NWF series mixed flow evaporative fluid coolers, this
mixed flow closed circuit cooling tower is a type of closed cooling tower designed with pvc fill packing heat exchange layer and high corrosion resistant stainless steel cooling coil. Efficient cooling, Low consumption and Energy saving.
NWF series closed cooling tower 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.
Optional Accessories
Noise reduction upgrade / Anti-Freeze heater / Vibration isolator / Stainless steel casing and framework / bolts and nuts (304 / 316)
High-temperature upgrade / Dual-speed Motor & VFD motorAnti-Freeze heater
Application
- HVAC system - Pharmaceutical industry - Metal processing
