Supco SL25581 Defrost Thermostat W10225581

The Supco SL25581 Defrost Thermostat W10225581 is a temperature-regulating control used in refrigeration and cooling equipment to manage defrost operation based on evaporator temperature conditions. It features a tube-mount configuration with temperature-responsive switching that opens and closes the circuit during frost removal cycles. In HVAC systems it is applied in refrigerators, freezers and similar cooling units where evaporator temperature monitoring is necessary to control frost buildup on coil surfaces. The thermostat responds automatically to changing temperatures, supporting proper airflow condition and maintaining balanced cooling operation in compatible refrigeration equipment.
