The Process exhaust air is sucked at a pressure of 700m barg at the process temperature using an insulated heated sampling probe. The gas sample passes through this tube which has a high enough temperature maintained to keep the sample air above its dewpoint temperature and avoid any condensation to ensure accurate measurement. The sampling tube is ATEX certified for zones 1/2 & 21/22..
The quick closing valve is part of an active explosion isolation system. In the event of ignition, it is activated by solenoid valves. Air flows out of a compressed air reservoir into the drive cylinder, closing the slide valve within milliseconds. Both the flames and the spread of pressure are effectively stopped. After having been triggered, the slide valve can be reactivated without needing a repair, and because of its non-destructive operation it can be validated at any time.
The Explosion Suppression System AIS (Advanced Inerting System) from ATEX gives protection where combustion and the subsequent explosion pressure could exceed the strength of your production facility. The combustion reaction is detected at its very early stages and its propagation extinguished. The growing explosion is suppressed by a quick release of an appropriate extinguishant into the combustion zone. The goal is to restrict the expansion of the explosion and thus to keep the consequences to a minimum.
The ACOM Detection System continuously analyses in and outlet airstreams of a drying process for volatile pyrolysis matter, thus detecting the earliest signs of thermal decomposition and the formation of hot spots, which means that they detect self-ignition processes whilst they are still forming and ideally long time before they become a Fire and/or Explosion Hazard.
The Q-Pipe (now also available as a Q-Box) Flameless Vent System was developed in response to a specific need, i.e. explosion venting inside buildings. Traditional explosion venting technologies require a safe venting area (usually outdoors), where there is no risk of secondary explosions or harm to personnel. Explosion vented plant has to be ducted out to a designated (external) safe area (usually within 3 to 6 metres). The only alternative was to strengthen vessels to withstand greater explosion pressures and/or to install relatively expensive explosion suppression systems.
To meet the need of the powder industry, ATEX developed its cleanout technology in a passive oriented system. A valve that could meet the product flow requirements of today’s processes. The system would by Patent Pending Design clean out the isolation seal eliminating consideration of powder being compressed by the closure and allowing the flame to pass.
Explosion diverters provide a cost effective means of mitigating the propagation of an explosion through ductwork. The relief vents are fitted into connecting pipes to separate subsequent apparatus in the event of a hazard. If an explosion happens in the equipment, the flat closes immediately, and disconnects the area con-cerned from the other apparatus. Transmission of the explosive pressure is interrupted, and the propa-gation of sparks therefore largely avoided. With the pressure relief vent you therefore protect your pipelines effectively from explosion transfer.
