LH/AD Deflagration Flame Arrester, End-of-Line

The PROTEGO® LH/AD end-of-line deflagration flame arrester provides protection against flame transmission through atmospheric deflagration. The device is typically installed on vent lines of vessels and plant equipment which are not pressurized. For safe application, it is important that an endurance burning situation can be excluded. So typically, it is installed on vent lines which discharge vapor for a short time period. The device prevents flame transmission from atmospheric deflagration into the vessel or plant. These devices must be selected and installed based on: The gas/vapor explosion group (IIA, IIB, IIC, etc.) Operating conditions (temperature, flow rates) Compliance with relevant ISO, EN, ATEX, UL, and local regulatory requirements.
