Product Description

NWN-S series Full- Stainless Steel Closed Type Cooling Tower/ Closed Circuit Coolers

NWN-S series Full- Stainless Steel Closed Type Cooling Tower is type of NWN series counter flow closed cooling tower combined with multiple units is available, closed loop, clean medium, not easy to scale, energy saving and water saving, support dry operation mode without spray water in winter, can replace chillers in winter, greatly reduce energy consumption. Imported material shell, suitable for various severe environments, the self-draining liquid heat exchange coil is shut down, which is convenient for anti-freezing protection in winter.


Frame structure

Stainless steel heavy duty construction, strong corrosion resistance and long lifetime.
 

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.
