The fan cylinder does far more than protect operating personnel from a rotating fan. It is a vital link in the chain of critical components that contribute to the overall ef¬ficiency of the cooling tower. When correctly designed, manufactured and applied, it assures that the fan will be capable of moving the maximum amount of air through the tower at the minimum required horsepower. Poorly designed or uti¬lized, it contributes virtually nothing to the fan's capability and, in some cases, can be more of a hindrance than a help.
For a optimum fan performance the fan stack must have dimensional stability for a perfect fan-tip stack clearance, proper smooth air intake and at the exhaust side a flare of 7~8 deg The fan stacks we manufacture are of 8 degree flare diffuser type with elliptical or parabolic air inlet..
The air enters the elliptical fan-inlet with minimum turbulence and wake at the fan, optimizing the fans performance as the airflows out of the stack it recover static pressure, and reduces power cost.
Our FS are designed manufactured on this basis we have an in house facility to make the pattern, mould, in a short time and manufacture.
Fans stack are taken up for manufacturing after approval of the drawings by the client, we use best materials unsaturated polyester and fiber CSM from reputed manufacturer and use hand layup process. The Fans stack thickness, dimensional stability and weight per segment is maintained throughout the manufacturing process.
