ComfortPro™ APU Now CARB Compliant

Feb 16, 2009

ATHENS, Ga., United States

The new ClearSky™ diesel particulate filter (DPF) has been conditionally verified by the California Air Resources Board (CARB) for use with Carrier Transicold’s ComfortPro™ auxiliary power unit (APU). Verification allows operators of Class 8 tractors with 2007 or newer engines to use Carrier APUs with the ClearSky DPF throughout the Golden State. Carrier Transicold is part of Carrier Corp., a business unit of United Technologies Corp. (NYSE: UTX).

Using highly efficient active-regeneration technology, the ClearSky DPF achieves CARB’s APU emission standard, which calls for particulate emissions to be reduced by at least 85 percent. It also meets CARB’s NOX (nitrogen oxide) emission regulations.

“Active regeneration technology presents unique advantages,” said Eduardo Andrade, Carrier Transicold’s business manager – Special Products. “A challenge for most APU makers is that the units typically don’t generate enough heat to burn off particulates from the exhaust. However, the ComfortPro APU’s Deltek™ hybrid diesel-electric technology is unique, and its powerful generator creates the necessary temperatures.”

With a silicon carbide filter element and an easy-to-maintain design, the ClearSky DPF replaces the ComfortPro muffler on new equipment, and it can be field installed on existing units (model PC6000). Requiring no driver intervention, the ClearSky DPF automatically regenerates in less than 25 minutes, every 10 to 30 operating hours.

Without a DPF, some truckers are now prohibited from running their diesel-powered APUs in California. The California law applies to trucks equipped with a 2007 or newer engine. Rigs with older engines may still use the ComfortPro APU without the DPF in California. And, even without the DPF, operators of newer rigs can take advantage of the ComfortPro APU’s shorepower option when parked at any California location where an adequate 110-volt power supply is available.

ComfortPro APUs help owner/operators and fleets lower vehicle emissions and save fuel by significantly reducing the need to idle the truck engine. The device provides heating, cooling, electrical power, battery charging and engine warming.
