Closed Cooling Tower
The RNNS series intelligent double cycleClosed Cooling Tower applies composite flow cooling. Its shell can adopt 304 stainless steel or anti-corrosion galvanized plate, and stainless steel or copper tubes are optional.
Equipped with a high-efficiency dehydrator for ultra-low water drift loss, it features closed circulation of cooling medium to prevent impurity ingress and maintain medium purity; soft water or antifreeze is used in internal circulation to avoid scaling and pipeline blockage.
This cooling tower occupies a small area and supports flexible relocation, with low maintenance costs for long-term operation.

Advantages
No scaling in closed internal circulation The internal circulation adopts soft water or antifreeze to prevent scaling. It cuts maintenance costs, keeps the compressor inlet temperature low, extends the service life of wearing parts and reduces compressor energy consumption.
Intelligent control for energy saving The cooling tower supports frequency conversion or multi-stage control according to working environment and operation time, to realize optimal matching between equipment and surroundings and lower energy consumption.
Simple maintenance and long service life Key system components adopt high-quality materials, main accessories are supplied by well-known brands, and the main structure is reinforced at the design stage.
Open & closed complementary design with wide applicability It combines merits of open square counter-flow cooling towers and fully air-cooled closed cooling towers, meeting diverse application requirements.
High heat exchange efficiency & low water drift and noise It delivers excellent heat transfer performance while featuring ultra-low water drift rate and low operating noise.
Stable closed circulation system The closed internal circulation protects cooling medium purity, avoiding impurity contamination and bringing reliable operation.
