The Kenworth Clean Power no-idle system is now available for order as a factory-installed option on T800 and W900 models equipped with the 72-inch AeroCab sleeper.

Kenworth Clean Power may enhance fuel economy by as much as 8 percent for customers with high-idling times. Among the system's benefits are factory installation, Kenworth warranty coverage, no-idle features, and full compliance with California Air Resources Board (CARB) idling regulations that went into effect this year for sleeper trucks with 2007 and later model engines.

The system uses dedicated, advanced deep-cycle batteries that power a thermal storage cooler with 21,000 Btus of cooling capacity. It has the capability to provide engine-off cooling and heating, plus 120-volt power for hotel loads. Once the truck is shut off, a sleeper control panel regulates the temperature range and a variable-speed fan circulates chilled air through a duct near the bunk.
