mcr WIP LD - MULTI-BLADE SMOKE CONTROL DAMPER FOR MULTI-ZONE FIRE VENTILATION SYSTEMS

mcr WIP LD /V, mcr WIP LD /V-M smoke dampers consist of a casing with a rectangular cross-section, multiple moving damper blades – louvers rotating around their own axes – and a remotely activated trigger and control mechanism, which is installed inside the damper clearance. The damper casing is made of galvanized steel sheets or stainless steel sheets. The damper is also provided with a connection flange on one side. The other end is the so-called “bare-end”. The damper casing total length is 350 mm. Damper louvers are made of galvanized steel sheets or stainless steel. The damper blades revolve on their own axes, which consist of steel pins. A ventilation gasket is provided on the blades to ensure that the damper is “cold” sealed.

The mcr WIP LD smoke dampers are intended for installation in manually or automatically operated fire ventilation systems. The devices are used in fire ventilation systems or in mixed fire and comfort ventilation systems (smoke evacuation or air supply systems). The dampers prevent fire, smoke and fire gases from spreading to the adjacent compartments. During normal system operation,  the damper blade is closed. The fire damper blade in the fire compartment is opened, whereas in other areas the blades are closed.
