Function and Description

Excentric Design

The PROTEGO® FA-E-IIA1 series of in-line deflagration flame arresters Deflagration flame arrester Flame arrester designed to prevent the transmission of a deflagration. It can be an end-of-line flame arrester or an in-line flame arrester. is designed with an eccentric housing Housing A housing is a solid shell, which surrounds a content, either protecting the content from external influences, or protecting the environment from the content. to automatically drain condensate build up in the housing. The PROTEGO® FA-E-IIA1 in-line flame arrester In-line flame arrester An in-line flame arrester is a flame arrester, which has pipe connectors on either side of the flame arrester unit. was specially developed for bio-, sewage- and landfill-gas applications. The application as an endurance burning Endurance burning Stabilized burning for an unlimited time. proof in-line device Device 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. under atmospheric conditions Atmospheric conditions Atmospheric conditions are pressures from 80 kPa till 110 kPa and temperatures from -20°C up to +60°C. without extensive temperature monitoring is of advantage.

For Explosion group IIA1

Due to its eccentric design and in contrast to conventional concentric flame arresters Flame Arresters A flame arrester, deflagration arrester, or flame trap is a device or form of construction that will allow free passage of a gas or gaseous mixture but will interrupt or prevent the passage of flame. the device can be installed in pipelines that run close to floors or walls. When installing the deflagration Deflagration Explosion propagating at subsonic velocity (EN 1127-1:1997). flame arrester make sure that the distance between potential ignition sources and the location of the installed device does not exceed the L/D ratio (pipe length/pipe diameter) for which the device was approved. According to EN ISO 16852 the installation limits are (L/D)max ≤ 50 for deflagration flame arresters for explosion group IIA1- methane (former designation Expl.gr. I).

Main component - PROTEGO® flame arrester

The deflagration flame arrester is symmetric and offers bidirectional flame transmission protection. The arrester essentially consists of two housing parts (1) and the PROTEGO® flame arrester unit PROTEGO® flame arrester unit The PROTEGO® flame arrester unit is the main component of a flame arrester. It prevents flame propagation. (2) in the center. The PROTEGO® flame arrester unit is modular and consist of several FLAMEFILTER® (3) and spacers firmly held in a FLAMEFILTER® casing FLAMEFILTER® casing Enclosure for FLAMEFILTER® including insert rings. .

Many Individual Certifications

The PROTEGO® FA-E-IIA1 flame arrester protects against deflagrations and endurance burning (under atmospheric condition up to DN 200 / 8”) of explosion group IIA1 - methane (former designation Expl.gr. I). The PROTEGO® FA-E devices for substances of explosion groups IIA, IIB3 and IIC (NEC groups B, C, and D) are shown on separate pages. The standard design can be used up to an operating temperature Operating temperature Temperature reached when the equipment is operating under design conditions. of +60°C / 140°F and up to an absolute operating pressure Operating pressure Operating pressure is the pressure existing at normal operating conditions within the system being protected. of 1.1 bar / 15.9 psi. Numerous devices with special approvals can be obtained for higher temperatures and pressures. EU conformity according to the currently valid ATEX directive. Approvals according to other national/international regulations on request.
