Abstract: A variable resonance descaling decalcifier device for the treatment of hard, very hard and low hardness water is provided. The device works effectively and efficiently for line frequencies in the range between 30 hertz and 400 hertz. The device includes a resonator portion and a transformer portion. The resonator portion includes four coils (L1, L2-1, L2-2, L3) which surround a pipe (T) which carries the water to be treated. The transformer portion also includes four coils (P1, P2, S1, S2), wherein the two primary windings (P1, P2) are wound in opposite directions to one another and are connected to subtract their potential differential and the two secondary windings (S1, S2) are wound in the same manner but in opposition to the phase of the primary windings. In this way, enhanced tuning with the resonator portion of the decalcifier is achieved. The decalcifier successfully maintains minerals in solution for water undergoing a heat cycle and also inhibits the growth of algae and bacteria in water.
