Corrosion Inhibitors Cooling Systems ChemTreat, Inc.

ChemTreat’s all organic corrosion inhibitors for open recirculating cooling water systems generally contain an organic phosphate and may also contain polymeric dispersants, polyacrylate, and/or polymaleic anhydrides, copolymers, and a copper inhibitor. Sodium molybdate may also be included in these treatment programs for testing and control.

TREATMENT AND CORROSION CONTROL OF COOLING

Corrosion inhibitors may be used in cooling systems to modify the electro chemical process and control the corrosion. Natural scale formation due to hardness salts may also affect the electro chemical process and provide a degree of corrosion control (see Appendix 3).

MOLYBDATES – Corrosion Inhibitor – Bio Source Inc

In water treatment, sodium molybdate (Na 2 MoO 4) has proven to be a superior corrosion inhibitor in open recirculating cooling systems and closed recirculating cooling systems. It is often applied at lower levels and in combination with other inhibitors, such as inorganic and organic phosphates.

Cooling towers are vulnerable to a variety of contaminants that cause deposit formation, such as mineral scales and sludge. Deposition interferes with heat transfer, increases corrosion rates, restricts water flow, and causes loss of process efficiency and production.To ensure such cooling systems are accurately maintained and operate at optimum efficiency it is essential that the correct

Molybdate and Non Molybdate Options for Closed

Closed recirculating systems or closed hydronic loops utilize a water based solution to transfer heat. The most common distinction defining a closed system is the fact that the method of cooling is non evaporative. Minimal water loss/makeup requirement and minimal air contact are two additional conditions typically associated with closed loops
