Protection Against Atmospheric Deflagration and Endurance Burning
The PROTEGO® EB End-of-Line Deflagration Flame Arrester provides protection against atmospheric deflagration and long-lasting stabilized flames, called endurance burning. The device is typically installed on vent lines of vessels and plant equipment which is not pressurized. The device prevents flame transmission from endurance burning or atmospheric deflagration into the vessel or plant.
Main Component – PROTEGO® Flame Arrester Unit
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-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 (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 group IIA and IIB (NEC group D and B). The standard design can be used with an operating temperature 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.
