Features and Benefits
Separated Combustion Propeller Fan Unit Heaters
The Trane separated combustion propeller type unit heater keeps energy costs down by offering
80 percent thermal efficiencies. With model inputs available from 100 through 400 MBH, they
are designed to be installed in mildly hostile environments where dusty, dirty and mildly
corrosives exist or high humidity or slightly negative pressures prevail.
The Trane propeller unit separates the combustion process 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 gas products to the outside. The burners, pilot and
flue system are enclosed within the unit. The entire combustion process is literally unaffected
by the atmosphere in the space where the unit is located.
Combustion and exhaust air may be piped horizontally through a side wall, or vertically through
the roof via our standard two-pipe venting arrangement or optional concentric vent kit which
utilizes one 8-inch side wall or rooftop penetration for both the combustion and exhaust air. Both
venting systems are C.S.A. International certified.
Separated Combustion Centrifugal Fan Unit Heaters
The Trane separated combustion centrifugal type unit heater keeps energy costs down by
offering 80 percent thermal efficiencies. With model inputs available from 100 through 400 MBh,
they are designed to be installed in mildly hostile environments where dusty, dirty and mildly
corrosives exist or high humidity or slightly negative pressures prevail. This unit operates at a
static pressure up to 0.2” water column, and is available with a louvered (standard) or flanged
outlet (optional) when discharge duct work is desired.

Separated Combustion Duct Furnace
The Trane separated combustion duct furnace is designed for installation in dusty, dirty or mildly
corrosive environments or where high humidity or slightly negative pressures exist. Ideal
applications include HVAC equipment rooms, manufacturing facilities, automotive garages and
greenhouses.
