BE/HK

For many years the PROTEGO® BE/HK End-of-Line Deflagration Flame Arrester has been successfully used to protect 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 out-breathing and vent lines, with the goal to prevent flame transmission caused by endurance burning or atmospheric deflagration from propagating into the vessel or plant.

Detailing the operating conditions such as the temperature, explosion group and the composition of the fluid, enables PROTEGO® to select the best End-of-Line Deflagration Flame Arrester for your application. The PROTEGO® BE/HK Series End-of-Line Deflagration Flame Arrester is available for substances from explosion groups IIA to IIB3 (NEC groups D to C MESG ≥ 0.65 mm). In a modified design, this device is also available for Ethanol applications. The standard design can be used with operating temperature of up to +60°C / 140°F. Type-approved according to ATEX Directive as well as other international standards.
