Supco SFPC Freeze Protection 50°F Open 35°F Close

The Supco SFPC Freeze Protection Control is a component that prevents air conditioning evaporator coils from freezing. This part opens at 35°F and closes at 50°F using a Single Pole Single Throw switch. It has 12" leads, fits tubing up to 7/8" in diameter and can support currents of 5A to 10A depending on voltage. That is used widely in residential and commercial HVAC systems to protect the coils from freeze damage, reduce maintenance, and prolong the equipment longevity. This small, rugged design for its durable performance is essential to cold climate applications.
