The ComfortPro Electric Auxiliary Power Unit (APU) from Carrier Transicold provides quiet, emissions-free truck cab cooling while delivering a long run-time. This APU is powered by four Group 31 AGM batteries charged by the truck’s alternator. The APU provides 7,500 BTU/hour of air conditioning for up to 11 hours. With a simple design and only a few moving parts, there is no engine-related maintenance such as oil, fuel, or air filter changes, according to the company. This unit is easy to install and can help reduce truck engine idling, helping drivers comply with local and regional anti-idling regulations while saving fuel and reducing engine wear.
