The Trappex Anti-Freeze Valve is an essential protection component specifically designed for heat source pump systems. In cold weather, when temperatures drop to 3°C or below, this valve automatically opens the flow and return circuit to prevent ice formation, safeguarding the system from potential damage and breakdown.
 
Made from robust and durable materials, the 28mm valve provides a low-cost alternative to glycol-based fluids, eliminating the need for annual maintenance or topping up. Easy to install, it ensures reliable performance and long-term protection for heat source pump systems.
