Twin-Blade Louver Damper

Function:

  • 100 % isolation with seal air, providing "man-safe" sealing

 

Application:

  • Twin-blade louver dampers have been developed for the demanding conditions in FGD plants as a superior alternative to double louver dampers
  • Process industries, gas turbines, coal fired and environmental applications

 

Advantages:

  • Reduced flange to flange size
  • Reduced weight
  • Floating blade design eliminates thermal distortion
  • Upstream and downstream blades may be supplied in different materials
  • Suitable for cladding with alloy stainless steels
  • Low pressure drop
  • Insulated blade design available
