Double-wing smoke dampers

Dimension

From 160 x 160cm to 300 x 300cm

Certificate

Declaration of Permanent Performance with CE mark 1488-CPR-0042/W according to EN 12101-2:2003;

Characteristics

Smoke dampers are an important component of gravitational smoke extraction, used to vent harmful substances generated during a fire. Thanks to its sunlight-permeable cover, it can also serve as a rooflight. Due to the performance characteristics, they are designed for installation on flat roofs (up to 15°). Smoke dampers are widely used in large-scale facilities: production halls, logistics centers, warehouses, sports facilities, skyscrapers, shopping malls. They can be made in two variants: single-wing and double-wing

Technical description

Smoke damper base:

composed of four segments made of galvanized steel sheet with a thickness of min. 1.25 mm. Base height adapted to the roof structure and technical requirements, from 300 to 1000 mm. Standard heights: 350, 500, 750 mm. Smoke damper bases require a support structure around the perimeter.

Types of bases:

Cover:

  • Cellular polycarbonate (PC) - thickness of choice 10, 16, 20, 25 mm. The outer layer of polycarbonate covered with a coating containing a UV filter;

  • Fire retardant Kera Fire Protect panel - BROOF(t1) class external fire retardant, selectable thicknesses of 21, 27, 33 mm;

  • Domes - single or multilayer, material of choice: acrylic / solid polycarbonate;

  • translucency - klar (transparent) or opal (milky, standard for fire retardant Kera Fire Protect panels);

  • Solar Control - chambered polycarbonate covered with a special additional coating that allows to control the amount of solar radiation passing through the panel. As a result, rooms are better protected from excessive heat in the summer.

Actuators:

Two types of actuators are used to open smoke dampers:

  • Electrical - 24 VDC with a current of 2.0 A to 8.0 A;

  • Pneumatic - one- or two-way actuators using CO2 cartridges. In the case of double-wing smoke dampers, two actuators are installed
(one per wing).

Smoke deflector:

An additional element that increases the smoke damper's active smoke extraction area, made of galvanized steel sheet.

Directional nozzle:

An additional element that increases the smoke damper's active smoke extraction area, made of sheet metal.

Technical parameters

  • High values of smoke extraction parameters specified in the Deklar ation of Permanent Performance with CE mark 1488-CPR-0042/W according to EN 12101-2:2003;

  • Re 1000 - reliable operation during 1000 cycles of opening and closing the smoke damper sash to the fire position. This means 1000 times activation of the trigger system without loss of efficiency;

  • SL 250/SL 550/SL 650/SL 900 - reliable operation under load of 250 N/m2, 550 N/m2, 650 N/m2 or 900 N/m2 respectively, opening time less than 60 s.

Essential dimensions and characteristics in accordance with the harmonized standard

  • T (00) - products of this class are considered suitable for use in building structures with temperatures higher than 0 °C;

  • WL 1500 - wind load resistance equal to 1,500 Pa, opening time less than 60 s;

  • B 300/B 600 - temperature resistance, respectively: 300 °C and 600 °C;

Additional options:

  • Ventilation - a ventilation system is additionally mounted to the dampers (dual function damper), which allows natural and economical ventilation of rooms on a daily basis. If the smoke damper is equipped with an electric drive, the smoke extraction and ventilation function is operated by the same 24 VDC actuator, while in the case of pneumatic control of the system, an additional actuator powered by 230 VAC is installed or the pneumatic actuator is bi-directional. As a standard for a two-wing smoke damper, one actuator is used for the ventilation function (one of the wings is opened);

  • Anti-drop grating;

  • The inner side of the base can be painted in any RAL color (standard 9010, 9002 or 9003);

  • Retrofitting the smoke damper with a smoke and ventilation system, such as a smoke control unit (Actulux, AFG), smoke detectors, alarm buttons.

Additional option

  • Up to 10-year warranty on polycarbonate panels and airtightness

  • 2 year warranty on actuators

  • Designing and optimizing solutions tailored to customers' needs

  • Support in the preparation of technical documentation

  • providing technical advice at every stage
