LOUISVILLE, Ky. (March 20, 2007) - The ComfortGuard™ APU system from Cummins features ComfortGuard Cab Air HVAC components for high-performance heating and cooling. The easy-to-use in-cab thermostat can be controlled manually or programmed to start automatically based on thermostat settings or time of day. The complete and compact system offers an effective solution for heating and cooling the cab with the main engine off.


For cooling, the ComfortGuard Cab Air system's 12,000-Btu capacity space-saving evaporator section mounts under the bunk and delivers up to 350 cubic feet per minute of cool, comfortable air. When the 4,000/8,000-Btu two-stage electric heat function is selected on the wall thermostat, it quickly warms the cab in subzero temperatures. Unlike competitive systems, 120-volt power remains available from the APU receptacles for powering other loads while the heating and cooling system runs at full capacity.


The ComfortGuard Cab Air installation kit includes quick-connect pre-charged line sets so the system installer doesn't have to evacuate or charge the system. All the electrical connections are design-mated to the ComfortGuard auxiliary power unit (APU) for true "plug-and-play" installation. The installation kit also includes registers, ductwork and mounting templates - everything necessary to install the unit. The ComfortGuard system's unique plug-and-play design reduces the cost of installation by up to one-half. Quick disconnects, pre-charged A/C lines and compact dimensions allow system installation on most trucks in about a day.


Unlike other units that have to be mounted vertically, limiting installation options, the ComfortGuard Cab Air condenser can be mounted in any orientation. Upside down, right side up or lying on its back, it still delivers cool air which makes installation flexible and customizable for every truck in the fleet. The system can be installed and serviced throughout the U.S. and Canada by the extensive network of Cummins distributors and authorized dealer service locations.
