dvr Scale and Corrosion Inhibitor for Cooling Water

Metallic corrosion and scale controlling advanced formulated product for open and closed cooling systems. A blend of phosphonate, and polymers incorporating dispersants. It is designed for the prevention of hardness deposition in recirculating or once through cooling systems using moderate to high hardness make-up water . Rxsol Scale and Corrosion Inhibitor  is scientifically formulated from a combination of polymers to offer excellent calcium  along with general scale inhibition in cooling water systems, even under extreme system conditions. Rxsol Scale and Corrosion Inhibitor  is made up of halogen stable polymers that do not form insoluble calcium salts when added to hard waters.
