 CABINET HEATERSThe Reznor free
standing range of cabinet warm air heaters combine
innovative design techniques and proven heat exchange
technology to produce units that are cost effective,
efficient and aesthetically pleasing.
Ten
model sizes cover heat outputs from 31kW to 289kW and are available as free
standing vertical units or, alternatively, as horizontal units.

 SPECIFICATION
HEAT EXCHANGER
The
combustion chamber is manufactured from high quality heat
resisting stainless steel and has a large surface area
and volume to avoid localised hot spots and to ensure
long life. A tubular cross flow heat exchanger provides
excellent fuel economy and the heat exchanger tubes are
expanded into the collection boxes thereby eliminating
the possibility of weld failure.
The complete assembly is mounted to allow for thermal
expansion to counteract the effect of thermal stress.
AIR HANDLING
Double inlet high efficiency centrifugal fans circulate air across all the
heated surfaces to give low surface temperatures and
maximise efficiency. Fans on models 29-1 to 88-1 are direct driven using
a single phase motor. All other models are driven by a heavy duty three
phase motor and v-belt system.
Air discharge is via nozzle outlets, or a four way louvred head.
Alternatively units may be installed with a fully ducted
distribution system.
CABINETS
The cabinets are constructed using a full pentapost frame and double
skinned panels with an inner galvanised steel skin. All panels are
easily removed for servicing.
Units are finished in a durable two tone powder paint. Four mounting
feet are incorporated into the cabinet to ease on site handling. After
location, these feet may be removed or left in position to raise the air
inlet away from the floor to minimise the ingress if dust
FUEL
Heaters
are available to operate on either natural gas (G20), Propane (G31), 28
or 35
sec oil. Gas fired units are fitted with a fully
automatic forced draught burner complete with full safety
controls and the heaters are tested and approved to the
relevant CE standards. Oil fired models are supplied
complete with a fully automatic forced draught pressure jet oil burner
complete with safety controls and matched to each heater for optimum
flame shape and efficiency.
CONTROLS
A combined
fan and limit thermostat is fitted on all heaters, which
delays fan start-up until the heat exchanger has reached
operating temperature and continues to run the fan after
the burner switches off until the remaining heat is
dissipated. In the event of overheating, the unit would automatically be
shut down by the limit thermostat.
On vertical models, time and temperature controls
comprising digital time switch, room thermostat and frost
thermostat, are pre-wired to the heater to simplify
installation. Horizontal models are supplied
with separate remote panel. Remote panels may also be supplied as
an optional alternative on vertical models.
