Fernox Fry Electrolytic Scale Reducer In-line scale reducer to prevent the build-up of scale using electrolytic principles. The Fernox Electrolytic Scale Reducer is not a water softener but it induces coagulation whilst the water hardness remains unchanged. It works in the same way as a small battery where the brass body (cathode) and internal zinc (anode) are connected via mains water (electrolyte) to alter the structure of the hardness salts. The effect is to enable the hardness salts to cluster together rather than attach to the heat exchanger and pipe work in a central heating system. Limescale deposits are more common where heat is generated and can have lasting damaging effects on the efficiency and life of the boiler. The Fernox Electrolytic Scale Reducer benefits a range of appliances including kettles, taps, showers and boilers.
