As the number one selling reefer in North America for more than 30 years, the 3000R continues to maximize performance and optimize thermal efficiency. Among Utility Trailer’s latest innovations is a new door switch option for 3000R refrigerated trailers with Cargobull transport refrigeration units (TRUs).

The new door sensor features a switch hidden in the 3000R stainless steel buck plate and an integrated magnet in the rear swing Barrier Door® or on a roll-up door. The contact between the switch and magnet when the door is securely closed ensures the 3000R maintains thermal efficiency.

“Door switches installed on the exterior door are prone to damage when pulling into docks. This often leads to corrosion or other issues requiring maintenance and repairs. The unobstructed location of our new door sensor prevents those issues.” Utility Trailer President and COO Steve Bennett said. “Effective door sensors and open door alerts are critical when protecting payloads that require consistent temperature monitoring.”

The unique-design door sensor is one of Utility’s trailer integration offerings that work with the Cargobull TRU, an exclusive option for the 3000R. With the new door sensor, drivers are alerted if doors are open when pulling away from docks or shuts off the TRU for more fuel-efficient operation.
