ATHENS, Ga. — The California Air Resources Board (CARB) has given Carrier Transicold full verification for its engine emissions system (EES) option as a level 3+ verified diesel emission control device.
“This is yet another significant milestone in the planned rollout of our latest trailer refrigeration platforms and emissions compliance devices as we continue to provide refrigerated fleets with technology options and compliance choices that best suit their particular operations,” said David Kiefer, director of sales, marketing and product management, Carrier Transicold.
Last year, CARB gave the EES a conditional verification, that allowed its installation on certain models and generator sets with up to 3,000 hours of engine operations. With full verification, the 3,000 hour condition is removed, allowing the EES installation on any of the model, regardless of the accrued hours of operation.
“CARB’s robust verification process requires independent testing and diligent review by CARB staff to assure fleets that verified products meet stringent durability, performance and emissions-reduction specifications,” Kiefer added. “Carrier Transicold 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.”
Installed as a substitute for a standard exhaust system, the EES filters exhaust using a high-performance diesel oxidation catalyst (DOC) and a catalytic diesel particulate filter (CDPF). The DOC removes more than 93% of hydrocarbons and the CDPF reduces more than 98% of particulate matter, well beyond the 85% ULETRU requirement.
No operator intervention is needed because the EES uses passive, active and active-assist regeneration to clear accumulated soot.
