NASHVILLE—Utility Trailer and Cargobull North America revealed at TMC here the latest innovations to their ultra-low emission transport refrigeration units (TRUs): a newly designed TRU with microchannel condenser and the introduction of the Load-Dividing Bulkhead as a new option.
The microchannel condenser is set to further enhance efficiency, increase output, and boost overall performance of the 625 and 655MT Hybrid TRUs, which already meet the emissions standards set for 2030 and will now become a standard feature.
The microchannel condenser features a more compact design, making it easier to integrate into the TRUs and allowing for improved airflow. Despite its size, this microchannel condenser improves heat transfer and increases the already-high cooling capacity, according to the manufacturer. With the unique Cargobull variable-speed engine control, the TRU maintains optimal thermal performance.
“Our microchannel condenser offers better thermal efficiency, ensuring optimal cooling capacity even in elevated ambient temperatures,” stated Andreas Schmitz, President and CEO of Schmitz Cargobull, designers of the units. “At high outside temperatures, the condenser maintains reliable performance, crucial for consistent refrigeration. By reducing the refrigerant charge by 3 pounds, we enhance sustainability and lower both upfront and replacement costs.”
The Cargobull 625 and 655MT TRUs are both California Air Resources Board-certified as ULETRU (ultra-low-emissions TRU) Evergreen units. Featuring additional hybrid shore power as a standard feature, these revolutionary TRUs are exclusively available on Utility Trailer 3000R reefers.
The latest option for Utility’s 3000R multi-temp reefer is the new Load-Dividing Bulkhead from Cargobull North America. This moveable, track-mounted bulkhead enhances energy efficiency and allows flexible temperature management by enabling different compartments with varying temperatures and volume capacities. The efficient sealing system forms an airtight seal, preserving optimal temperatures within compartments. This feature significantly reduces air flow and thermal transfer between compartments, optimizing thermal efficiency for partial loads.
“The partition wall is designed to be strong and reliable, eliminating the need for a mattress partition. It is easy to operate, with no shrinking during up and down movement,” Schmitz said. “The wall features automatic pressure equalization through the retraction of side and bottom seals when opening and is operated by a central locking lever. Additionally, it includes an angle-dependent brake for one-hand operation and automatically locks in the parking position, whether the wall is in the upper or lower position.”
