Scalemaster^® Electrolytic Limescale Inhibitors prevent limescale build-up by adding a small trace of zinc to the water. This has the effect of suppressing limescale formation by bonding to the dissolved calcium ions which then require more energy for precipitation. Any micro-crystals which do form provide nucleation sites (seed crystals) where general bulk precipitation occurs. Limesale crystals which form are then washed away by the water flow rather than adhering to heat-exchange surfaces.

Laboratory research has shown a relationship between the amount of zinc dissolved and the reduction in limescale precipitation achieved. Scalemaster^® Electrolytic Limescale Inhibitors incorporate patented technology to boost the supply of zinc. In independent tests, application of the Scalemaster^® electrolytic technology typically extends boiler life by 50% in hardwater areas by preventing limescale precipitation.

Scalemaster^® Electrolytic Limescale Inhibitors are suitable for treatment of the whole house and individual appliances (especially showers).
