Thermal fuse - Import export

The FDA12 round fire dampers are designed for use in general ventilation systems to seal off smoke and fire between adjacent fire partitions. The fire dampers are classified according to EN 135013+A12010P (Fire classification f construction products and building elements). The fire resistance was tested as per PNEN 136622001P (Fire resistance tests for service installations Part 2 Fire dampers). The entire manufacturing process meets the requirements of EN 156502010. The FDA12 fire dampers can be installed in horizontal and vertical fire partitions to provide fire resistance of EI 120 (ve ho i↔o) S (which may depend on the actual fire resistance of the partition). The fire dampers are available in the nominal diameter sizes DN100, DN125, DN160, DN200, DN250, and DN315. All fire dampers have a pull spring control gear and a fusible thermal trip (in FDA12T) or a returnspring actuator coupled with a thermal trip (in FDA12M).

The fire dampers are manufactured in the following nominal sizes DN100, DN125, DN160, DN200. The fire dampers are equipped with a thermal fuse mechanism ensuring the damper switch to the safe position in case of reaching an ambient temperature equal to or higher than 72°C. The fire dampers allow using limit switches signalling closed position of the damper blade (1 limit switch) or blades (in case of using 2 limit switches). The casing is made from galvanised steel sheet; the fire damper blade is made from a silicate cement board.
