Function and Description

Protects Against Deflagrations and Stable and Unstable Detonations

The PROTEGO® DR/EU series of in-line detonation flame arresters represents further development of PROTEGO® Flame Arrester Series DR/ES, which has been successfully used in industry for decades. The device protects against deflagrations and stable and unstable detonations. The classic right-angle design offers considerable costs and maintenance advantages over the straight-through design.

Main Component – PROTEGO® Flame Arrester Unit

Once a detonation enters the Flame Arrester, energy is absorbed from the detonation shock wave by the integrated shock absorber (1) before the flame is extinguished in the narrow gaps of the FLAMEFILTER® (3). The PROTEGO® Flame Arrester Unit (2) consists of several FLAMEFILTER® discs and spacers firmly held in the FLAMEFILTER® casing (4). The gap size and number of FLAMEFILTER® discs are by the operating conditions of the flowing mixture (explosion group, pressure, temperature). This device is can be used for explosion groups from IIA to IIB3 (NEC group D to C MESG ≥ 0.65 mm).

Many Individual Certifications

The standard design can be used with an operating temperature of up to +60°C / 140°F and an absolute operating pressure acc. to table 3. Devices with special approval for higher pressures and temperatures are available upon request. EU conformity according to the currently valid ATEX directive. Approvals according to other national/international regulations on request.
