Function and Description

Protection Against Atmospheric Deflagration and Endurance Burning
For many years the PROTEGO® BE/HR End-of-Line Deflagration Flame Arrester has been successfully used to protect vessels and process engineering apparatus which are not pressurized. The device provides protection against flame transmission through atmospheric deflagration and stabilized flames which can burn for very long time on the Flame Arrester Element surface, so called endurance burning. Main application area is on in- and out-breathing and vent lines, with the goal to prevent flame transmission caused by endurance burning or atmospheric deflagration from propagating into the vessel or plant.

Main Component – PROTEGO® Flame Arrester Unit
The PROTEGO® BE/HR consists of a housing (1), a weather hood (2) and the PROTEGO® Flame Arrester Unit (3). During normal operation the metal weather hood is in a closed position. If a flame burns on the Flame Arrester Element surface, the fusible link (5), 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 two FLAMEFILTER® discs (4), which are installed in a FLAMEFILTER® casing.

For Explosion Groups IIA to IIB3
The FLAMEFILTER® gap size will depend on the devices intended use. Detailing the operating conditions such as the temperature, explosion group and the composition of the fluid, enables PROTEGO® to select the best End-of-Line Deflagration Flame Arrester for your application. The PROTEGO® BE/HR Series End-of-Line Deflagration Flame Arrester is available for substances from explosion groups IIA to IIB3 (NEC groups D to C MESG ≥ 0.65 mm). In a modified design, this device is also available for Ethanol applications.
The standard design can be used with operating temperature of up to +60°C / 140°F.
Type-approved according to ATEX Directive as well as other international standards.
