Butterfly dampers are single louvre dampers used for isolation and control application.

100% isolation is possible in butterfly dampers.

Duct can be Circular or Rectangular in shape.

It can be mounted in horizontal, vertical or inclined orientation.

Ø150mm to Ø3000mm butterfly dampers can be manufactured.

• Our Speciality Dampers

  Dampers for FGD/SCR systems.

  Dampers for Sulphuric acid plants.

  Dampers for high temperature applications.

  Dampers for Saline/ Offshore environment.

  Dampers for corrosive and highly abrasive flow medium.

• Our Specialities

  Self aligning ARVIS bearings and DODGE graphite sleeve bearings.

  Self aligning and adjustable Heavy duty tie rods for linkages.

  No landing bar in between blades, So minimum pressure drop.

  Mechanical glands for toxic gas applications.

• Testing of Dampers

  All dampers are manufactured and tested in-house prior to dispatch.

  Sealing efficiency On Cross Sectional Area is demonstrated by Feeler gauge method.

  Sealing efficiency On Flow can be demonstrated by simulating site condition.
