RXSOL-40-4026-025 is a superior corrosion inhibitor developed for use in closed water circulating systems containing aluminium. RXSOL-40-4026-025 is based on a novel blend of organic and inorganic corrosion inhibitors, including molybdate, intended to protect steel, copper and other nonferrous metals. RXSOL-40-4026 is an ideal treatment for closed chilled water and low pressure heating systems. Whilst RXSOL-40-4026 is designed to protect systems which incorporate aluminium, it should NOT be used in systems with “Stelrad Super Plus Modular” boilers where an alternative product should be used. In all applications of RXSOL-40-4026, where aluminium is present it is important to control the pH in the range 7-8.
