They facilitate the removal of heat by circulating water through a heat exchanger, passing it through fill media where it is cooled by air.
Frequently, closed circuit cooling towers are used in industrial settings to protect sensitive equipment from process contamination, with water passing through coils while air and a secondary spray water stream provide cooling.
Key elements include high thermal efficiency, anti-clogging performance, and resistance to corrosion from circulating water, often managed with corrosion inhibitors like sodium benzoate and zinc sulfate.
Common components include industrial-strength spray pumps, fan motors, and fill media designed to maximize heat rejection.

Choosing our equipment means choosing a strong and professional technical team, first-class quality and perfect after-sales guarantee.
Closed Type Cooling Towers are specifically designed for cooling CCR casting machines, plate heat exchangers, and rolling mill speed reducers to ensure continuous and stable production.
The closed-loop design prevents process water contamination by circulating it through sealed 304 stainless steel coils. External air and secondary spray water provide the necessary cooling without exposing the primary loop to the environment.
These cooling towers are constructed using SS304 (304 Stainless Steel), which provides exceptional corrosion resistance and durability in demanding industrial environments.
We offer configurations ranging from 50-ton, 100-ton, 150-ton, 200-ton, up to 300-ton capacities to meet different flow rate and power requirements.
Yes, we provide a professional technical team to visit customer sites for installation, commissioning, and face-to-face technical guidance.
