Carrier’s Refrigeration Emissions System Receives CARB Verification

Carrier Transicold’s engine emissions-system option for refrigeration units received verification from the California Air Resources Board.

The company’s engine emissions system is a Level 3-verified, diesel-emission control device. The system filters exhaust with a catalytic diesel particulate filter and removes 98% of particulate matter, according to the company.

The system also filters more than 93% of hydrocarbons using a diesel oxidation catalyst, higher than the 85% requirement by CARB’s ultra-low emissions requirement for transport refrigeration units.

“Carrier Tranicold worked closely with CARB staff to advance the EES to ensure reliable emissions reduction on models equipped with Tier 4 engines and achieve full verification. Building on this achievement, Carrier Transicold will next evaluate application of the EES to our older legacy platforms, for which maintaining CARB compliance has been limited to engine upgrades that will soon no longer be a compliance option,” David Kiefer, Carrier Transicold’s director of sales, marketing and product management, said in a statement.

The system uses passive, active and active-assist regeneration to clean accumulated soot without operator intervention, according to Carrier.
