DESCRIPTION AND USE

NT4209 is an alkaline, nitrite-based corrosion inhibitor which is designed for use in the treatment of closed water systems. Corrosion control is achieved by establishing a passive inhibitor film on the metal surfaces. This film contains nitrite and organic corrosion inhibitors.

TREATMENT AND FEEDING REQUIREMENTS

Typically the closed cooling water should be maintained at a high pH with this inhibitor. Proper treatment levels for NT4209 depend on several factors such as the corrosion potential and conditions particular to a given installation. The product should be used in accordance with control procedures that Demih Industry establishes for a specific application.
