, etc. Care should
be taken to avoid mounting the heaters above these recommendations, unless downturn nozzle options are used, as significant
stratification may occur, resulting in poor floor coverage and higher
energy losses trough the roof structure.
3) Isothermal conditions , 20 °C ambient air temperature , discharge
louvres , zero deflection , v=0,5m/s.
4) dB(A) values at 5 meters from the unit with reference circumstances
A=160m² and Q=2.
5) dB(A) values at 5 meters from the unit in free field.
