The 28mm Anti Freeze Valve from Midbrass is a simple yet highly effective solution for protecting water-based air source heat pump systems from freezing.
Automatically activating when temperatures drop below 3°C, the valve releases water to prevent ice formation, safeguarding your system from costly damage.
Built from durable DZR brass with large 28mm compression fittings, it’s easy to install and ideal for non-glycol-based systems.
