Helping to provide increasingly sustainable choices in transport refrigeration, Carrier Transicold is introducing four new premium performance trailer refrigeration units that offer double-digit fuel efficiency improvements and lifetime compliance with emissions requirements of the California Air Resources Board (CARB), the manufacturer noted in a press release.

The new 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%.

The new units take advantage of an advanced version of the proven Kubota engine used throughout Carrier Transicold’s existing trailer platforms. Among its attributes detailed by Carrier Transicold, the new 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 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.

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 versatile Vector units feature E-Drive all-electric refrigeration architecture for efficient performance and reduced maintenance, and the X4 series delivers refrigeration capacities unsurpassed in the industry.

Carrier Transicold’s CARB-compliant TRUs help fleets significantly reduce their environmental impact, aligning with Carrier’s 2030 Environmental, Social and Governance goals of reducing customers’ carbon footprint, by an estimated 575,000 metric tons of carbon dioxide equivalent emissions per year.
