Function and Description

In-Line Detonation Flame Arresters with Shock Wave Guide Tube Effect

The In-Line Type PROTEGO® DA-SB-EO are the newest generation of Flame Arresters. Based on flow and dynamic calculations as well as decades of field tests, a line was developed that offers minimum pressure losses with maximum safety. The Flame Arrester uses the Shock Wave Guide Tube Effect (SWGTE) to separate the flame front and shock wave. The result is an in-line without a classic , which minimizes the use of FLAMEFILTER® discs.

Main Component – PROTEGO® Flame Arrester Unit

The devices are symmetrical and offer bi-directional flame arresting for deflagrations and stable detonations for Ethylene oxide/air-mixtures. The arrester essentially consists of two parts with an integrated shock tube (1) and the PROTEGO® Flame Arrester Unit (2) in the center. The PROTEGO® Flame Arrester Unit is modular and consists of several FLAMEFILTER® discs (3) and spacers firmly held in a .

Many Individual Certifications

The standard design can be used with an of up to +60°C / 140°F and an absolute up to 1.1 bar / 15.9 psi. EU conformity according to the currently valid ATEX directive.
