Isuzu Commercial Truck of America has begun development of an all-electric Isuzu NRR EV truck integrated with the Thermo King e300 all-electric transport refrigeration unit.
Isuzu’s NRR EV was announced in March 2023 and is planned for production this summer. The Class 5 NRR EV is Isuzu’s next generation of medium-duty delivery trucks.
“Our new NRR EV has been the top conversation for the last couple of years,” Shaun Skinner, president of Isuzu Commercial Truck of America, said. “We knew we had a good solution for dry product delivery, but many of our customers also needed refrigerated delivery. With all of the intricacies of the powertrain and a new approach to refrigeration, this really shows the power of the Isuzu-Thermo King collaboration. Engineers have worked tirelessly to get this right and customers will appreciate what this truck can do. For Isuzu, this is among the first Class 5 all-electric refrigerated truck offerings, and it will open new doors for us and our brand.”
The NRR EV has three wheelbase offerings (132.5”, 150”, and 176”) that allow customers to choose between 14-20’ bodies to utilize the vehicle’s 19,500 GVWR. When it comes to the powertrain, the NRR EV can be equipped with one of four battery pack configurations (60 kWh, 100 kWh, 140 kWh, and 180 kWh) with different estimated ranges from 60-235 miles.

This advanced Isuzu powertrain is key to the development of an all-electric refrigerated Class 5 truck. The powertrain is equipped with an electric-power takeoff that has an operating range from 7-12 kWh output with a peak output of 26 kWh for demand spikes, like when operating a dump body under heavy load. One of the best features of the ePTO is that it works seamlessly without a switch. This means the driver doesn’t need to dial it up or down to meet the power demands of the onboard equipment. The NRR EV’s onboard computer will communicate directly with the Thermo King e300 all-electric transport refrigeration unit and supply the power needed.
The Thermo King e300 is part of the evolve portfolio of electrified refrigeration solutions. This Class 5 refrigerated truck solution developed by Thermo King is fully integrated into the OEM’s electric vehicle chassis. It can provide cooling for single-temperature applications with minimal impact on the Isuzu NRR-EV’s range.
The e300’s electric reciprocating compressor provides constant, continuous system capacity regardless of whether the vehicle is stationary or driving down the road. The capacity is not susceptible to varying engine RPM changes that impact a traditional engine-driven system’s performance.
The e300 eliminates traditional components like the belt-driven compressor, mount and drive kit, and refrigeration hose. Installers will appreciate the reduction in overall installation time, while owners will appreciate the increased reliability because fewer parts mean fewer breakdowns. The e300 also uses R-452A refrigerant, which is a low-global warming potential refrigerant that reduces direct CO2 emissions by nearly 50% per unit when compared to the traditional R-404A refrigerant.
