High Performance Guillotine Dampers

Our organization specializes in importing, supplying, and trading of High Performance Guillotine Dampers in Mumbai, Maharashtra, India. The guillotine damper, or slide gate damper as it is sometimes called, has the main function of process isolation and isolation of equipment to permit inspection, maintenance, or repair. Guillotine dampers are specified for bypass ducts. Guillotine dampers are generally used when space limitations don't allow for longer damper casings. The isolators provide a 100% gas tight isolation in terms of UVV regulations. The sealing is hermetic and compares to that of a blind flange connection. The co-axially movable ceiling frame is retractable before the blade can be driven in and out of the duct. The ceiling frame can be hydraulically, pneumatically or electrically operated.

Guillotine dampers are mainly used to isolate one area of the installation in order to perform inspections and repairs (they are usually on/off type, either being completely open or completely closed, but they do not regulate flow) and are sometimes specified for bypass conduits. They provide 99% air tightness with a Metal to Metal step seat.

Advantages

100% isolation possible.
Low pressure drop even when the damper is wide open when the process.
