KWP-Ex cut-off fire dampers (in explosion-proof execution)
The fire dampers in explosion-proof execution of KWP-Ex type are designed for the assembly in the ventilation systems as the closing divisions, separating the fire zone from the remaining part of the building.
The devices of KWP-Ex type provide the high safety level and are designed to be used in the places, in which there is possibility of the explosive atmosphere occurrence, caused by gases, vapours, mists and air-dust mixtures.
KWP-Ex dampers are designed and certified according to the directive ATEX 94/9/EC as the devices of group II category 2 designed to be used in the explosion hazard zones 1,2,21 and 22.
The damper fire-proof efficiency was proved with the testing pursuant to the standards: EN ISO 80079-36:2016 and EN ISO 80079-37:2016 and confirmed by the certificate JSHP 22 ATEX 0017X issued by J. S. Hamilton Poland Sp. z o. o. No. AC 149.
KWP-Ex dampers have the ATEX marking: II 2G Ex h IIC T6…T5 Gb and II 2D Ex h IIIC T80°C…T95°C Db. Electrical components are ATEX marked according to their certificates.
These dampers are intended to install in horizontally (in walls) and vertically (in ceilings). They can be installed in rigid and flexible building partitions.
The damper is designed, manufactured and tested in accordance with the requirements of the following standards: PN EN 15650 and PN-EN 13501-3. The effectiveness of the dampers is confirmed by tests according to the PN-EN 1366-2 standard.
