If a class 8 truck is the heart of your business, we'd like to suggest an addition that could put years on its life and money in your pocket. Our truck auxiliary power system will be your best friend. It extends engine life, saves fuel, reduces air and noise pollution, provides back-up electrical power while main engine is operational, runs the heating and air conditioning systems, provides back-up air supply for primary and secondary air systems, supports air starter operation, provides for all your power needs including running lights and communications while main engine is off, essentially helps you sleep soundly - in more ways than one.

The Willis APU has been created to answer this dilemma: how to limit costly diesel engine idling in the face of recently-passed and highly-punitive engine idling regulations when drivers need to be comfortable in their working living environment? There are not currently on the market any products that successfully eliminate the need for diesel idling. In addition, the impending onslaught of regulations will unintentionally eliminate drivers' abilities to be comfortable because of the limitations of currently-available products. Finally at a time when driver turnover is very high and costly, how can industry players successfully recruit and retain experienced drivers who rightfully demand that trucks be comfortable?

The Willis is unique in the industry in that when used in conjunction with an air starter it does not add much weight to the truck. The Willis design is innovative in the trucking industry and draws heavily on techniques used in the aviation industry.
