Function and Description
Compact and Maintenance-Friendly Design
The PROTEGO® FA-CN In-Line
Deflagration Flame Arrester
Corta-chamas à prova de deflagracão
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 a compact design utilizing an easy access cover for easy
maintenance
Manutenção
Combination of all technical and administrative actions, including supervision actions, intended to maintain or restore a unit in working order.
. The special PROTEGO® FA-CN-IIC version was developed for hydrogen applications (group IIC vapors – NEC group B). The
device
Equipamento
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.
is designed with relatively large gap widths – related to IIC – which causes minimum pressure loss and allows for permeation of small liquid droplets or particles.
Main Component – PROTEGO® Flame Arrester Unit
The PROTEGO® Flame Arrester Unit can be removed and cleaned in just a few simple steps having to disassemble the pipe. When installing the Deflagration Flame Arrester, make sure that the distance between potential ignition sources and thelocation of the installed device does not exceed the L/D ratio (pipe length/ pipe diameter) for which the device was approved (see table 4). The Deflagration Flame Arrester is symmetrical and offers bidirectional flame transmission protection. The device consists of the
housing
Corpo
A housing is a solid shell, which surrounds a content, either protecting the content from external influences, or protecting the environment from the content.
(1) with an easy access cover (3) 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
