Proportional anti-limescale dispenser W-CAL

Domestic plumbing systems contain a certain amount of magnesium and calcium salts, which cause hardness. Heating water triggers a chemical process that generates calcium carbonate (limescale) and carbon dioxide. The limescale precipitates as deposits and scales all of the system's metal parts (e.g. the heat exchanger in boilers), while the carbon dioxide can have corrosive effects inside the system. W-CAL is the perfect solution for these problems! Thanks to its unique dosage system, W-CAL proportionally dissolves the polyphosphate in water, which performs a "chelating" (isolation) action on the magnesium and calcium flakes, preventing precipitation and the subsequent formation of limescale deposits. Furthermore, over time, polyphosphate tends to eliminate existing limestone deposits and provides effective corrosion protection by creating a thin protective film over the surfaces of the system

Protects boilers, heat exchangers, furnaces etc. from limescale deposits and corrosion
