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

Kenworth Clean Power may enhance fuel economy by as much as 8% for customers with high-idling times, the company says. The system comes factory-installed with 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.

Kenworth Clean Power uses deep-cycle batteries that power a thermal storage cooler with 21,000 BTUs of cooling capacity. The system is designed 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 located near the bunk, the company says.
