Function and Description

Eccentric Design

The PROTEGO® DA-E Series of Detonation Arresters are distinguished by its eccentric housing shape. When condensate accumulates within the PROTEGO® Flame Arrester Unit, the design allows the liquid to drain without collecting large amounts in the housing. The eccentric design of the device has distinctive advantages over the classic Flame Arresters when installed at lower depths.

Main Component – PROTEGO® Flame Arrester Unit

The detonation arrester is symmetrical and offers bi-directional flame arresting. The arrester essentially consists of two housing parts (1) and the PROTEGO® Flame Arrester Unit (2) in the center. The PROTEGO® Flame Arrester Unit consists of several FLAMEFILTER® discs (3) and spacers firmly held in a FLAMEFILTER® casing. The number of FLAMEFILTER® discs and their gap size depends on the arrester‘s intended use. By specifying the operating conditions, such as the temperature, pressure, explosion group, and the composition of the fluid, the optimum detonation arrester can be selected.

For Explosion Groups IIA to IIB3

The PROTEGO® DA-E Series of Flame Arresters are available for explosion groups IIA to IIB3 (NEC Group D to C MESG ≥ 0.65 mm). 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 higher temperatures are available upon request. Type-approved in accordance with the current ATEX Directive and EN ISO 16852, as well as other international standards.
