SC / SCV

SC / SCV

The SC dampers are fire shutters designed for installation directly into circular ducts. The SCV are fire dampers with disc valves designed for circular ducts and suitable for both air inlet and outlet. The fire dampers have a thermal fuse that melts and closes the damper when the temperature exceeds 72 °C. The fire resistance of the barrier is at least EI60S/90/120 (depending on the wall construction and installation method). The fuse is replaceable and can be ordered separately.

 

BX-1H

BX-1H

The BX-1H circular fire disc valves are designed for installation in vertical fire partitions or at the beginning of ducting routes. The regulating disc allows the air flow regulation and the locking is provided by a lock nut. In case of a fire, when the temperature exceeds 72 °C, the BX-1H valve closes and separates adjacent fire compartments. The BX-1H fire valve is classified according to ČSN EN 13501-3+A1:2010 as El 60 S. The design of the valve complies with ČSN EN 15650:2010. A 35 mm long sleeve (mounting ring) is standardly included (67, 120 or 150 mm long sleeves are available on request).

PKI-C

PKI-C

The fire cartridge damper PKI-C is a fire shutter in the round ventilation duct with the fire resistance classes EI60S, EI90S and EI120S. The fire damper PKI-C is composed of a galvanized steel sheet, calcium silicate plate, anti-fire graphite laminate, polyurethane foam, ethylene-propylene rubber, copper sheet metal, low-melting solder in a fail-safe device (Sn-, Bi- or Pb-based) and of a surface powder paint.

 

PKI-S

PKI-S

The PKI-S square fire damper is a fire shutter in HVAC ducts. The damper blade closes the HVAC square duct on the basis of a mechanical, thermal or electric signal and therefore prevents fire, heat and smoke from spreading. The fire dampers are certified in compliance with EN 15650, tested in compliance with EN 1366-2 and classified in compliance with EN 13501-3. The fire damper housing and auxiliary structures are made of galvanized steel sheet. On request, it is possible to deliver the construction and housing made of stainless steel sheet A316L or A304.

The PKI-S fire damper blade consists of calcium silicate asbestos-free plates and is placed in a protective frame. The passive tightness of the fire damper against smoke transmission is ensured by a rubber seal. The active tightness against smoke and heat transmission during fire is ensured by a fire seal Intumex. To put the damper into the „CLOSED“ position, the damper is equipped with a release mechanism „Manual“ - basic design with a fuse, alternatively with an electromagnet or with a servo drive. The panel with the release mechanism of all fire dampers is removable and at the same time interchangeable with a differently equipped panel, e.g. instead of the manual control mechanism with a servo drive mechanism etc. All fire dampers are equipped with at least one inspection opening.

Manual release mechanism

  • ZV - The basic equipment of the fire damper (standard model) is a manual mechanism with a trigger spring. The spring is released when the fuse is disconnected as the temperature reaches 72 - 74°C (100°C on request). The damper closes within 10 s after the fuse has been disconnected.
  • DV1-2 ZV + two limit switches signalling the damper position „OPEN“ and „CLOSED“, 24 V (AC/DC) / 230 V (AC).

FGS

FGS

The FGS anti-fire ventilation grid is designed to divide fire sections and to prevent toxic gases, fume and flames from spreading. The FGS anti-fire ventilation grid is an element of the passive fire protection. The FGS grid is tested in compliance with EN 1364-1, ETAG 026 part 4 and PREN 1364-5:2014 and classified in compliance with EN 13501-2:2017.

The FGS anti-fire ventilation grids are designed for fixed installation in a fire separation construction with no connection to a follow-up HVAC duct. The FGS anti-fire ventilation grids are available with manual control or with a servo drive.

The manually controlled anti-fire grids

The FGS anti-fire grid release mechanism is activated when the ambient air temperature reaches 74°C. In case of fire, the grid automatically closes within 10 s after melting of the thermal fuse. When the grid is closed, the blades remain locked in the closed position and can only be opened manually. Anti-fire grids equipped with microswitches are available on request.

The anti-fire grids with the servo drive

The FGS anti-fire grids with the servo drive are standardly equipped with a thermo-electric fuse, which activates the closure of the blades when the ambient temperature reaches or exceeds 72 °C. The power supply circuit is interrupted and the spring closes the blades within 20 s. All servo drive-operated grids are equipped with microswitches signalling the blade position. Grids with power supply and with a communication unit can be available on request (activation mechanism DV9-T-ST). The FGS ventilation grid is equipped with a spring-actuated servo drive that closes the anti-fire grid on the basis of a command from the BMS (EPS) system or when the thermo-electric fuse has melted.
