LOUISVILLE, Ky. — Cummins today introduced the ComfortGuard system – an integrated cab heating and cooling system that saves fuel and reduces emissions.

Cummins ComfortGuard is fully integrated with the vehicle’s heating/ventilation/ air-conditioning (HVAC) system, so that the vehicle’s main engine does not have to be running to provide heating and cooling for the cab. The ComfortGuard idle-reduction capability is provided by a two-cylinder diesel engine and an Onan genset, which has been a mainstay of the RV and Marine markets for years.

“ComfortGuard is part of Cummins commitment to customers to achieve the lowest operating costs while providing measurable environmental benefits,” said Cummins Executive Director – Marketing Tom Kieffer. “In addition to reducing idle time, the Cummins ComfortGuard system will provide the end user with up to an eight and one-half percent fuel economy improvement, based on 2,000 hours of operation in a 12-month period. ComfortGuard is able to do this while providing outstanding cab heating or cooling because it is fully integrated with the vehicle manufacturer’s HVAC system.”

The ComfortGuard system also allows end users to operate computers, microwaves and other electronic devices with its 12-volt DC and 120-volt AC auxiliary power.
ComfortGuard will be available in early 2005.
