The Caleffi DN 25 (1 inch) anti-freeze valve is an element that protects the heat pump system against the effects of low temperatures. The device reacts to a drop in the medium temperature, opening at 3 °C and thus preventing water in the system from freezing. The valve closes automatically when the medium reaches 4 °C. The component is designed for continuous operation in an ambient temperature environment from -30 to 60 °C.
