How does Sentinel KalGUARD work?

Sentinel KalGUARD uses an electrolytic process to prevent limescale encrustation for commercial properties. The independently-proven technology uses electrochemical phemonena to impart a tiny amount of soluble zinc which interferes with the crystal structure of scale-forming water hardness minerals so that they cannot form a hard, tenacious scale inside pipework or appliances when the water is heated.
