Função e descrição
Protection Against Atmospheric Deflagration and Endurance Burning
The PROTEGO® EB-Z End-of-Line Deflagration Flame Arrester has been successfully used to protect small vessels and process engineering apparatus which are not pressurized. The device provides protection against flame transmission through atmospheric deflagration and stabilized flames which can burn for very long time on the flame arrester element surface, so called endurance burning. Main application area is on in- and outbreathing vent lines, with the goal to prevent flame transmission caused by endurance burning or atmospheric deflagration from propagating into the vessel or plant.
Main Component – PROTEGO® Flame Arrester Unit
The PROTEGO® EB-Z consists of a housing (1), a weather hood (2) and the FLAMEFILTER® (3). The weather hood is made out of acrylic glass, which will melt when impacted by flames and allow heat to dissipate to the environment. The PROTEGO® EB-Z Series End-of-Line Deflagration Flame Arrester is available for substances of explosion group IIA (NEC group D MESG > 0.90 mm)
Many Individual Certifications
The standard design can be used for operating temperatures up to +60°C / 140°F. EU conformity according to the currently valid ATEX directive. Approvals according to other national/international regulations on request.
