ELECTRONIC ANTI-SCALING Building and industrial plant protection (up to 100 m3/h) OPERATING PRINCIPLE Electronic anti-scaling systems (patented process) apply an AC pulse electrical field to the natural electrical charges of the calcium ions (Ca2+) and hydrogen carbonate ions (H2CO3-)that are dissolved in the water. The action of this electrical field causes ionic movement (Coulomb’s law). This movement displaces the calcium-carbon balance towards the formation of nano-crystals of calcium carbonate (CaCO3). 2 HCO3– + Ca2+ ⇔ CaCO3 + H2O + CO2. These nano-crystals remain in suspension in the water flow and stimulate crystallisation by fixing calcium ions that haven’t been transformed. Scaling is thus neutralised without the calcium having been removed from the water. The nano-crystals are evacuated as water is drawn off for consumption. Calcium is perfectly assimilated by the human organism. F IELDS OF APPLICATION - General cold water supply in buildings. - Community buildings (cold water, sanitary hot water). - Retirement homes. - Heat exchangers. - Cooling circuits. - Foodstuffs, industrial and pharmaceutical processes with no water evaporation phase. - Water pumping and treatment stations. MAJOR ADVANTAGES of electronic anti-scaling - ressurised installations effectively protected against scaling. P - Progressive descaling of old installations. - Physical process leaving all minerals and trace elements in the water. - Preservation of water drinkability and of its calcium carbon balance. - eaves a light whitish powdery non-binding film (calcium) when the L water evaporates in the open air, but which can be wiped off without abrasion or solvent. - Does not consume water or salt. Electricity consumption is low. - No maintenance required. - Average life cycle: 20 years. - Process manufactured since 1987.
