Carrier Transicold’s new, engineless 40XR and 50XR truck refrigeration units are aimed at enhancing efficiency in local and regional deliveries by grocery, food service, produce, and pharmaceutical businesses.

According to Carrier, along with contemporary aesthetics, the new XR series units provide improved air management and increased airflow, resulting in faster pulldown and more uniform temperature control compared to the X series models.

“The R in XR represents refinements we’ve made inside and outside to deliver greater performance and reliability,” said Scott Parker, product manager, Truck Products, Carrier Transicold. “For example, the unit condensers have been upgraded to our proven microchannel coil design for higher-efficiency heat transfer, weight savings, and added durability. Condenser fans have been enhanced with maintenance-free brushless motors for better reliability.”

Detailing the XR Series from Carrier

The XR series units are designed for mid-sized and large trucks. Looking at the two models, a few differences include: 

  • The 40XR, with an on-road capacity of 14,500 BTU/hour, is designed for boxes 12 to 18 feet long.
  • With a 17,000-BTU/hour on-road capacity, the model 50XR is well-suited to trucks with a cargo area up to 20 feet long.

Both models also have improved electric standby operation capacities compared to the models they succeeded, according to Carrier. As direct-drive units, their belt-driven refrigerant compressors are powered by the truck engine, eliminating the weight and costs associated with having a separate engine for the refrigeration unit.

Carrier Transicold direct-drive truck units are split systems in which the condenser is nose-mounted to the truck box over the cab, and the evaporator is attached to the ceiling of the cargo area. Carrier Transicold’s SlimLINE evaporator has an extra-flat, space-saving design, which it notes helps maximize the cargo area.

The refrigeration unit can be operated from within the driver cab via the Cab Command 2 digital control.

“Sustainability is also improved when using the next-generation refrigerant R-452A, which has about half the global warming potential of R-404A, the refrigerant used with the prior models,” Parker added. “Plus, due to efficiency gains, the required refrigerant is reduced by more than 20%.”

Carrier Transicold’s new XR series of engineless truck refrigeration units support Carrier’s aim to reduce its customers’ carbon footprint by more than one gigaton as part of its 2030 Environmental, Social, and Governance goals.
