at the moment of an explosion the door is released from its snap fasteners and the lid of the explosion door is opened,
the door’s recoil force is absorbed in over 80% by an air cushion created between the safety door and steel baffle plates,
the door’s residual kinetic energy is used for bouncing the plate back to position, which ensures its automatic re-closing after the explosion is vented and prevents air intake,
the design ensures that the load is not transmitted to the supporting structure, which allows for direct on-roof installation without the need for additional reinforcements,
the door’s spring snap fastener allows the initial door opening pressure to be adjusted (0.1 bar g by default),
every instance of door opening can be signalled by a limit sensor,
the vacuum that is created in the protected vessel after an explosion (quick cooling of gas after an explosion), which may cause the vessel’s collapse due to implosion, is eliminated by vacuum breakers mounted on the flange body, which allow the air to be sucked in when vacuum is created,
TT-Uni-K door and vacuum breakers can be equipped with an electric heating system.
control unit for an explosion protection system (HRD containers, pressure and infra-red detectors),
this multi-zone control unit performs the following control and diagnostic functions: system monitoring, distribution of stored energy for actuation of explosion-protection equipment and on-line verification of the status of an explosion suppression system,
its modular design allows selective system activation (e.g. system activation for a single piece of equipment in which an explosion occured).
One Earth-Rite Multipoint unit can monitor up to 8 potentially isolated conductive components on processing machinery engaged in powder processing operations within zoned or classified areas,
Applications with items of process plant incorporating sections, which must be removed periodically for cleaning, product discharge or other purposes (whose removable parts may become isolated conductors), including systems for dust control, grinding, diminution, powder handling, emptying/filling of silos and tanks, and driers.
protection against propagation of explosion from processing equipment (e.g. mills) to silos, filters or electrostatic precipitators by controlled venting of explosion effects to the atmosphere (explosion isolation) and/or,
protection against explosion propagation from silos, filters or electrostatic precipitators to the plant’s process equipment by controlled venting of explosion effects (explosion isolation).
