Corrosion Inhibitors vs. Scaling Inhibitors – Do You Need Both in GCC Cooling Towers?
Keywords: corrosion vs scaling inhibitors, scale and corrosion control GCC, cooling water chemicals UAE, inhibitor for cooling tower Oman
Introduction
Facility managers in the GCC often confuse corrosion inhibitors with scale inhibitors. But these are two separate issues — and each requires a unique treatment approach.
Corrosion vs. Scale: What’s the Difference?
| Parameter | Corrosion | Scaling |
|---|---|---|
| Cause | Chemical reactions with oxygen and acids | Precipitation of calcium, magnesium salts |
| Symptoms | Rust, pitting, metal thinning | White deposits, reduced flow |
| Solution | Use of corrosion inhibitors | Use of antiscalants or scale inhibitors |
Why Both Are Needed in the GCC
- Hard water areas like Riyadh and Sohar are prone to scaling.
- High ambient temperatures and saline air promote corrosion.
- Chillers, cooling towers, and HVAC systems are exposed to both risks simultaneously.
Conclusion
Don’t make the mistake of choosing one over the other. Invest in a dual-inhibitor program that includes both corrosion and scale inhibitors for maximum cooling system protection.
