The KE2 Low Temp + Defrost is an ideal refrigeration controller for all-around versatility. The controller works on everything from walk-ins to under counter freezers and coolers. This eliminates the need for a separate thermostat and defrost time clock. The controller is unique for its ability to control both temperature and defrost, providing precision setpoint and temperature measurement to one-tenth of a degree. Another unique feature is the controller’s ability to incorporate door switches and other accessories.
