Carrier’s ComfortPro electric auxiliary power unit is designed to provide quiet emissions-free cooling with a long run time facilitated by four Group 31 absorbent glass mat batteries that are charged by the truck’s alternator. The APU’s power management technology is engineered to maximize efficiency and provide 7,500 Btu of air conditioning for up to 11 hours. The unit locates the refrigerant compressor outside the truck cab, which contributes to quiet operation, and offers several options to expand capabilities for heating, power for hotel loads, shorepower connectivity and truck engine preheating. Also, with fewer parts, less service is needed, with no engine-related maintenance such as oil, fuel or air filter changes.
