Product Profile of Fire Dampers
TSC Group Of Industries offers Fire Dampers. TSC Group Of Industries manufactures various engineering equipments. Fire Dampers are provided on air / gas ducts to control flow under normal circumstances and to isolate areas connected by duct from the fire affected areas. Fire Dampers are manufactured with single flap / multi louvers. The louvers are connected through suitable linkage to a controlling actuating device such as electrical actuator / solenoid valve / pneumatic cylinder / fusible link. Louver / flap shaft are provided with bearings with greasing facility to enable smooth rotation. These louvers / flaps are made of mild steel. The louvers /flaps are designed in the form of a box and are sandwiched with high grade insulating material which can withstand 9800 degree C for period of 90 minutes. They conform to UL - 555, thereby acting as effective barrier in closed position to the flame path between air duct and fire effected area.
