Carrier Transicold is demonstrating a new zero-emission electric truck refrigeration unit in the form of the Supra.
The system will offer a range and refrigeration capacity similar to those currently seen with diesel-powered equipment, the company says. It can be used on a battery-electric vehicle or run on an engine-driven truck.
Like Carrier Transicold’s Vector trailer refrigeration system, the electric Supra uses an all-electric architecture known as E-Drive.
Eliminating the emissions and noise traditionally associated with engine-driven systems, it uses an electric evaporator and condenser fans and a sealed electric compressor. That eliminates typical service items such as belts, pulleys and shaft seals, Carrier Transicold says.
The Supra also uses R-452A refrigerant, which has a global warming potential (GWP) that’s 45% lower than today’s standard refrigerant.
The equipment emerges as California fleets face requirements to convert 15% of refrigerated trucks to zero-emission technologies by the end of 2023. The California Air Resources Board (CARB) will also require new transport refrigeration units to use refrigerants with the GWP lower than 2,200.
