Sentinel X800 is a powerful cleaner developed to quickly remove iron oxides, limescale, and other stubborn deposits from old or compromised heating systems. Thanks to its TripleTech™ formula, it restores thermal efficiency by acting effectively on heat exchangers, radiators, and pipes. It is suitable for use with high-circulation flushing pumps, but also works in manual cleaning, both hot and cold. Compatible with all metals, including aluminum, it is biodegradable, non-toxic, and protects metals by preparing them for the addition of Sentinel X100 inhibitor.
