Carrier Transicold unveiled plans for Supra zero-emission truck refrigeration technology, due for release by 2023. According to Carrier Transicold, the engineless Supra technology will be applied to battery electric vehicles (BEVs) or to run autonomously with conventional engine-driven trucks. It is particularly targeted toward fleets in California that must introduce zero-emissions truck refrigeration units into their fleets by the end of 2023 in compliance with proposed California Air Resources Board (CARB) requirements.
“The Supra zero-emission design completely removes the diesel engine from the equation,” said Scott Parker, product manager for truck products for Carrier Transicold. “It takes advantage of many of the system design, performance and efficiency enhancements that we recently introduced with our diesel-powered Supra series platform. As we upgraded our Supra line, we had an eye on the future, anticipating that the road ahead would require more sustainable, zero-emission technologies.”
Like Carrier Transicold’s Vector trailer refrigeration systems, the electric Supra unit uses E-Drive technology, an all-electric refrigeration architecture. The electric Supra unit requires a direct-current (DC) power supply. In the case of a non-electric truck this can be a dedicated battery module, and in BEV applications the electric Supra unit can draw energy from the truck’s battery pack.
Additional features and benefits of the Supra zero-emission design, according to the company include:
- Efficient zero-emissions performance – Utilizing a direct-current electric power source, the unit eliminates fuel consumption, emissions and noise associated with engine-driven systems.
- Maximum Range and High Capacity – The unit is being designed for full-day’s use with refrigeration performance on par with conventional diesel systems.
- Reduced service requirements – E-Drive technology uses maintenance-free electric evaporator and condenser fans and a sealed electric compressor, eliminating many typical serviceable items, such as belts, pulleys and shaft seals.
- More environmentally sustainable refrigerant – Using R-452A, with a global warming potential (GWP) that is 45% lower than today’s standard refrigerant, the electric Supra would meet CARB’s pending requirement that new transport refrigeration units use refrigerants with a GWP lower than 2,200 beginning in 2023.
