ANTIFREEZE VALVE-CIMBERIO
The Cimberio CIM 138 Antifreeze Valve is engineered to protect heat pump systems from freeze damage. When the circulating fluid’s temperature drops close to freezing (around 3 °C), this valve automatically opens to drain a small amount of fluid, preventing freeze-induced pipe bursts.
Ideal for installations in cold climates, it ensures operational reliability and helps avoid costly repairs.
