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 coating and as safety flame arrester element is unique throughout the world. The device 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 (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 (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 can be used for explosion group IIA (NEC group D). The standard design is approved at an operating temperature up to +60°C / 140°F and an absolute operating pressure acc. to table 3. EU conformity according to the currently valid ATEX directive. Approvals according to other national/international regulations on request.
