Corrosion inhibitor for copper/copper alloy system
Corrosion inhibitor for copper/copper alloy system
Application & Uses
Use RXSOL Corrosion inhibitor for copper/copper alloy system anywhere where the system is made of copper, brass, bronze, etc
- Closed loop cooling water systems
- Open recirculating cooling towers
- Chilled water circuits
- Heat exchangers and condensers
- Copper tube heat exchangers
- HVAC systems
- Marine cooling systems
- Industrial process water systems
- Copper, brass and bronze piping systems
Dosage & Directions for Use
For systems which don’t contain aluminium RXSOL Copper Corrosion Inhibitor should be added to the system at an initial dosage rate of 5 – 10 litres / 1000 litres of system water content (increase to 10 – 15 litres / 1000 litres for systems containing aluminium). This will passivate metal and should establish the required minimum Molybdate reserve of >33mg/l. Whenever the system is drained or loses a significant quantity of water then the additional RXSOL Copper Corrosion Inhibitor should be added at the rate of 5 – 10 litres / 1000 litres of water added (increase to 10 – 15 litres / 1000 litres for systems containing aluminium).
For systems containing aluminium it is important to maintain the system water pH in the range 7.0 – 8.0. Occasionally depending on the water characteristics and system treatment history the pH may rise above pH 8.0 which means that the risk of aluminium corrosion is increased – if this happens then high pH can be reduced by adding an appropriate quantity of pH Conditioner.

Product Description & Chemical Profile
RXSOL-40-4017 is an excellent organic, film forming, liquid corrosion inhibitor product developed specifically for copper and copper alloy based water systems. RXSOL-40-4017 is designed to supplement other chemical treatments used in open re-circulating cooling water systems that contain copper or copper alloys.
In general, 0.5 - 2 ppm of active benzotriazole is needed for system control. This is about 1.5 - 6.0 ppm of RXSOL-40-4017.
Corrosion Inhibitor for Copper or YELLOW systems - copper, bronze, brass, etc - a premium liquid corrosion inhibitor specially developed for the protection of copper and copper-alloy metallurgy including copper, brass and bronze used in recirculating cooling water systems, heat exchangers, condensers, chilled water circuits and industrial water systems.
The product forms a highly adherent and invisible molecular protective layer on metal surfaces that minimizes electrochemical corrosion reactions while maintaining excellent heat transfer efficiency. It effectively protects yellow metals against oxidation, dezincification, pitting and galvanic attack under a wide range of operating conditions.
RXSOL Copper Corrosion Inhibitor is compatible with most common water treatment programs and can be used alone or in conjunction with scale inhibitors, dispersants and microbiological control programs.
