Scalemaster 500119 SM2 Central Heating Descaler

Sentinel X100 Inhibitor is a heavy‑duty chemical treatment designed to protect closed and indirect central heating systems from scale, corrosion and hydrogen gassing. With a pH‑neutral formula, it is safe and easy to handle, and its TripleTech Anti‑Corrosion Technology enables effective protection across multi‑metal systems such as copper, steel and aluminium without degrading components. Ideal for commissioning or retrofit work, the 1 Litre bottle treats a typical domestic system and is compatible with common metals and plastics, simplifying on‑site dosing without requiring multiple products. A test kit is available to monitor inhibitor levels over time, making it suitable for both installers and DIYers.

From a practical standpoint, the inhibitor remains in the system indefinitely once dosed; only a top‑up is required if the system is drained. It can help reduce boiler noise and provides broad compatibility with metals and plastics.
