VELOCITY RECOVERY FAN STACK / FAN CYLINDERS

FAN CYLINDER
A SMALL 5.5 MTR DIA FAN CYLINDER, OF HEIGHT 1.8 MTR ONLY

Also called as Fan Stacks, we offer Fan Cylinders for Fan Diameter starting from 1.8 Mtr to 12 Mtr. These are typically made in Segments, with multiple Segments being bolted together to form the require circumference suitable for required Fan Size. Like Diameter the Height is also variable  with the smallest being 600 MM and Tallest being 5500 mm. Following may be observed as some of the main objectives of using proper fan cylinder,

  1. Collecting and channeling the air at the Fan level,
  2. Pushing the Air into right direction, away from the Cooling tower, to minimize recirculation,
  3. Velocity recovery designs actually do the work of fan, and reduce the load on the Fan, by pulling the air from top of the Fan,
  4. These also provide safety to maintenance staff, from the high speed & powerful fan blades.
 

Access to Gearbox / Fan in Bigger Fan Cylinders is via Removable Segments. In still bigger Sizes Windows or Box Doors are  provided for easy of entry inside. However, in these cases the Gear Boxes  / Fans need to be Lifted from the Top via Crane or Pulley only.

As the Size Increases, Fan Cylinders start getting affected by Strong Winds / or Lack of proper foundation. Although Winds cannot be controlled, better stronger designs prevent these huge structures from breaking in Storms. The smallest weighs only 20 Kgs, whereas the biggest one made by us weighs nearly 2,500 Kgs.
