Chiller Descaling: Choosing the Right Chemical Solutions
Essential guide on safely descaling industrial chillers. Learn how to choose inhibited sulfamic acid and why neutralizing washes are mandatory for copper coil protection.
Maintaining Heat Exchanger Integrity
When descaling industrial chiller tubes, using the wrong acid can be worse than no cleaning at all. Improperly inhibited acids will aggressively etch the copper tube wall, thinning it until the pipe bursts.
Choosing the Right Descalant
- Inhibited Sulfamic Acid: The industry standard for copper coils. It dissolves calcium carbonate effectively but contains specific inhibitors to protect copper and brass.
- Neutralization Wash: Always follow the acid cycle with a high-pH neutralizing rinse. Leaving acidic residue causes "flash-rusting" on the copper surfaces.
