US-based OEM, Utility Trailer Manufacturing Company, has introduced a new feature for its 3000R reefer equipped with a Cargobull Transport Refrigeration Unit (TRU).
Utility has added a door switch sensor to the trailer specification. It is hidden in the 3000R stainless steel buck plate and there is also an integrated magnet either in the rear swing barrier door or on a rollup door.
The contact between the switch and the magnet when the door is securely closed is reported to ensure the 3000R maintains thermal efficiency.
“Door switches installed on the exterior door are prone to damage when pulling into docks,” said Utility President and COO, Steve Bennett.
“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.”
Last month, Utility announced the opening of a new facility.
