mcr WIP/S - multi-blade cut-off fire damper for comfort ventilation systems

Fire resistance class: EI60(ve i↔o)S, E120(ve i↔o)S

Certificate of constancy of performance 1396-CPR-0097.

Dampers certified for conformance with EN 15650.

Dampers are classified as per EN 13501-3 and tested according to EN 1366-2.

Declaration of performance 001-05-CPR-2015.

Optional EX making of dampers (as per ATEX directive) for applications in explosion hazard zones.

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.

Fixed, narrow damper thickness, regardless of B x H dimensions.


mcr WIP/S multi-blade cut-off dampers are designed for use in general ventilation installation, in points 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.

  • small thickness of damper - 140 mm
  • cut-off barrier does not protrude outside the damper body, regardless of damper dimensions
  • large active damper in the multi-plane dampers segment
  • possible installation in a partition, on a duct ended with a duct cover
  • optional making in EX variant
  • optional making of dampers with penetrations for rounded ducts

    operating reliability up to 10 000 cycles

Dimensions for rectangular dampers:

  • nominal width from 120 to 1000 mm
  • nominal height from 160 to 1000 mm
  • maximum area of section of single damper not larger than 1 m2

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

 

Control:

  • Belimo type mechanism – actuators family with return spring and thermoelectric trigger (BF, BFL, BFN, EXBF series).

Detailed technical data are contained in the technical catalogue.

Making variants:

  • mcr WIP/S [BF…-T, BFL…-T, BFN…-T] – fire cut-off damper for ventilation ducts, with actuator with return spring - closing and opening of damper using actuator
  • mcr WIP/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:

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

mcr WIP/S dampers are particularly useful in cases when a silencer, a pipe elbow or an air flow grate is designed in the system behind the damper.
