CARB approves new Carrier Transicold retrofit system for reefers

The California Air Resources Board has granted conditional approval of a new emissions system for reefer units.

In an announcement posted on CARB’s website, the air quality agency said Carrier Transicold’s Engine Emissions System has been conditionally verified as a Level 3 Plus diesel emission control strategy. The system can be retrofitted on Carrier x4-7300 and 7500 reefers, Vector 8500 and 8600 MT reefers, and Carrier UG and RG generator sets with model year 2012, 2013 and 2014 Kubota model V2203L-31-EF01e engines rated at less than 25 horsepower.

To meet CARB’s standards, the retrofits can be placed only on units with 3,000 hours of operation or less at the time of installation.

CARB says the Carrier EES system uses an automatic filter regeneration system that oxidizes diesel soot to control engine backpressure. 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 perform back pressure control.
