Key takeaways

  • Utility’s hybrid TRUs deliver up to 20% more cooling at –20°F, improving temperature control and consistency for fleets.
  • Sealed two-stage compressors and microchannel condensers reduce maintenance needs and lower the total cost of ownership.
  • Optional ePTO allows TRUs to run electrically with compatible tractors, boosting efficiency without high-voltage batteries.

NASHVILLE—Utility Trailer Manufacturing Co. has launched its next‑generation hybrid TRUs, developed exclusively for the thermally-efficient 3000R, company representatives detailed at the Technology & Maintenance Council 2026 Annual Meeting and Transportation Technology Exhibition here this week.

Strengthened by the latest advancements in Cargobull transport refrigeration technology, the new Cargobull 625+ Mono-Temp Hybrid and 655MT+ Multi-Temp Hybrid TRUs are designed to deliver a major leap forward in cooling performance, efficiency, and sustainability for North American fleets.

Utility developed the advanced Cargobull 625+ and 655MT+ Hybrid TRUs using proven ultra‑low‑emission hybrid technology. These next‑generation units feature a newly developed hermetic two‑stage compressor integrated into a compact, sealed assembly with no shaft seal, significantly reducing potential refrigerant loss and improving long‑term reliability. Complementing this is Cargobull’s cutting‑edge microchannel condenser, which enhances heat transfer for faster, more energy‑efficient cooling.

With up to 20% more cooling capacity at negative-20 degrees Fahrenheit, the new Hybrid TRUs can pull down to colder temperatures more quickly and maintain them more consistently across all operating conditions, including deep‑frozen applications. The sealed design further reduces maintenance needs, lowering the total cost of ownership for fleets. The TRUs are further enhanced by an advanced BCU (Body Control Unit) telematics system that tracks operational performance, maximizes uptime, and streamlines fleet management workflows.

“It also means there's less noise,” noted Andreas Schmitz, CEO of Schmitz Cargobull AG, speaking from the Utility Trailer exhibit. “So it's not surprising that the supermarkets are liking our units.”

The TRUs also offer enhanced flexibility through an optional ePTO (electric power take‑off). When paired with a compatible electric tractor, the ePTO enables the TRU to operate electrically, improving energy efficiency and reducing fuel consumption. This design eliminates the need for a high‑voltage battery system or e‑axle on the trailer, reducing upfront investment while increasing reliability.

“We will see more and more electric trucks coming and, by the way, I think they're going to come because they will be cheaper to run, not because of some subsidies, like they do in Europe,” Schmitz said.

When installed on the 3000R, the Cargobull 625+ and 655MT+ TRUs take full advantage of the trailer’s optimized insulation, efficient airflow design, and proven structural durability. Together, they form a fully integrated refrigerated transport solution engineered for stronger temperature control, improved fuel efficiency, and exceptional long‑term performance.

“This technology marks a major milestone in refrigerated transport,” said Steve Bennett, president and COO for Utility. “By integrating advanced hybrid TRUs with the proven performance of the 3000R, we’re giving fleets a smarter, more efficient, and more sustainable way to protect their temperature‑controlled cargo. It’s a leap forward that delivers real‑world benefits from day one.”
