protection of filters, mixers, cyclones, mills, dryers and other process equipment as well as preventing the transfer of explosion effects to the rest of the plant area or equipment.
an ExKop system consists of a QV quench valve and a control unit,
the QV quench valve (membrane made of rubber or EPDM, bi-directional operation) is activated by 6 bar compressed air from the plant’s compressed air system,
if an explosion occurs in the processing equipment, it is vented via a membrane or an Eco-Q-Rohr system,
when an explosion occurs the control unit receives a signal from the membrane’s burst sensor (including Eco-Q-Rohr), a pressure sensor, or a spark sensor (installed in the duct),
suitable for dusts with a Kst value of up to 200 bar m/s, max. explosion pressure – 10 bar,
the value of reduced explosion pressure of up to 1 bar g,
DN 80 to DN 500 design, mounting distance of QV valve from the protected equipment: 5-7 m (7-9m, DN 250 to DN 500),
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).
control unit for an explosion protection system (HRD containers, pressure and infra-red detectors),
this single-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.
an element of the protection system for vessels and process equipment where flammable and combustible substances are handled in explosive concentrations,
identification of explosion pressure rise, in its early stages, triggers the activation of the explosion protection system,
designed for assembly on process vessels, ducts and pipelines in which ST1-ST3 class dusts are present as well as for gases and hybrid mixtures across all industries.
a protection system element to be installed in ducts and pipelines connected to bucket conveyors, filters, tanks and other equipment for immediate detection of explosion events,
identification of ignition sources such as flame, heat and sparks in order to activate the protection system on process lines and ducts connected to protected equipment,
quick detection of an explosion propagating through ducts and piping in order to activate the protection system,
to be used in enclosed areas without daylight access.
