 XR engineless TRU improves performance

USA: Carrier Transicold’s new engineless 40XR and 50XR truck refrigeration units are said to deliver improved performance and sustainability.

The new XR series units are said to provide improved air management and increased air flow resulting in faster pulldown and more uniform temperature control when compared to the X series models they succeed. Lower GWP refrigerant R452A is also used instead of R404A.

The units’ condensers have been upgraded to Carrier Transicold’s micro-channel coil design for higher-efficiency heat transfer, as well as weight savings and added durability. Condenser fans have also been enhanced with maintenance-free brushless motors for improved reliability.

The XR series units are designed for mid-sized and large trucks. The 40XR, with an on-road capacity of 14,500 Btu/hr, is designed for boxes 12ft to 18ft long. With a 17,000‑Btu/hr on-road capacity, the model 50XR is suited to trucks with a cargo area up to 20ft in length. 

Both models also have improved electric standby operation capacities compared to the models they succeed. 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 that helps to maximise the cargo area. The refrigeration unit can be operated from within the driver cab via the Cab Command 2 digital control.
