Used trailer mounted engine driven Polartherm 400,000 BTU portable duct heater. Heater is fully self-contained and can provide up to 1900 CFM of hot air through 12" flexible air ducts that can be routed from the unit to the area to be heated. Unit was originally designed to be used at cold climate airports for heating the aircraft and aircraft personal during servicing and startup. This heater would be great for construction sites, remediation sites, drying flooded or damp areas or basements or even by an exterminator for killing bed bugs.  

The system uses a fuel oil burner to fire the furnace. The combustion blower/fuel oil burner and heater fan get their 120V power from the engine driven alternator. Engine is a 6 HP Yanmar diesel engine. There is a 52 gallon onboard fuel tank to power the diesel engine and furnace. Engine and other functions are controlled at the operators panel. Engine is started and allowed to warm up and the heat level is selected. Heater will provide hot air at the setpoint that is selected by kicking the furnace on and off to keep the temperature within the range. Unit can also be operated in vent only mode which operates just the blower without heating the air.

Unit is used and in very good condition.  We tested the operation and it worked well as can be seen in the video.  The unit has about 2100 hours of runtime.
