INTA ZERO - ANTI-FREEZE VALVE 28MM

Inta Zero Anti‑Freeze Valve – Protects Heat Pump & Water Systems

The Inta Zero Anti‑Freeze Valve is a specialist safety device engineered to protect heat pump and hydronic heating systems operating with water from freeze‑related damage. When water temperatures drop to around 3 °C, the valve automatically discharges to prevent ice forming in sensitive circuit components  a common cause of breakdowns, costly repairs, and system downtime in cold environments.

Ideal for ground‑source, air‑source, and hybrid heat pump installations, as well as other closed‑loop hydronic systems, the Inta Zero adds an extra layer of protection that every installer can specify with confidence in climates where freezing conditions may occur.

Why You Should Buy This Valve

✔ Freeze Protection for Heat Pumps – Automatically activates at low water temperatures to prevent ice damage.
✔ Reduces Risk of Costly Breakdowns – Protects heat pump compressors, pipes, pumps, and heat exchangers from freeze stress.
✔ Automatic Operation – No manual intervention required — the valve responds to water temperature changes.
✔ Installer Confidence – Designed for integration into water‑based heating and renewable systems without complex controls.
✔ Peace of Mind – Ideal for external plant rooms, poorly heated spaces, or cold weather environments where frost risk is high.
