Closed-loop cooling tower(Also known as an evaporative air cooler or closed-loop cooling tower, or abbreviated as "closed tower") Originating from the evaporative cooler, it is characterized by the closed-loop circulation of the cooled fluid between the heat exchanger walls and the external process equipment, distinguishing it from the general cooling tower where the cooled fluid directly contacts the air. Hence, it is referred to as the "closed tower," while the general cooling tower is correspondingly called the "open tower."

Features: Closed-loop cooling tower system for safe and reliable operation; significant water-saving effect; excellent cooling performance; low operation costs; and effectively addresses the issue of corrosion and scaling on the cooling walls due to cooling water.

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, water-cooled machine room air conditioners, etc.).
