 Features 
 

▶ High quality galvanized sheet, strong corrosion resistance and long lifetime 

Z7 galvanized high corrision resistance plate, with strong thermal resistance, high heat resistance, beautiful appearance, ect. The structure plates are fastened with 304 stainless steel bolts.




▶ Stable Axial flow Fan motor system, high efficiency & energy saving

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.



► Strong corrosion resistance 304 Stainless Steel Coil isolates the process fluid.

Process fluid is circulated through 304 stainless steel coil in closed loop system, reduced water treatment chemicals, reduced water consum ption and reduced maintenance.





►NEWIN EVD series drift eliminator efficiently remove the exhaust air flow entrained water droplets

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.



 
►NEWIN EVL 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.
