TriPac can eliminate unnecessary idling
Oct 1, 2005 12:00 PM
Thermo King has launched the TriPac auxiliary heating/cooling temperature management system, also called an auxiliary power unit or APU. The TriPac eliminates unnecessary truck idling, keeps drivers comfortable, and saves money.
The TriPac system consists of a combination of components that provide an efficient method for providing sleeper cab heating and air-conditioning, truck battery charging, accessory power, and truck engine block heating. A Thermo King two-cylinder diesel engine powers an air-conditioning compressor and a 12-volt alternator, both of which are the belt driven “automotive” style. These components power the air-conditioning system, keep the truck batteries charged and provide tractor engine heat. The truck engine block is heated by incorporating the engine coolant systems between TriPac and the truck engine. This approach is effective because the engines warm each other while running, to ensure easy starting in all climates. The system even incorporates engine coolant temperature sensing via an Arctic option.
Cab heating is provided via a fuel-fired heater that is efficient and compact. Accessory power is delivered to the cab by providing 12-volt DC. If 120 VAC is required, an optional 12-VDC to 120-VAC inverter can be provided. These components are all incorporated via a programmable microprocessor. The TriPac control panel is backlit and mounts in the sleeper compartment.
