Glycol Antifreeze Inhibitor WM8703 For Use In Glycol/Water Systems

Description:

Glycol Antifreeze Inhibitor WM8703 is a concentrated liquid formulation designed specifically for use in Glycol/Water systems.

Glycol Antifreeze Inhibitor WM8703 is a non-toxic environmentally friendly material suitable for use in both Ethylene and Propylene Glycol systems. Glycol Antifreeze Inhibitor WM8703 provides protection for both ferrous and yellow metals and unlike traditional Molybdate and Nitrite inhibitors does not contribute to toxicity. Glycol Antifreeze Inhibitor WM8703 teclmology is also designed to prolong the service life of the Glycol by minimizing the potential for acid degradation. Glycol Antifreeze Inhibitor WM8703 is formulated to provide a large excess of buffering capacity as well as inhibit corrosion.

The inhibitor used in glycol/water systems is Dipotassium Phosphate. The Phosphate based inhibitor is effective in preventing corrosion of metal commonly used in HVAC, food processing and process heat transfer equipment. These inhibitors prevent corrosion of metals in two ways:

First they passivate the surface of the metal, reacting to the surface to prevent acids formed as a result of glycol oxidation. All glycols produce organic acid as degradation products. The degradation is accelerated in the presence of oxygen and/or heat. Left in solution, such acids lower the pH and contribute to corrosion. Hood Chemical's inhibitor package neutralizes these acids.

The primary control is the maintenance of an adequate level of "Reserve Alkalinity" in the system glycol fluids. Normally, a Reserve Alkalinity of at least 8 mls is recommended and can easily be tested with Hood Chemical's "ALKLANITY COMPARITIVE TEST KIT".

The use of sodium nitrite or sodium molybdate as the primary inhibitor in glycol systems, risk sacrificing the longevity of the glycol and the possibility of system damage and downtime for repairs or replacement due to the limited buffering capacity.
