S Corrugation Cooling Tower Fills
The efficiency of a cooling tower depends upon its fill, the fill is made of rigid PVC or PP film of flame retardant quality with high heat exchange efficiency.
The high efficiency fill reduces the motor input HP and assures uniform distribution of water, with minimum resistance to air flow.
Below roll fillings is applied to Newin brand counter flow round type & square type cooling towers, block/sheet fillings is applied to cross flow square type cooling towers.
NSN Counter Flow Cooling Tower Fills
"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 it 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.
