New Supra Truck Units Deliver More Powerful Refrigeration Capacities with Greater Efficiency

Three new models have been added to Carrier Transicold’s next-generation Supra™ series of diesel-powered truck refrigeration units, providing more powerful cooling choices for small to large box trucks. Joining the Supra S6 model that was introduced in 2019 are the S7, S8 and S9 models, providing solutions for trucks ranging from 10 to 28 feet in length.

Using about 50% less refrigerant, all four models provide greater cooling capacity at AHRI test points than prior models – up to 20% more, depending on model and operating conditions.

“These next-generation Supra units deliver improved capacities more efficiently, while using less fuel and refrigerant,” said Scott Parker, product manager, truck products, Carrier Transicold.

“Improved efficiency means fuel economy is significantly improved,” Parker said. “For example, a Supra S7 unit consumes about 37% less fuel than its predecessor.

When parked and operating on electric standby power, models in the new Supra series deliver refrigeration capacities that approach or are equal to their capacities when engine-driven, surpassing some competitive products, which can lose up to a quarter of their capacity when running on electric standby.”

The new design also reduces sound output relative to earlier models, making the new Supra series especially well-suited for nighttime urban deliveries. Enhancements were made to reduce service requirements and extend the oil-service interval by 33% to 2,000 hours.


The Supra series now incorporates Carrier Transicold’s sophisticated APX™ control technology with Cab Command™ control interface, providing intelligent performance optimization, automatic trip data recording and enhanced system diagnostics. It seamlessly integrates with Carrier Transicold’s eSolutions™ telematics offering, enabling remote monitoring and control of the refrigeration system, GPS location data, geofencing and many more capabilities.
