Supco SL10068 Defrost Thermostat

The Supco SL10068 Defrost Thermostat is a sealed bimetal temperature control used to manage defrost cycles in refrigeration evaporator assemblies. It senses coil temperature and opens or closes the electrical circuit to regulate when the defrost heater is activated and when cooling resumes. In equipment and refrigeration equipment, it is placed on evaporator coils inside freezers, refrigerators, and cooling units to prevent frost buildup that restricts airflow within HVAC systems. It works as part of the defrost control circuit along with timers and heaters to maintain consistent coil operation. The unit is commonly installed in commercial refrigeration and household cooling systems for steady temperature regulation.
