Function and Description

Protection of Ethanol and Alcohols in Non-Pressurized Systems and Containers

The PROTEGO® BE/HK-E end-of-line deflagration Deflagration Explosion propagating at subsonic velocity (EN 1127-1:1997). 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 Endurance burning Stabilized burning for an unlimited time. . In addition, the device Device A device is a pipe component that influences the media flow by opening, closing, or partially shutting off the flow channel or by dividing or mixing the media flow. provides protection against atmospheric deflagration. It is typically installed on in-breathing and out-breathing vent lines to prevent flame transmission into the vessel Vessel Container or structural envelope in which materials are processed, treated or stored. or plant caused by endurance burning or atmospheric deflagration.

Main component - PROTEGO® flame arrester

The PROTEGO® BE/HK-E consists of the housing Housing 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 (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 melting element (5), located in a center position, will melt, and the spring Spring A spring is a spiral of wire which returns to its original shape after it is pressed or pulled. -loaded weather hood will open. 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. .

For Explosion group IIB1

The PROTEGO® BE/HK-E end-of-line deflagration flame arrester is available for alcohols and other substances with MESG ≥ 0,85mm. 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.

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”.
