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.

Features 

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

Stainless steel 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, Explosion-proof motor configuration, high efficiency & energy saving

Small wind resistance, big air volume, low noise, good performance, high efficiency. Streamline high strength fan stack guarantees airflow uniform through the fan inlet and outlet area, maximum reduce the energy consumption. Explosion-proof 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 consumption 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 series 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.
