PKI-C

The PKI-C cartidge fire dampers are fire shutters in HVAC ducts with classes of fire resistance EI60S, EI90S and EI120S. The PKI-C fire dampers are equipped as standard with a fuse which closes the damper when the temperature reaches 72 °C or they can be equipped with one limit switch (DV-1), or two limit switches (DV1-2), which signal the status of the damper position.

The PKI-C fire damper consists of galvanized steel sheet, calcium-silicate plate, graphite fire-retardant laminate, polyurethane foam, ethylene-propylene rubber, copper sheet, low-melting solder in a fuse based on Sn Bi Pb and surface powder paint.

The PKI-C dampers are no longer available and are replaced by F-C2 fire cartridge dampers.
