The self-contained Powerhouse ™ DWS-APU circulates water or coolant with an electric water pump powered by an alternator that is driven by a small EPA-certified onboard diesel engine. An optional electric oil pump can be added to heat engine oil by circulating it through the block.
The modular frame and cage design of the DWS-APU protects components, and its compact size lets it fit in a variety of locations.
