Function and Description

Main Component – PROTEGO® Flame Arrester Unit

The PROTEGO® BE/HK consists of a housing Corps A housing is a solid shell, which surrounds a content, either protecting the content from external influences, or protecting the environment from the content. (1), a weather hood Capot de protection contre les intempéries A weather hood is a cover to protect the internal components of a device from environmental influences. (2) and the PROTEGO® Flame Arrester Unit (3). During normal operation the metal weather hood is in a closed position. If a stabilized flame burns on the Flame Arrester Element surface, the fusible link (5), located in a center position, will melt and let the spring Ressort 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 two FLAMEFILTER® discs (4), which are installed in a FLAMEFILTER® casing FLAMEFILTER® casing Enclosure for FLAMEFILTER® including insert rings. . The FLAMEFILTER® gap size depends on the devices intended use.

For Explosion Groups IIA to IIB3

Detailing the operating conditions such as the temperature, explosion Explosion Abrupt oxidation or decomposition reaction producing an increase in temperature, pressure, or in both simultaneously. 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/HK 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 Operating temperature Temperature reached when the equipment is operating under design conditions. of up to +60°C / 140°F. Type-approved according to ATEX Directive as well as other international standards.
