Corrosion inhibitors for Closed, heating and cooling water systems
Corrosion inhibitors are an essential to ensure the longevity and efficient operation of your closed heating or cooling water system. The two main types of treatment for closed systems are nitrate or molybdate based corrosion inhibitors. In certain circumstances using a Tannin based inhibitor may be a better choice if, for example, the system is high pressure, predominantly steel or of significant size. In these circumstances,Tannin can provide a more cost effective solution.
Synergised or Traditional Inhibitor
A traditional nitrite treatment is common in many systems and still considered effective. However, it requires a higher dosage rate than modern synergised blends. A synergised nitrite treatment comes with a blend of organic corrosion inhibitors intended to protect steel, copper and other non-ferrous metals (excluding aluminium). The synergised blend much more cost effective, as the nitrite reserve required to offer the system a high level of protection is much lower
