Atexi tuletõkkesektsioonid kujutavad endast passiivset tulekaitset, mis on kavandatud sektsioonide abil, et takistada mürgiste gaaside, suitsu ja tule levikut. Standardsed tuletõkkesektsioonid on projekteeritud ja sertifitseeritud vastavalt standardile EN 15650 ning testitud EIS-kriteeriumide alusel vastavalt standardile EN 1366-2. Tuletõkked koos nende paigaldamisega moodustavad lahutamatu osa tuleohutuspiirangust.

Käesolevat Atexi versiooni on muudetud direktiiviga 2014/34/EL, milles on sätestatud tehnilised nõuded plahvatusohtlikus keskkonnas kasutamiseks mõeldud seadmetele ja kaitsesüsteemidele.

Atex fire dampers represent passive fire protection, designed with the help of compartmentalization to prevent the spread of toxic gases, smoke and fire. Standard fire dampers are designed and certified in accordance with EN 15650 and tested for EIS criteria according to EN 1366–2. Fire dampers together with their installation form an inseparable part of fire resistivity rating. This Atex version is enhanced by 2014/34/EU directive, which set out the technical requirements for equipment and protective systems intended for use in potentially explosive atmospheres. Atex fire dampers are designed for group II category 2 G and 2 D against the ignition of gas explosion group IIB and dust explosion group IIIB, temperature class T100 °C (Activation type H2-EX only T6) and Equipment Protection Level Gb and Db according EN ISO 80079-36.2016.

• Suitable for Gas and Dust explosive atmosphere

• Two inspection openings for all sizes greater than 200x200 mm

• Great variety of installations rated up to EI120S

• Multiple FDS-EI90S damper installation - up to 4 dampers with a maximum size of 3260 × 2060 mm

Atex fire damper with a maximum fire resistivity of 120 minutes and a single body design. Size range from 100x100 up to 1200x800 mm.

Atex fire damper with a maximum fire resistivity of 90 minutes. Construction of two sheet metal bodies, conductively connected through a calcium-silicate frame. Width greater than 1200 mm and/or height greater than 800 mm up to a maximum size of 1600x1000 mm.

Atex fire damper with a maximum fire resistivity of 120 minutes. Construction of two sheet metal bodies, conductively connected through a calcium-silicate frame. Width greater than 1200 mm and/or height greater than 800 mm up to a maximum size of 1600x1000 mm.

By default, all manually operated fire dampers are supplied with a hand crank, optionally with micro switches. In case of fire, the fire damper closes automatically after the melting of the thermal fuse. After the closing of the damper blade, it is mechanically locked in the closed position and can only be opened manually. The actuating mechanism is activated when the temperature of the air in the duct reaches 74°C and the damper closes within 10 seconds after the melting of the fuse.

Atex fire damper with an activation mechanism with a conductive plastic cover, manual crank and with a spring return release mechanism activated by a fusible thermal link set to 74°C (on demand 100°C).

 - Zone: 1, 2 (Gb, limit T6), 21, 22 (Db, limit T85°C)

Atex fire damper with an activation mechanism H0-EX + open and closed indication with AC 230 V or AC/DC 24 V contact Atex rated switches. Atex temperature class reduced to T85°C in Db and T6 in Gb.

By default, all actuator operated fire dampers are supplied with an actuator with microswitches. A fire damper equipped with a spring return actuator can be closed with command from the building management system, or after the breaching of the thermoelectric fuse. Actuator operated fire dampers are standardly equipped with a thermoelectric fuse that activates the closing of the damper after the reaching or exceeding of the ambient temperature of 72°C. The actuator power circuit is interrupted and its spring closes the damper blade within 20 seconds.

Atex fire damper with an activation mechanism with Atex rated Schischek ExMax spring return actuator (with universal supply unit 24…240 V AC/DC) with an electro-thermal fuse at 72°C and auxiliary switches.

Atex fire damper with an activation mechanism with Atex rated Schischek RedMax spring return actuator (with universal supply unit 24…240 V AC/DC) with an electro-thermal fuse at 72°C and auxiliary switches.

Atex fire damper with ExBox-BF terminal box and an activation mechanism with Atex rated Schischek ExMax spring return actuator (with universal supply unit 24…240 V AC/DC) with an electro-thermal fuse at 72°C and auxiliary switches.

Atex fire damper with ExBox-BF terminal box and an activation mechanism with Atex rated Schischek RedMax spring return actuator (with universal supply unit 24…240 V AC/DC) with an electro-thermal fuse at 72°C and auxiliary switches.

Atex fire dampers have casings made from galvanized sheet metal. Blades from non-asbestos insulants have a rubber seal for cold smoke and an intumescent seal, that expands in a fire situation. All moving parts are conductively connected to eliminate electric charges.

The product contains galvanized sheet metal, calcium silicate board, fireproof carbon fiberglass, polyurethane foam and ethylene-propylene rubber. These are processed in accordance with local regulations. The product contains no hazardous substances, except for the solder in the thermofuse, which contains a milligram of lead.

• IKOWS-FD: Installation Kit for Installation on a Wall and out of a Wall Using Promatect Boards

• The fire damper is suitable for the use with the ambient temperature Ta = 0°C/+60°C. In case of additional electrical equipment (limit switch, temperature sensor, servo-drive) the temperature range is reduced according to the range of the used device.

• The electrical devices installed together with the damper must have the type of protection corresponding with the defined zone.

• The temperature class of the equipment is dependent on the temperature of the flowing medium according to the table:

The maximum temperature of flowing medium 60°C:

• Initialization temperature of heat fuses: ≥ 72°C

The maximum temperature of flowing medium 85°C:

• Initialization temperature of heat fuses: ≥ 100°C
