Specialized formulation designed for complete chemical treatment of boiler water supplied with low alkalinity water. It neutralizes the oxygen naturally present in the water and forms a layer of magnetite on the metal to avoid surface corrosion; prevents the formation of encrustations, acts on suspended solids, keeping them in a state of fine dispersion and corrects the pH value within the limits recommended by current regulations; reacts with carbon dioxide present in the water, adjusting the pH value and protects all metal surfaces in contact with steam or water from corrosive phenomena, due to the aggressiveness of carbonic acid.
