Circular Smoke Control Damper SDI
SDI is a motorised circular heat-insulating smoke control damper that prevents fire and smoke from spreading in ventilation ducts. If the power in the motorised actuator is switched off by the
system, the blade closes automatically (failsafe closed). A double-sealing solution closes the duct, effectively preventing the spreading of flue gases in the ventilation ductwork when the fire damper closes. The flexible seal of the double-sealing system operates at lower temperatures, while the graphite mass seal expands to insulate the system at temperatures above 150 ºC.
