Product Description

Industrial Counter Flow Closed Circuit Cooling Tower 


NWN series counter flow closed type cooling tower, also called Induced Draft Evaporative Closed Circuit Coolers, Closed loop system design, Trouble-free process operation-closed loop protection of process fluids and equipment from external contamination, Widely used in data centres, battery plants, grow room facilities, high-efficiency chiller applications and multiply different types of industrial process. 



Feature
Large internal space & smaller occupied area.
Excellent heat exchange performance & smaller wind resistant.
Non-stop maintenance & simple maintenance work.
Closed circuit design ensures high water quality .


Frame structure

Modular structure, use the high quality of zinc magnesium aluminum material (304 or 316 stainless steel for option), which is standardization made by Z700 galvanized anti-corrosion processing.After passivation treatment, cooling tower can withstand water PH value 6.5-9.0 . At the same time, the component design strength can bear the wind pressure of 1440 Pa, Protected the product quality and ensured stable running.

Stainless steel Cooling Coil
& Easy disassembled type inlet grille

- Stainless steel Cooling Coil, longer equipment life, higher thermal efficiency, higher corrosion resistance, lighter, recyclable. 

- Process fluid is circulated through 304 stainless steel coil in closed loop system, reduced water treatment chemicals, reduced water consumption. 

- Easy disassembled type inlet grille, special 3D stereo 45-degree ventilation channel, greatly improves product and wind load resistance.
Reduce noise and prevent the growth of algea. Anti-corrosion, anti-ultraviolet, maintenance-free.

High efficient fan drive system
& PVC drift eliminator

- High efficient fan drive system, Small wind resistance, big air volume, low noise, good performance, high efficiency. Streamline high strength fan stack gurantees airflow uniform through the fan inlet and outlet area, maximum reduce the energy comsuption. Fan motor's protection class: IP55, Insulation class: F class.

- NEWIN EVD series drift eliminator , using advanced self-extinguishing PVC materials with high thermal performance. Capture large water droplets caught  in the cooling tower air stream,improving high thermal transfer performance.
