Alliance Parts, the private label brand of Freightliner LLC, has introduced the 2007 Alliance Premium Auxiliary Power Unit (APU). The Alliance Premium APU reduces pollution and complies with anti-idling laws while providing 12,000 BTUs of air conditioning, 10,000 BTUs of heating and 3,300 watts of 110 volt electricity to ensure driver comfort. Its one-cylinder engine, the only one in the industry, burns just one-tenth of a gallon of fuel an hour, saving drivers money on fuel.
The Alliance Premium APU also offers design advantages by using a free-standing system that operates independently of the factory OEM HVAC system.
