Product Description: Closed-loop cooling towers (also known as evaporative air coolers, closed-type cooling towers, or simply "closed towers") originate from evaporative coolers. Due to the closed-loop circulation of the cooled fluid between the wall-type heat exchanger and the external process equipment, they are distinguished from the general cooling towers where the cooled fluid comes into direct contact with air. Hence, they are referred to as "closed towers," while the general cooling towers are correspondingly called "open towers."

Features: System with closed cooling towers ensures safe and reliable operation; significant water-saving effect; excellent cooling performance; lower operating costs; and effectively addresses the corrosion and scaling issues of cooling water on cooling walls.

Application Sites: Widely used in power generation, metallurgy, chemical industry, HVAC fields; as well as in harsh operating environments; also applied in refrigeration and air conditioning systems requiring precise control (such as water source heat pumps, dedicated air conditioning for water-cooled machine rooms, etc.).
