Utility Trailer, Cargobull upgrade TRUs

Utility Trailer and Cargobull North America have launched the latest upgrade to the ultra-low emission transport refrigeration units (TRUs): a newly designed TRU with microchannel condenser and radiator that is now available on all new units.

The advanced microchannel condenser and radiator are set to significantly enhance efficiency, increase output, and elevate the overall performance of the 625 and 655MT Hybrid Transport Refrigeration Units (TRU), according to Utility. These units already comply with the stringent 2030 emissions standards and will now feature the microchannel condenser as a standard component.

Thanks to its compact and lightweight design, the condenser integrates more easily into the TRUs, improving airflow and system layout and simplifying maintenance. By reducing the refrigerant charge by three pounds (1.3kg), the microchannel condenser supports sustainability while also cutting both upfront and replacement costs.

Despite its smaller size, it delivers superior heat transfer performance, boosting the already impressive cooling capacity, the company added. Combined with Cargobull’s variable-speed engine control, the system ensures consistent and optimal thermal performance.

“The microchannel condenser boosts thermal efficiency, ensuring our 3000R refrigerated trailers maintain peak cooling performance even in high ambient temperatures,” said Steve Bennett, president & COO for Utility Trailer. “Its ability to perform reliably in extreme conditions is essential for continuous refrigeration.”

The Cargobull 625 and 655MT TRUs are both certified by the California Air Resources Board as Ultra-Low-Emission TRU Evergreen models. These advanced units come standard with integrated hybrid shore power and are exclusively available on Utility Trailer 3000R refrigerated trailers.

As a new added option, the Cargobull 620 Hybrid (Single-Temp) TRU delivers strong energy efficiency but does not fully meet ULETRU certification criteria. However, embedded shore power can be added as an optional feature.
