Carrier Transicold is bringing to market two engineless truck refrigeration units (TRUs) for local and regional deliveries of temperature-controlled products such as groceries and pharmaceuticals.

The 40XR and 50XR units offer improved air management and increased air flow for faster pulldown and more uniform temperature control than previous X-series models, the company claims.

“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, as well as weight savings and added durability. Condenser fans have been enhanced with maintenance-free brushless motors for better reliability.”

The XR units are designed for mid-sized and large trucks. The 40XR has an on-road capacity of 14,500 BTU/hour for boxes 12-18 feet long. The 50XR has 17,000 BTU/hr on-road capabilities for trucks with cargo areas of up to 20 feet long.

They both have electric standby capabilities. The direct drive units have belt-driven refrigerant compressors powered by the truck engine, reducing weight and costs associated with standalone TRUs.
