China Closed Cooling Tower

China-made closed circuit cooling towers

Here’s a quick breakdown :

What is a Closed Circuit Cooling Tower (China context)?

Closed circuit= water (or process fluid) circulates inside a coil heat exchanger, and external spray water + airflow remove heat.

Advantage: Prevents process water contamination, reduces scaling, and minimizes water loss compared to open towers.

Popular in HVAC, chemical plants, data centers, and industrial cooling in China.
