Mitigating Scaling & Fouling in Centrifugal Water Chillers
Engr. Fahim Chowdhury•August 11, 2026•5 min read
Preventative thermal performance management and chemical dosing protocols for large commercial cooling towers.
1. Condenser Water Treatment Principles
Scaling on condenser tubes significantly degrades heat transfer coefficients, leading to high head pressure trips and increased specific power consumption (kW/ton).
2. Automated Tube Cleaning Systems (ATCS)
Periodic sponge-rubber ball circulation through condenser bundles cleans internal tube walls on-line without interrupting continuous refrigeration cycles.
