Carrier Transicold debuts Supra eCool electric truck refrigeration unit series

The company notes that the Supra e9 and e11 units will provide comparable refrigeration performance to its diesel-powered predecessor.

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 notes that the 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 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, Carrier Transicold stated in a recent press release.

According to the company, Supra eCool units feature:

  • Zero-emissions performance – Utilizing a direct-current electric power source, the unit eliminates fuel consumption, emissions and noise associated with engine-driven systems.
  • 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 telematics solution is factory installed for remote monitoring of temperatures, location, movement, battery state of charge and system operating performance. (Service plan required.)

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, the company notes. For applications where a separate power source is required, the company 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. According to the company, this helps to extend the operating range by more precisely and efficiently matching power draw from the battery to the cooling need at hand.

Daimler, Linde to provide new liquid hydrogen refueling process

The companies say the process is safe, fast and simple, adding that it can of deliver 175 pounds of liquid hydrogen in 10-15 minutes.

Daimler-Linde-liquid-hydrogen-refueling-3

Daimler Truck and Linde Engineering recently announced subcooled liquid hydrogen (sLH2), a jointly developed refueling technology. According to the companies, sLH2 allows for higher storage density, greater range, faster refueling, lower costs and superior energy efficiency over gaseous hydrogen.

Daimler and Linde say the new sLH2 pump slightly increases the pressure of the liquid hydrogen, allowing a 40-ton heavy-duty truck to fill up with 175 lbs. of liquid hydrogen in about ten to fifteen minutes, supplying a range of more than 630 miles. At the same time, the companies claim the required investment for sLH2 hydrogen refueling stations are two to three times lower, and operational costs are five to six times lower.
