  • Which chemistry is used in closed cooling water systems?
  • In open cooling water systems, typical chemistry is designed to inhibit both. But, in closed cooling water systems, anodic inhibition is the typical method. Sodium di-chromate (Na 2 Cr 2 O 7) formerly was the most common chemical feed to both open and closed cooling systems.
  • Should closed water systems be treated?
  • With proper maintenance and annual water losses under 10% of the initial volume, ongoing chemical water treatment costs are low. Given the potential risks and the benefits of treatment, the choice is clear—all closed systems should be treated to achieve the lowest possible corrosion rates.
  • Why do closed circuit systems need water treatment?
  • Without effective water treatment corrosion products and fouling can build up in closed circuits impairing flow and heat transfer. To ensure that closed circuit systems are well maintained and can overcome these problems Radiant has a wide range of products for chilled water systems, water cooled compressors and hot water systems.
  • What is the best corrosion inhibitor for closed cooling water systems?
  • The three most reliable corrosion inhibitors for closed cooling water systems are chromate, molybdate, and nitrite materials. Generally, the chromate or molybdate types have proven to be superior treatments. For mixed metallurgy systems, the molybdate inhibitors provide the best corrosion protection.
