Function and Description

High-Tech Coating of the Housing

The PROTEGO® DR/ES-PTFE Series In-Line Detonation Flame Arresteris distinguished by its unique resistance to adhesive and corrosive media. The use of fluoroplastics as a high-tech housing Corps A housing is a solid shell, which surrounds a content, either protecting the content from external influences, or protecting the environment from the content. coating Revêtement Coating is the application of a firmly adhering layer of shapeless material to the surface of a workpiece. and as safety flame arrester element is unique throughout the world. The device Appareil 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. represents a further development of PROTEGO® Flame Arresters DR/ES in a right angle design that have been used and proven for decades in industry. The device protects against deflagrations and stable detonations.

Main Component – PROTEGO® Flame Arrester Unit (PTFE)

Once a detonation enters the Flame Arrester, energy is absorbed from the detonation shock wave by the integrated shock absorber Amortisseur de choc A shock absorber is a device that reduces the kinetic energy of a detonation. (1) before the flame is extinguished in the narrow channel of the PTFE FLAMEFILTER® (3). The PROTEGO® Flame Arrester Unit (2) consists of several FLAMEFILTER® discs and spacers firmly held in the FLAMEFILTER® cage Cage d'éléments arrête-flammes The FLAMEFILTER® cage is a housing for a FLAMEFILTER® set. (4). The gap size and number of FLAMEFILTER® discs are determined by the operating data parameters of the mixture flowing in the line (pressure, temperature).

For Explosion Group IIA

The detonation arrester Arrête-flammes antidétonation Flame arrester designed to prevent the transmission of a detonation. can be used for explosion group IIA (NEC group D). The standard design is approved at an operating temperature Operating temperature Temperature reached when the equipment is operating under design conditions. up to +60°C / 140°F and an absolute operating pressure Pression de service Operating pressure is the pressure existing at normal operating conditions within the system being protected. acc. to table 3. EU conformity according to the currently valid ATEX directive. Approvals according to other national/international regulations on request.
