Our 48’ and 53’ tandem and sliding spread axle reefer units were certified with the California Air Resources Board (CARB) by May 1, 2009 far ahead of the July 16th deadline for out of state businesses compliance.

Continuing to apply new technology for use in the industry, we have selected to use ThermoKing Smart reefer units insuring that your load stays at the specified temperature while doing our part for the environment as well.

California Air Resources Board TRU ruling :

In 1998, California identified diesel exhaust particulate matter (PM) as a toxic air contaminant based on its potential to cause cancer, premature death, and other health problems. Diesel engines also contribute to California’s fine particulate matter (PM 2.5) air quality problems. Those most vulnerable are children whose lungs are still developing and the elderly who may have other serious health problems.

Transport Refrigeration Units (TRUs) are refrigeration systems powered by diesel internal combustion engines designed to refrigerate or heat perishable products that are transported in various containers, including semi-trailers, truck vans, shipping containers, and rail cars. Although TRU engines are relatively small, ranging from 9 to 36 horsepower, significant numbers of these engines congregate at distribution centers, truck stops, and other facilities, resulting in the potential for health risks to those that live and work nearby. Since diesel particulate matter has been identified as a toxic air contaminant, the ARB adopted an Airborne Toxic Control Measure (ATCM) for TRUs and TRU generator sets on February 26, 2004.

On January 9, 2009, U.S. EPA approved ARB’s request for authorization to enforce the TRU ATCM, also known as a waiver from preemption. This decision was published in the Federal Register on January 16, 2009 (see Federal Register, Vol. 74, No. 11, Friday January 16, 2009, Notices, pages 3030 – 3033). This decision affects not only persons in California, but also persons outside the State who would need to comply with California’s TRU ATCM regulations to enter California with TRU engines. Therefore this action has national applicability.
