Function and Description

Bidirectional flame transmission protection

When installing the deflagration Deflagration Explosion propagating at subsonic velocity (EN 1127-1:1997). flame arrester make sure that the distance between potential ignition sources and the location of the installed 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. , the L/D ratio (pipe length/pipe diameter), does not exceed the value of 50. The deflagration flame arrester is symmetrical and offers bidirectional flame transmission protection.

Main component - PROTEGO® flame arrester

The arrester essentially consists of two coated housing parts (1) and the PROTEGO® flame arrester unit PROTEGO® flame arrester unit The PROTEGO® flame arrester unit is the main component of a flame arrester. It prevents flame propagation. (2) in the center. The PROTEGO® flame arrester unit is modular and consists of several FLAMEFILTER® discs (3) and spacers firmly held in a FLAMEFILTER® casing FLAMEFILTER® casing Enclosure for FLAMEFILTER® including insert rings. . The number of PTFE-FLAMEFILTER® discs and their gap size depends on the arrester‘s conditions of use.

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”.
