Carrier Transicold has received full verification for its optional engine emissions system (EES) from the California Air Resources Board (CARB) as a Level 3+ verified diesel emission control (VDEC) device.

The company said this full verification” validates the EES as an evergreen compliance solution for CARB’s particulate emissions standard for transport refrigeration units (TRUs) used in California.”

“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 & product management, Carrier Transicold.

Last November, CARB granted conditional verification to the EES, allowing its installation on the X4 Series models 7500 and 7300 and hybrid Vector 8500 and 8600MT TRUs and PowerLINE generator sets with up to 3,000 hours of engine operation.

Achieving full verification removes the 3,000-hour condition, permitting EES installation regardless of accrued hours of operation on those models.

“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 said.

“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,” he continued.

Kiefer noted that Carrier Transicold will next evaluate application of the EES to its older legacy platforms “for which maintaining CARB compliance has been limited to engine upgrades that will soon no longer be a compliance option.”
