KDB ATEX 17.0616, EU Declaration of conformity 001-01-2017.

Cut-off dampers of fire resistance independent from direction of air flow and of installation side.

Dampers for rectangular and rounded ventilation ducts.

 

mcr FID S/S p/P, mcr FID S/S p/O cut-off dampers are designed for installation in general ventilation systems, at the point of penetration of these installations through building partitions.

During fire, they allow to maintain fire resistance of the building partition through which ventilation and air conditioning ducts run. They also prevent propagation of fire, smoke and fire gases to the safe part of the building.

When made for potentially explosive zones (EX variant), the dampers may operate in zone 1 (risk of explosion of gases inside and outside of ventilation ducts) and zone 21 (risk of explosion of dust outside ducts). The dampers conform to the requirements of group II category 2G and -/2D.

  • damper reinforced with insulating interlayer
  • bracing-reinforced barrier - increased mechanical strength
  • large dimensions – up to 1.8 m2
  • installation in walls and ceilings,
  • installation outside building partitions
  • installation in batteries (damper sets)
  • optional making in EX variant
  • operating reliability up to 10 000 cycles

Dimensions for rectangular dampers:

  • nominal width from 200 to 1500 mm
  • nominal height from 200 to 1500 mm
  • maximum area of section of single damper not larger than 1.8 m2

Dimensions for rounded dampers:

  • nominal width from 125 to 630 mm

Apart from standard dimensions, dampers can be customized to any size within the specified ranges.

 

Control:

  • RST mechanism - thermal trigger 72oC (optionally 95oC) on partition, actuating spring, manual arming;
  • RST/WK1 mechanism - thermal trigger 74oC (optionally 95oC) on partition, actuating spring and limit switch, manual arming;
  • RST-KW1/S - integrated mechanism - thermal trigger 74oC (optionally 95oC), in the mechanism, actuating spring, manual arming;
  • RST-KW1/S/WK1 or WK2 mechanism – integrated mechanism - thermal trigger 74oC (optionally 95oC) in the mechanism, actuating spring, one or two limit switches, manual arming;
  • RST-KW1/24l mechanism – integrated mechanism - thermal trigger 74oC (optionally 95oC) in the mechanism, actuating spring, one or two limit switches, electromagnetic trigger responding to current impulse, U=24V DC manual arming;
  • RST-KW1/24P mechanism – integrated mechanism (thermal trigger 74oC (optionally 95oC) in the mechanism, actuating spring, one or two limit switches, electromagnetic trigger responding to power decay, U-24V DC, manual arming;
  • Belimo type mechanism – actuators series with return spring and thermoelectric trigger (BFL, BFN, EXBF series).

The use of MP230/24 element enables the powering/triggering of KW1 mechanism with 230V AC voltage.

Making variants:

  • mcr FID S/S [BFL…-T, BFN…-T, BF…-T, EXBF] – fire cut-off damper for ventilation ducts, with electric actuator with return spring with thermoelectric trigger - closing and opening of damper using actuator
  • mcr FID S/S [RST] – fire cut-off damper for ventilation ducts with spring actuator and thermal activator
  • mcr FID S/S [RST/KW1] – fire cut-off duct for ventilation ducts with spring actuator with integrated thermal activator; electromagnetic activator and limit switches available optionally

Additional equipment:

  • WK1 – limit switch (closed barrier signal)
  • WK2 – limit switch ( damper open/shut signal)

mcr FID S/S dampers can be used as pressure-relief dampers in gas extinguishing systems; in this case they are equipped with actuators without thermoelectric or thermal activators.
