Power Damper Services was approached to advise why their operators were continually having problems & down time with the dampers on their GT system. It was immediately apparent they were using the dampers for a completely wrong application.

Guillotine dampers are fine for shutoff duties, but not suitable for control.

We recommended the guillotine dampers be replaced by Twin Louvre dampers that would provide good isolation and good control of the flow medium.

After further consultation, PDS supplied the new dampers and a satisfactory conclusion obtained.
