fire dampers: rectangular dampers

mcr WIP

mcr WIP is a multifaceted shut-off damper for fire ventilation systems and a transfer damper.

versions:

– shut-off – S

– for fire ventilation systems (smoke ventilation) – V

– for dual-function channels (mixed systems) – M

– transfer – T

purpose:

– mcr WIP / S fire dampers with a thermal release are designed for installation in general ventilation installations, in the place where these installations pass through building partitions. The dampers can be mounted at the end of the ventilation system.

– mcr WIP / V flaps are made without a thermal release. These are flaps used in fire ventilation systems.

– mcr WIP / M flaps are designed for installation in system installations, where ventilation ducts fulfill two functions – general ventilation and ventilation exhaust ventilation, at the place of passing these installations through building partitions. These dampers are not equipped with thermal triggers.

– mcr WIP / T flaps are designed for transfer housing. In this case, the damper is installed in the wall of the fire separation without ducts.

drive and release systems:

– MERCOR type KW1 release and control mechanism with integrated 72 ° C thermal trigger.

– MERCOR release and control mechanism type KW1 without thermal trigger 72 ° C.

In addition, the mechanism KW1 (with thermal release and without thermal release) can be equipped with a 24V DC or 230V AC solenoid release, limit switches for signaling the position of the fire damper partition, actuator for setting the damper in the MERCOR KW wait function,

– MERCOR triggering and control mechanism type RST (without integrated thermal release) equipped with a spring. The thermal release is mounted in this case outside the flap mechanism, on the partition itself,

– triggering and control mechanism in the form of an axial actuator with a return spring series BF, BLF, 229, 239 or an actuator series EXBF for 24V AC / DC or 230V AC with a thermoelectric trigger 72 ° C,

– release and control mechanism in the form of an axial actuator without a BELIMO BE-series return spring for 24V AC / DC or 230V AC voltage without a thermoelectric release.

– triggering and control mechanism in the form of an axial actuator with a return spring of the following type: SFL1.90T / 14 (24V AC / DC) SFL2.90T / 14 (230V AC) produced by Jovent.

Optionally thermal or thermoelectric triggers with different operating temperature can be used in the mcr WIP flaps.

Fire resistance: EIS 60, EIS 60 AA, ES 120

The mcr WIP shut-off valves are produced in the following dimensions: width from 120 to 1000mm, height from 200 to 1000mm. In addition to standard dimensions, it is also possible to make indirect dampers. The maximum cross-section area of mcr WIP flaps is: 1 m2. The minimum flap area is 0.019 m2.

Note! The mcr WIP flap is available only on request. Detailed information is available from our sales representatives
