CARB gives conditional OK to emissions reduction system

Carrier Transicold announced that its optional engine emissions system (EES) has received conditional verification from the California Air Resources Board (CARB). The EES reduces diesel particulates from trailer refrigeration units by more than 98%, Carrier Transicold said.

According to Carrier Transicold, the EES is the first OEM-developed CARB level 3+ verified diesel emissions control (VDEC) device for trailer refrigeration units that can be included with initial purchase or added later for users who do not initially require it. A Level 3+ VDEC device reduces particulate emissions in accordance with CARB’s ultra-low emissions requirement for transport refrigeration units, also known as ULETRU, while also reducing nitrogen oxides.

“Carrier Transicold’s latest trailer refrigeration unit engines are already certified for ‘evergreen’ compliance with the 2013 EPA Tier 4 standard for engines less than 25 hp., allowing for indefinite use throughout North America, except in California,” said David Kiefer, director of marketing and product management, Carrier Transicold. “In California, CARB uniquely requires that a VDEC strategy be applied to units in this horsepower class for use in the state beyond the initial seven years.”

The EES is conditionally verified for use with Carrier Transicold’s new Tier 4-compliant designs, which include the X4 Series single-temperature models 7500 and 7300, and the hybrid Vector 8500 single-temperature and Vector 8600MT multi-temperature units. In the current phase of the verification process, these Carrier Transicold units may be factory-equipped with the EES, and the EES can be installed on previously purchased units with up to 3,000 hours of engine operation.

“CARB conditional verification validates the operation and effectiveness of the EES in Carrier’s 2013 Tier 4 refrigeration units,” Kiefer said. “This is a major milestone. It is the first and biggest step toward offering a broader array of CARB-compliant options to our customers.”
