COOL-C18 is a nitrite-based corrosion and scale inhibitor designed for industrial closed cooling and engine cooling systems. This superconcentrate product is suitable for various stationary and mobile equipment, including General Electric (GE) locomotives and engines. When properly diluted with water, COOL-C18 helps dissipate heat, prevent corrosion, and stop scale and deposit buildup in cooling system passages. It must be diluted before use, with an initial treatment rate of 4%, using demineralized or deionized water. COOL-C18 is ideal for a wide range of cooling and heat transfer systems in industrial applications.
