Auxiliary Power (APU3)

The Calatherm APU 3 is a diesel auxiliary power unit that provides dedicated vehicle air conditioning when the main engine is not in use, making it ideal for ICE vehicles that need an independent source of auxiliary cooling. Powered by a compact diesel engine driving a twin belt-drive scroll compressor and dual air handling units, it keeps operating conditions comfortable across a wide range of ambient temperatures. Built into a heavy-duty, low-maintenance modular chassis, the APU 3 is designed for continuous stationary operation in harsh conditions, while helping to cut fuel consumption, reduce engine wear and lower running costs.
