Carrier-Manufactured ComfortPro Diesel Auxiliary Power Units Now Available for Trucking Applications


The complete line of ComfortPro diesel-powered auxiliary power units (APUs), now manufactured by Carrier Transicold in Athens, Georgia, is available for trucking fleets and owner-operators looking to reduce fuel consumption while complying with anti-idling regulations. Carrier Transicold is a part of UTC Climate, Controls & Security, a unit of United Technologies Corp.

The Carrier Transicold dealer network has sold and serviced ComfortPro APUs since 2006, but earlier this year Carrier Transicold acquired select IMPCO road transport product lines, including the ComfortPro product line and manufacturing rights, from Westport Fuel Systems, Inc. An advanced assembly line for APUs was subsequently added at its flagship refrigeration manufacturing facility in Athens.

The latest ComfortPro models were showcased at the North American Commercial Vehicle Show in Atlanta this week.

“ComfortPro diesel APUs are the trucking industry’s all-around performance leaders,” said David Brondum, director, product management and sustainability, North America Truck, Trailer, Rail, Carrier Transicold. “No other APU offers the full combination of air conditioning, heating, cab power, engine warming, truck battery monitoring and charging, along with optional shore power connectivity found in ComfortPro diesel units.”

Fully featured ComfortPro diesel APUs provide 12,000 BTUs of cooling and up to 10,000 BTUs of heating for year-round driver comfort. Additionally, the 6 kW generator provides ample power for hotel loads, while also helping to maintain truck battery charge and automatically keeping the truck engine warm in cold weather.

To maintain climate control and cab power, ComfortPro APUs consume a small fraction of the fuel used when a truck engine idles, thus reducing overall emissions for compliance with state and local anti-idling laws.

Two fully featured diesel-powered ComfortPro units are offered – integrated and stand-alone. A third, power-only model provides electricity for household accessories for applications where no cab climate control is needed. With the integrated model, tractor engine warming is provided via APU coolant exchange. The stand-alone model provides the same capabilities as the integrated APU but the tractor and APU coolant systems are independent, with the ComfortPro APU’s generator powering the tractor’s block heater to warm the engine.

When plugged in to a 110/120-volt source, the ComfortPro APU’s shore power option enables functionality without running the APU’s diesel engine. The optional ClearSky diesel particulate filter can further reduce emissions as required in California for ComfortPro APUs used with Class 8 tractors with 2007 or newer engines.
