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

Función y Descripción

The PROTEGO® BE/HR -E-IIB end-of-line deflagration flame arrester was developed for vessels which are not pressurized. Main application area is on suction and vent lines, for sea going vessels but also useful for inland navigation vessels with the goal to prevent flame transmission caused by endurance burning or atmospheric deflagration 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.

The PROTEGO® BE/HR-E-IIB 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® cage. The PROTEGO® BE/HR-E-IIB end-of-line deflagration flame arrester is available for hydrocarbons for explosion group IIB (MESG ≥ 0,5 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.
