KWP-P-E type fire dampers are intended to installation in smoke and heat control systems, acting as protection against spreading of fire, temperature and smoke. During normal operation of the system , the flap of the KWP-P-E damper is in the open or closed position.Assembly and operation of fire dampersIn case of fire, the actuating system opens the dampers which operate in the fire detection zone (dampers in other zones move to the closed position). These dampers are nonsymmetrical, intended for vertical installation (in walls). They can be also installed in rigid building barriers.Effectiveness confirmed by researchThe damper is constructed, manufactured and tested in accordance with the standards: PN-EN 12101-8 “Smoke and heat control systems – Part 8: Smoke control dampers” and PN-EN 13501-4 “Fire classification of construction products and building elements Part 4: Classification using data from fire resistance tests on components of smoke control systems”. Sensitivity of the dampers is confirmed by tests in accordance with the standards: PN-EN 1366-2 and PN-EN 1366-10 “Fire resistance tests for service installations- Part 2: Fire dampers, Part 10: Smoke control dampers”.Construction of fire dampersThe damper is composed of two bodies made of galvanized steel, which are separated with insulating dividers made of 40 [mm] thick, fire-resistant material. Inside the damper there is a flap, which movement in closed position is limited with stop bar. The axles of the flap cooperate with slide bearings built in the insulating dividers. The closing of the flap is realized by the system of the flexible connectors.KWP-P-E type fire dampers are based on one unified body. The damper is optionally provided with two inspection holes at the top and the bottom, which makes it is not necessary to install inspection covers in the ducts before the damper, for making the periodic inspection and testing. There is also no need to specify the service side.
