APUs

Carrier Alternative Power Units (APUs) provide an energy-efficient solution to idling truck engines. These units provide AC current

Auxiliary power. An active alternative to engine idling.

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 Carrier auxiliary power unit (APU), you can turn off your engine, be comfortable, and turn down your operating costs. Externally mounted on the side rails, Carrier's APU is protected by a 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.
