Function and Description

Protection against atmospheric deflagration and endurance burning

The PROTEGO® EB end-of-line deflagration Deflagration Explosion propagating at subsonic velocity (EN 1127-1:1997). flame arrester provides protection against atmospheric deflagration and long-lasting stabilized flames, called endurance burning. The device Device A device is a pipe component that influences the media flow by opening, closing, or partially shutting off the flow channel or by dividing or mixing the media flow. is typically installed on vent lines of vessels and plant equipment Equipment Machines, appliances, fixed or mobile devices, control parts and accessories, and warning and prevention systems, whether separate or combined, intended for the generation, transfer, storage, measurement, control, and conversion of energy, and for the processing of materials, which have their own potential source of ignition and may cause an explosion. which is not pressurized. The device prevents flame transmission from endurance burning or atmospheric deflagration into the vessel Vessel Container or structural envelope in which materials are processed, treated or stored. or plant.

Main component - PROTEGO® flame arrester

The PROTEGO® EB-IIA consists of the PROTEGO® flame arrester unit (1) and the metal weather hood (2). During normal operation, the metal weather hood is in a closed position. If a stabilized flame burns on the flame arrester element surface, the melting element (3), located in a center position, will melt and let the spring Spring A spring is a spiral of wire which returns to its original shape after it is pressed or pulled. -loaded weather hood move into the open position. The PROTEGO® flame arrester unit consists of one or more FLAMEFILTER® (5), which are installed in a FLAMEFILTER® casing FLAMEFILTER® casing Enclosure for FLAMEFILTER® including insert rings. (4), a fixation element (6) and an insert ring (7).

For Explosion group IIB and IIA

The FLAMEFILTER® gap size, height, and quantity depend on the device’s intended use. The PROTEGO® EB series end-of-line deflagration flame arrester is available for substances from explosion Explosion Abrupt oxidation or decomposition reaction producing an increase in temperature, pressure, or in both simultaneously. group IIA and IIB (NEC group D and B). The standard design can be used with an operating temperature Operating temperature Temperature reached when the equipment is operating under design conditions. of up to +60°C / 140°F. Devices with special approval for higher temperatures are available upon request. EU conformity according to the currently valid ATEX directive. Approvals according to other national/international regulations on request.
