Four stage water treatment system to remove limescale, Legionella bacteria, dust and other contaminants. Firstly, water is filtered to reduce dirt and other contaminants. Secondly, the structure of the lime molecules is altered, thus preventing sediment of limescale to occur on the surfaces of the air cooling equipment components. The structure of the molecule of the lime is altered with the help of special electro-magnetic magnet and BIO tablets, which simultaneously protect metal parts from rust. Thirdly, water is radiated with UV rays to prevent Legionella and other bacteria formation in the water.
