Carrier Transicold is introducing four premium performance trailer refrigeration units that offer double-digit fuel efficiency improvements and lifetime compliance with emissions requirements of the California Air Resources Board, according to the company.

The systems include two single-temperature units, the Vector 8700 and X4 7700, and two multi-temperature units, the Vector 8800MT and Vector 8811MT. All reduce particulate emissions by 96% compared to current offerings and, depending on the application, improve fuel efficiency from 5%−20%, Carrier Transicold officials said in a press release.

The units will be available for order later this year for delivery in 2023, which will help fleets operating in California that will be adding units next year and will be subject to CARB’s newly amended Airborne Toxic Control Measure for transport refrigeration units, officials said.

The units take advantage of an advanced version of the Kubota engine used throughout Carrier Transicold’s existing trailer platforms. Among its attributes, the 24-hp smart engine:

• Features clean engine technologies, including common-rail fuel injection, an enhanced fuel filtration system and diesel oxidation catalyst that push particulate, hydrocarbon and NOx emissions to new lows.

• Provides lifetime regulatory compliance with the Environmental Protection Agency’s Tier 4 emission standards and CARB’s stricter ATCM for TRUs that takes effect May 31, 2023.

• Achieves double-digit fuel economy thanks to optimized fuel-delivery from common rail fuel injection and the introduction of a third engine speed, called “eco speed,” that automatically drops engine RPMs below low speed when conditions permit, to help boost fuel efficiency.

“Our premium performance units do not require complex exhaust gas recirculation to achieve emissions targets,” said Steven McDonald, trailer product manager, Truck Trailer Americas. “Unlimited CARB compliance means no add-on exhaust treatments are ever required, based on the current regulation.”

All four models also use R 452A, a CARB-compliant, new-generation refrigerant with a global warming potential 45% lower than that of the traditional TRU refrigerant, R 404A. Additionally, all are equipped with Carrier Transicold’s telematics solution for remote monitoring of temperatures, location, movement and system operating performance. To help maintain battery charge supporting the unit and its telematics system, Carrier Transicold now also offers its TRU-Mount solar panel as a factory-installed option.

Carrier Transicold’s Vector units feature E-Drive all-electric refrigeration architecture.
