Auxiliary Power Unit (APU)

Idling a tractor engine for in-cab comfort or to ensure cold starts is very costly. It increases fuel cost, engine hours, engine maintenance and service cost. With the ComfortPro auxiliary power unit, you can turn off your engine, turn down your operating costs and still be comfortable. Externally mounted on the side rails, the ComfortPro APU is protected in its own weatherproof compartment and runs off the truck’s fuel supply. This innovative hybrid diesel-electric system saves fuel, runs quieter than the truck engine, reduces emissions and provides reliable all-night comfort for the driver.

The ComfortPro APU features the same award-winning all-electric DELTEK™ architecture featured in the Carrier Vector™ product family. The ComfortPro APU powers its proven generator with the same diesel engine featured in Carrier transport refrigeration systems. All other components are electrically operated and located away from the road to protect them from the harsh road environment, ensuring reliability.
