Corrosion inhibitor closed cooling systems Molybdate Phosphonate

Molybdate and phosphonate based corrosion inhibitor for cooling water system. We are manufacturer and supplier of this special type of corrosion inhibitor which acts as Filming Agent to protect metal surface from corrosion and its chemical reaction also help to prevent formation of calcium phosphate deposition.

The synergistic blend provides outstanding multi-metal protection, preventing corrosion on mild steel, copper, brass, and other system alloys. It offers anodic protection, while stabilizing the formulation and controls scale formation. The product ensures long-term system reliability, reduced downtime, and extended equipment life. Designed for industrial and HVAC closed loop applications, it performs effectively at low treatment concentrations.

Application

RXSOL-40-4018 is mainly applied in secondary cooling water systems of Power Plants, in the cooling systems of blast furnaces, in systems for cooling the molds in continuous casting mills and in hot and cold water systems in the chemical industry. The program should be used with soft water, to avoid calcium phosphate deposition when the water losses are important.

 

Ingredient: Metal Pretreatment Filming Agent, Film Settlement Agent, Surface Activating Agent, Sodium Molybdate, Organophosphorus etc.                                                                               

Corrosion Rate             : ≤0.125mm / year (Steel)                                                   
Scale Formation Rate  : ≤0.2mm / year

Dosage

RXSOL-40-4018 is added neat or diluted to the cooling water. RXSOL-40-4018 can be mixed with water in any ratio.

Dosage requirements - The dosage rate is dependent on the system conditions and the amount of water lost from the system.

Systems should maintain 400 ppm - 1000ppm of product in the water, while systems with high water losses should maintain ca. 1500 ppm in the system.

For further technical assistance please contact RX MARINE TECH DEPT.

DOSAGE: Corrosion inhibitor closed cooling systems Molybdate Phosphonate dosages may vary somewhat according to operating conditions, but generally 400-1000 ppm of Corrosion inhibitor closed cooling systems Molybdate Phosphonate should be maintained in the system water. This dosage should be doubled for a two-week period when initiating treatment, whenever the system is refilled with fresh water, and after any major system upsets, in order to establish effective corrosion control. If the stability index of the recirculated water is higher than 10.5, an alkalinity booster such as RXSOL pH Booster should be fed to reduce the index to less than 10.5.

Corrosion inhibitor closed cooling systems Molybdate Phosphonate should not be used when the stability index of the system water is below 3.0.

Corrosion inhibitor closed cooling systems Molybdate Phosphonate is controlled by a molybdate test, which provides easy and accurate control readings. Maintain 1 to 5 ppm MoO4 = at all times.

FEEDING: Corrosion inhibitor closed cooling systems Molybdate Phosphonate must be fed continuously to the system by a positive displacement chemical feeder. For maximum results, feed should be linked to makeup of bleedoff through the use of a flowmeter or conductivity controller. Residuals are adjusted and maintained by chemical test of the system to provide a residual of 1-5 ppm MoO4 = .

HANDLING: Avoid contact with skin and eyes. Wear suitable protective equipment (refer to MSDS for further information).
