tru -- ARB approves the Carrier EES diesel particulate filter for TRUs (reefers) Posted: 27 Nov 2013 12:22:56
The California Air Resources Board has conditionally verified the Carrier Transicold EES as a Level 3+ Diesel Emission Control Strategy. Carrier Transicold’s Engine Emissions System (EES) has been conditionally verified as a Level 3 Plus diesel emission control strategy for certain transport refrigeration units (TRU). Level 3 Plus means the EES reduces particulate matter (PM) emissions by 85 percent or more without increasing NO2 emissions more than 20 percent of NOx. A conditional verification is equivalent to verification for the purposes of satisfying the requirements of in-use emission control regulations and allows Carrier Transicold to begin marketing and selling the EES while the final details of verification are completed. The Carrier EES is conditionally verified for use on Carrier X4-7300 and 7500 TRUs, Vector 8500 and 8600MT TRUs, and Carrier UG and RG TRU generator sets equipped with model year 2012, 2013, and 2014 Kubota model V2203L-DI-EF01e engines rated at less than 25 horsepower. In-use TRU engines must have less than 3,000 hours of operation at time of installation. New TRUs may be retrofit with the Carrier EES concurrent with sale or lease. The Carrier EES uses an automatic filter regeneration system to oxidize the collected diesel soot and control engine backpressure to within the engine manufacture’s specifications. The regeneration system uses an engine intake air control valve, a diesel fuel doser, an oxidation catalyst, and a catalyzed silicon carbide wall-flow filter with an electronic control unit to achieve backpressure control. Specific conditions for which the Carrier EES has been conditionally approved may be found in ARB’s Verification Letter on the ARB's Verification Procedure website under the Carrier EES product name within the next week.

Background: TRUs are refrigeration systems powered by integral diesel internal combustion engines designed to control the environment of temperature-sensitive products that are transported in trucks, trailers, shipping containers, and railcars. The emissions from these units are a source of unhealthful air pollutants including particulate matter, toxic air contaminants, nitrogen oxides, carbon monoxide, and hydrocarbons, that all pose a potential threat to both public health and the environment. These units often congregate in large numbers at California distribution centers, grocery stores, and other facilities where they run for extended periods of time to ensure their perishable contents remain cold or frozen. These distribution and loading facilities are often in close proximity to schools, hospitals, and residential neighborhoods. In 2004, the TRU Airborne Toxic Control Measure (ATCM) was adopted by the Board to reduce diesel particulate matter emissions from TRUs and TRU gen set engines. Amendments were adopted by the Board in November 2010 and October 2011.
