BE/HK-E-IIB3

Deflagration Flame Arrester, endurance burning proof, End-of-Line

Função e descrição

The PROTEGO® BE/HK-E-IIB3 end-of-line deflagration flame arrester was specifically developed for vessels which are not pressurized and store Ethanol or other alcohols. The combustion of alcohol requires a modified flame arrester element design to provide protection against endurance burning. In addition, the device provides protection against atmospheric deflagration. Main application area is on suction and vent lines, for Inland navigation vessels and on shore systems with the goal to prevent flame transmission caused by endurance burning or atmospheric deflagration.

The PROTEGO® BE/HK-E-IIB3 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 stabilized 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® cage.

The PROTEGO® BE/HK-E end-of-line deflagration flame arrester is available for hydrocarbons for explosion group IIB3 (MESG ≥ 0,65 mm) and alcohols.

The standard design can be used for operating temperatures up to +60°C / 140°F.

Type-approved in accordance with ATEX Directive and EN ISO 16852 as well as other international standards. Approved according to IMO MSC/Circular 677 and 1009 as well as IMO MSC.1/Circular 1324 and 1325.
