Diamond Power Systems offers a diesel-powered APU that’s been approved by CARB (California Air Resources Board) and so doesn’t require a diesel particulate filter for operation in California and western States.

It runs sleeper air conditioning and heating systems as well as cabin household accessories. It also recharges the truck’s batteries, warms the engine, and monitors the batteries’ charge. Itís a fully contained unit in a shock-resistant, weatherproof compartment that mounts directly to the frame rail. The driver’s control panel gives the driver easy access to control all features including start/stop and HVAC systems from inside the cab or sleeper.

The APU measures 26L x 21D x 29H in. and is powered by a 14-hp, two-cylinder, water-cooled diesel engine.
