Many of the older fractional horsepower refrigeration systems, such as reach-in coolers or prep table coolers, use a mechanical constant cut-in control to regulate the air temperature within the case.

Conserve energy and cut costs with one of these editor-approved models.

Repairing reach-in coolers and freezers with electronic temperature controllers can be challenging at times. Some failures are easy to troubleshoot and repair, but others can be frustrating. For ...
