Cooling water inhibitors are chemicals added to cooling systems to prevent corrosion, scaling, and microbial growth. They protect metal surfaces and maintain system efficiency by forming protective layers or neutralizing harmful reactions. Common inhibitors include phosphates, silicates, and biocides tailored for specific water conditions.

Key specifications and technical properties of Cooling Water Inhibitors and Cooling Systems include:

Size: Varies based on system capacity, typically ranging from small (1-10 gallons) to large (100+ gallons).

Grade: Industrial, commercial, or automotive grades available, depending on application.

Viscosity: Typically low to medium (1-100 cP) for inhibitors to ensure proper flow and mixing.

Buoyancy: Not applicable for inhibitors; cooling systems may use buoyant materials for float valves or sensors.

Material: Inhibitors often contain phosphates, silicates, or organic polymers; cooling systems use metals (copper, steel) or plastics (PVC, polypropylene).

pH Range: Inhibitors usually maintain pH between 7.5-10 to prevent corrosion.

Concentration: Inhibitor dosage typically 50-500 ppm in cooling water.

Operating Temperature: Systems typically handle -20°C to 120°C, depending on design.

Pressure Rating: Cooling systems may range from 10-150 psi, based on application.

Corrosion Protection: Inhibitors provide <0.5 mpy (mils per year) corrosion rate for metals.
