NSN Series Counter Flow Fill S Wave Shape Excellent Cooling Efficiency And Good Performance In Processing Dirty Water
"S" wave counter flow type cooling tower fills are the most widely used cooling tower fills. Due to its big space design, and S wave shape, The fills have excellent cooling efficiency and good performance in processing the dirty water, especially the processing water contains solid impurities.
The "S" wave cooling tower infills made by PVC/PP material, thermal forming by mold and plastic forming machine. Sheet thickness and color can be customized. All these advantages makes its become the ideal infill for counter flow industrial cooling tower, Power plant heave duty cooling tower, NH3 plant cooling tower, sewage treatment cooling tower and so on.
