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.
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 al-low heat to dissipate to the environment.
The PROTEGO® EB-Z serie end-of-line deﬂagration ﬂame arrester is available for sub-stances of explosion group IIA (NEC group D MESG > 0.90 mm). The standard design can be used for operating temperatures up to +60°C / 140°F.
Type-approved according to ATEX Directive and EN ISO 16852 as well as other internationally accepted standards.
