In this type, the tube bundle is located on the discharge side of the fan.  Virtually one can see the fan is located below the tube bundle.


  • Easy access to maintenance for fans and bundles
  • Accommodates higher process inlet temperatures
  • Possibly less power requirement if effluent air is very hot
  • Fans remain in cold ambient temperatures


  • Increase possibility of recirculating of hot effluent air resulting from low discharge velocity from the bundles, high velocity in inlet fan rings, and no stack.
  • Less uniform velocity across tube bundles
  • Completely exposed tube bundles to sun, rain and dirt resulting in poor process control and stability

Low natural draft capability on fan failure
