The ComfortPro Auxiliary Power Unit (APU), an anti-idling solution for the trucking industry from Carrier Transicold, has been improved with a 1,000-hour service interval, industry-standard R 134a refrigerant and a powerful 60-amp alternator. These are among new performance-boosting enhancements that also reduce lifecycle costs. The ComfortPro APU provides air conditioning, heating and household electrical current for a truck sleeper cab, battery charging and truck engine warming. This APU offers an all-electric architecture with the Deltek hybrid diesel-electric technology found in Carrier's Vector 1800MT trailer refrigeration units. A larger oil reservoir and new oil filter has doubled the oil-service interval. Moving to R-134a has also brought the ComfortPro's refrigerant in sync with automotive air conditioning systems, making service simpler for technicians due to standardized parts and procedures. The new alternator provides 50 percent more power than the original.
Other improvements include a new condenser with a proven fin-and-tube design, use of a thermostatic expansion valve rather than a capillary tube mechanism, and addition of a low-pressure sensor to protect the unit by shutting it down in the event of a refrigerant leak.
ComfortPro APUs reduce idling by up to 90 percent, saving thousands of dollars annually in fuel costs, the company says. They also reduce emissions, engine wear and associated maintenance, and help truckers comply with anti-idling regulations. The unit's energy source is a 4,000-watt generator driven by its diesel engine. For high reliability, its air conditioning system uses a sealed electric compressor located inside the cabin.
