Deflagration Flame Arrester, endurance burning proof, End-of-Line
Features
Function and Description
Protection Against Atmospheric Deflagration and Endurance Burning
The PROTEGO® BE/HR-E End-of-Line Deflagration Flame Arrester has been specifically designed for the protection of non-pressurized systems and containers. The device is preferably installed on venting and breathing lines of non-pressurized systems and containers as well as on sea and inland tank vessels and thus prevents the entry of fire or atmospheric deflagration. The specific process of combustion reactions during stabilized burning of alcohols necessitates a constructively adapted flame arrester. The equipment provides safety against atmospheric deflagrations and endurance burning
Main Component – PROTEGO® Flame Arrester Unit
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® casing.
For Explosion Group IIB
The PROTEGO® BE/HR-E 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. EU conformity according to the currently valid ATEX directive. Approvals according to other national/international regulations on request. Approved according to IMO MSC/Circular 677 as well as IMO MSC.1/Circular 1324 and 1325.

Flow Capacity Chart
The flow capacity charts have been determined with a calibrated and TÜV certified flow capacity test rig. Volume flow V in (m³/h) and CFH refer to the standard reference conditions of air ISO 6358 (20°C, 1bar). For conversion to other densities and temperatures refer to Sec. 1: “Technical Fundamentals”.
