GUILOTINE DAMPERS
Guilotine Dampers are generally used where high efficiency isolation is required, or in cases where it is inadvisable to have any blades in the gas stream, due to abrasion - they are not suitable as control dampers.
Various sealing arrangements are available, including purge air arrangements to provide total isolation of process gas.
These dampers are of extremely robust construction, with all components requiring maintenance placed on the outside, permitting maintenance to take place whilst the plant is on line.
The preferred blade drive mechanism is by heavy duty chains and sprockets, which have proved to be totally reliable-even in instances when the dampers are only operated once per year during maintenance shut downs.
Materials of construction, refractory lining, if required, and drive configurations are selected and designed to suit the application and customer requirements.
