The California Air Resources Board has given conditional verification to Carrier Transicold’s new optional engine emissions system (EES). The EES is capable of reducing diesel particulate mass from refrigeration exhaust by more than 98%.
Carrier reefer engines were already certified for “evergreen” compliance for engines less than 25hp in all of North America, except California. California green laws state that a verified diesel emissions control (VDEC) strategy be applied to units in the 25hp class for use in the state after the first seven years. Now, Carrier Transicold is said to be the first OEM-developed CARB level-3-plus VDEC for trailer refrigeration units, available with initial purchase or as a later add-on.
The EES is certified for use in the X4 Series single-temperature models 7500 and 7300, and the hybrid Vector 8500 single-temperature and Vector 8600 multi-temperature units. According to Carrier, the EES can be factory equipped at time of purchase or installed later, as long as there are less than 3000 hours of engine operation.
