“An auxiliary power unit (APU) is a product that provides cooling, heating, and electrical power for hotel loads in the truck cab when the tractor main engine is off. It also maintains the tractor battery charge level and can be integrated into the tractor engine coolant system to improve starting capability in low ambient environments.”
