Delivering greater versatility along with quiet, emissions-free performance, Carrier Transicold is rolling out two single-temperature electric truck refrigeration units this year as the foundation of its new Supra eCool series. Carrier Transicold is a part of Carrier Global Corporation, the leading global provider of healthy, safe, sustainable and intelligent building and cold chain solutions.
The Supra eCool electric units will cover 14- to 28-foot, Class 5 to 7 straight truck applications and are designed for fleets seeking regulatory compliance or simply cleaner, more sustainable options. The engineless Supra e9 and e11 units will provide comparable refrigeration performance to Carrier Transicold’s diesel-powered Supra S8 and S10 units. Efficient performance and proprietary power management technologies optimize battery life to maximize range in support of daily delivery operations.
Supra eCool units feature:
- 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 refrigeration capacity –Designed for a full day’s use, the refrigeration performance is on par with conventional diesel systems.
- Reduced service requirements – Maintenance-free electric evaporator and condenser fans, and a sealed electric compressor reduce maintenance needs.
- More environmentally sustainable refrigerant – The unit uses R-452A, a refrigerant with a global warming potential (GWP) 45% lower than the traditional refrigerant used in transport applications.
- Lynx Fleet telematics – Carrier Transicold’s industry-leading telematics solution is factory installed for remote monitoring of temperatures, location, movement, battery state of charge and system operating performance.
In BEV applications, the Supra eCool interface provides a high-voltage interlock with the vehicle’s battery and communicates to the vehicle using a proprietary CAN bus system.
For applications where a separate power source is required, Carrier Transicold has developed a 38-kWh high-voltage DC power pack with a built-in water-cooled temperature management system. The power pack uses a high-power DC fast-charging system.
The Supra eCool design includes a variable-speed electric scroll compressor and an electronic expansion valve in the evaporator, which help to extend the operating range by more precisely and efficiently matching power draw from the battery to the cooling need at hand.
Commercial availability in North America is slated for later this year.
