A Single louvre damper placed at the intersection of inlet and by-pass lines, if one line is closed the other will be in open condition or vice versa.

Expensive design comparing with T-Duct dampers. Actuators are too heavy.

Very low pressure drop.

100% isolation with Purge air system or opening to atmosphere is possible.

Rectangular in shape.

It can be mounted in horizontal.

• 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.
