Mixed flow closed type cooling tower

NWF
NWF Series Mixed Flow Closed Type Cooling Tower

Normal Model: NWF-120/180...1750-Z7-S
Cooling Tower Type: Mixed flow closed type
Cooling Mode: Wet cooling mode
Heat exchanger: Stainless steel heat exchange coil
Air Ventilation: Aluminum alloy axial fan drive system
Cooling Tower Body: Z700 HDGS (SUS304/316 or Armour anti-corrosion coating plate for option)




NWF series mixed flow closed cooling tower is to flow the fluid medium that needs to be cooled in the high-efficiency serpentine heat exchanger, and the external spray system continuously wets the surface of the coil for cooling, so that the cooled medium passes through the partition wall heat exchange. The device exchanges heat with the spray water. The water sprayed on the coils flows through a section of PVC heat exchange layer with efficient cooling effect to be cooled and then falls into the water collection basin for recycling.

NWF series adopts composite flow cooling technology. Air is simultaneously sucked in and passed through the coil and the PVC heat exchange layer. Through evaporation and heat transfer, the heat is taken away from the spray water, cooling the coil and the fluid medium in the coil.

Equipment can be ordered according to single cell or multi cells.  

Main Parts

▷ Stainless Steel Heat Exchange Coil
Longer equipment life, Higher thermal efficiency, higher corrosion resistance, lighter and recyclable.
Copper, 304/316 stainless steel or titanium alloy material coils for option.




▷ High quality PVC fill packing heat exchange layer
Brand new self-extinguishing PVC fills, the inlet grill and the water collector are integrally formed. 
It can be upgraded to high-temperature materials according to the working conditions of the project. 



▷ High efficient fan drive system
Closed cooling tower series adopts big brand axial flow fan with the features: Stable & High efficiency, Low noise & Strong corrosion resistant.
Two- speed or variable frequency, and anti- explosion motor for option.
