The Complete Guide to Closed-Loop Cooling System Water Treatment with Shanghai ChiMay Closed-loop cooling systems are sealed from the atmosphere, but that doesn’t make them immune to water quality problems. Corrosion, microbiological growth and chemical degradation all happen inside the loop—silently. Maintained properly, a closed-loop system can run 20+ years without major water-side failures, but…
The 2026 Engineer’s Handbook to Cooling Tower Water Optimization by Shanghai ChiMay The numbers tell the story: facilities running comprehensive sensor-based optimization programs report water savings of 20–40%, energy improvements of 5–12% and chemical cost reductions of 25–35%. Cooling tower water optimization has moved from a chemical-focused discipline to a data-driven engineering practice—real-time sensor networks,…
When engineers discuss cooling tower optimization, attention typically focuses on the recirculating water itself—its temperature, its chemistry, its biological load. But the quality of water entering the system, known as make-up water, is equally important. Make-up water is the largest external input to the chemistry of an open recirculating loop: every liter of water lost…
AOP retrofits are picking up steam in industrial cooling, driven by water scarcity, chemical cost pressure and tighter discharge rules. The Cooling Technology Institute has described AOP-based treatment as a way to keep cooling tower water cleaner and more stable, with fewer operational variables. But an AOP retrofit is not a drop-in swap. It changes…
How Top-Performing Facilities Achieve Near-Zero Blowdown in Cooling Towers: A Shanghai ChiMay Analysis Blowdown eats 25–40% of total make-up water consumption in conventional cooling tower operations—the single largest controllable water loss in an open recirculating system. Yet a growing number of facilities worldwide have cut blowdown by 80–95% from baseline, and some are effectively at…
