CHEMZOL 9330
Scale and Corrosion Inhibitor for closed loop systems without presence of any heavy metals
CHEMZOL 9330 Corrosion Scale Inhibitor Cooling Water Treatment is a powerful corrosion and scale inhibitor specially formulated for closed-loop hot and cold water systems. This advanced phosphonate-based blend is nitrite-free, heavy metal-free, and environmentally responsible. CHEMZOL 9330 protects metallic components from corrosion while preventing scale buildup, thus enhancing system lifespan and energy efficiency.
CHEMZOL 9330 Corrosion Scale Inhibitor is essentially non-toxic, does not contain zinc, chromate, or other environmentally harmful heavy metals, and is ideal for industrial water treatment applications where safety, performance, and sustainability are priorities.
Key areas of use
- Closed-loop chilled water systems
- Hot water heating loops
- Industrial cooling systems
- HVAC & refrigeration circuits
- Geothermal and solar thermal loops
