Utility adds door sensor for integrated reefers
Utility Trailer Manufacturing recently introduced a door switch sensor option for 3000R refrigerated trailers equipped with a Cargobull transport refrigeration unit (TRU).
The new door sensor features a switch hidden in the trailer’s stainless steel buck plate and an integrated magnet in the rear swing Barrier Door or on a rollup door, Utility reported. The contact between the switch and magnet when the door is securely closed ensures the unit maintains thermal efficiency.
“Door switches installed on the exterior door are prone to damage when pulling into docks,” Steve Bennett, Utility president and COO, said in a news release. “This often leads to corrosion, becomes inoperable, and requires maintenance. The unobstructed location of our new door sensor prevents those issues.
“Effective door sensors and receiving alerts when doors are open are critical when protecting payload that requires consistent temperature monitoring.”
The sensor is one of Utility’s trailer-integration offerings that works 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 it shuts off the TRU for more fuel-efficient operation.
