Sentinel X100 inhibitor provides protection for clean central heating systems against lime scale and corrosion. Suitable for use in all types of indirect central heating system, Sentinel X100 inhibitor will extend the life of the system, ensuring maximum efficiency and minimizing fuel usage. Limescale and corrosion are the two main causes of central heating inefficiency, leading to radiator cold spots, boiler inefficiency, a noisy system and a multitude of other problems. Once a system has been prepared using one of the cleaners from the Sentinel cleaning range, it should be protected with Sentinel X100 Inhibitor to prevent the occurrence of lime scale build up or corrosion. Sentinel X100 inhibitor has TripleTech anti-corrosion technology, a unique blend of heavy-duty specialist corrosion inhibitors. Since central heating systems are normally made up of a variety of metals, each of these specialist inhibitors provides protection for different metals for unrivalled performance in protecting multi-metal central heating systems.
