Carrier Transicold's new, engineless 40XR and 50XR truck refrigeration units are more efficient, reliable and sustainable, the company says. 

The new XR series units provide improved air management and increased air flow, the company says. 

"The R in XR represents refinements we've made inside and outside to deliver greater performance and reliability," Product Manager Scott Parker says. "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."

Parker says the units also use the new R-452A refrigerant, which has about half the global warming potential of R-404A, the refrigerant used in previous models. 

The 40XR has an on-road capacity of 14,500 BTU/hour and is designed for boxes 12-18 feet long. The model 50XR is for trucks with trailers up to 20 feet long and provides 17,000 BTU/hour on the road. Both models also have improved electric standby operations and their direct-drive units are powered by the truck's engine, eliminating the weight and costs associated with a separate engine for the refrigeration unit. 

Carrier Transicold's direct-drive truck units are split systems. The condenser is nose-mounted to the truck box over the cab and the evaporator has an extra-flat, space-saving design to maximize cargo area. The unit can be operated from the cab via the Cab Command 2 digital control.
