Separated Combustion Propeller Fan
Unit Heaters
Separated Combustion Centrifugal Fan
Unit Heaters
The Trane separated combustion units
are designed for space heating in mildly
hostile environments. These units can be
installed where dusty, dirty, or mildly
corrosive conditions exist or where high
humidity or slightly negative pressure
prevail.
Typical applications are industrial work
areas with wood or textile dust, non-
explosive contaminated environments,
non-chlorine process areas, automotive
and truck garages and greenhouses.
Centrifugal Fan Unit Heaters
Centrifugal fan unit heaters are ideal for
commercial and industrial applications
where a low noise level is desired. Trane
centrifugal fan unit heaters which
operate at .2-inches W.C. are extremely
quiet.
Centrifugal fan gas-fired unit heaters
should be selected for applications
where ductwork or discharge nozzles are
to be used.
Propeller Fan Unit Heaters
The Trane gas-fired unit heater is a
complete heat generating and
distributing plant, equipped with
automatic safety controls, all packaged in
a modern, streamlined, space saving,
attractive casing for mounting near the
ceiling. Propeller units are basically zero
static pressure appliances. At no time
should ductwork be used with propeller
units.
The designs are certified by AGA and
CGA as conforming with standards for
safe and efficient performance.
These units achieve higher seasonal
efficiencies by using outside air for
combustion, overcomes slight negative
pressures near exhaust fans or paint
booths and isolates burner from dust,
humidity and chemicals. The combustion
process is separate from the
environment where the unit is installed.
A power venting system draws a
controlled quantity of combustion air
from outside the building. The same
system exhausts flue products to the
outside. The burners, pilot and flue
system are enclosed within the unit, thus
the whole combustion process is literally
unaffected by the atmosphere where the
heater is located.
