Then Raprezol is included in the 220V network, and it starts to work. The principle of operation of the apparatus is the emission for water of electromagnetic waves. Waves are served with a certain amplitude and frequency, this converts the structure of the scale, consisting of 98 % of magnesium and calcium carbonate. Those cease to turn into crystals, but begin to spin and they are carried away by a stream of water. The surface of the protected equipment remains clean. The water in the chemical composition does not change at all.
