description and use
CorrShield MD4100 is a blend of inhibitors designed to control corrosion, scale and deposition in closed cooling systems. CorrShield MD4100 contains molybdate and nitrite, which provides rapid passivation and lasting protection of mild steel against corrosion.
typical applications
CorrShield MD4100 provides a complete corrosion inhibitor, scale inhibition and dispersant programme for mixed metallurgy closed cooling systems. The product may be applied to closed cooling systems that use demineralised, reverse osmosis permeate, ion exchange softened or hard water, as make up water. CorrShield MD4100 is also designed to inhibit corrosion of copper metallurgies and to control fouling caused by particulate matter and inorganic scales, such as calcium carbonate.
treatment and feeding requirements
Proper treatment levels of CorrShield MD4100 depend on many factors, such as corrosion and scale potential, and conditions particular to a given installation. The product should be used in accordance with control procedures that VEOLIA establishes for a specific application.
The product may be fed directly from the shipping container or storage tank to a point in the system where it will be rapidly mixed with the bulk cooling water.
Equipment recommendations for specific blends are available upon request.
The product may be fed continuously based on the make up water rate, or intermittently based on residual required and the system water volume. Feed of CorrShield MD4100 is controlled by a simple and accurate molybdate test.
