Carrier Transicold debuts Supra eCool truck refrigeration

Commercial availability in North America is slated for later this year.

Carrier Transicold is rolling out two single-temperature electric truck refrigeration units this year as the foundation of its new Supra eCool series. The company says 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.

The company says that features of Supra eCool units include:

  • Utilizing a direct-current electric power source, the unit eliminates fuel consumption, emissions and noise associated with engine-driven systems.
  • Designed for a full day’s use, the refrigeration performance is on par with conventional diesel systems.
  • Maintenance-free electric evaporator and condenser fans, and a sealed electric compressor reduce maintenance needs.
  • 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 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 says it 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, the company says.

Commercial availability in North America is slated for later this year to help California fleets comply with the California Air Resources Board (CARB) deadline of Dec. 31 to convert 15% of their refrigerated trucks to zero-emission refrigeration technologies.
