Heat Pump AntiFreeze Valve

The Inta Zero is a unique anti-freeze valve designed and engineered to protect heat pump systems that are operating with water.

Designed to discharge when the system water temperature drops to 3°C, preventing ice from forming in the heat pump circuit that could cause a breakdown or costly damage to the system.
