LH/EB Deflagration Flame Arrester

Brand: PROTEGO
Request Information
The Protego LH/EB end-of-line deflagration flame arrester is used to protect process engineering apparatus and vessels which are not pressurized and process Methane/Air mixtures. 

The device provides protection against flame transmission through atmospheric deflagration and stabilized flames which can burn for a very long time. 

This device is specifically applied to vent lines of decommissioned underground mines. 

Other areas of application are biogas, land-fill gas and sewage gas. 

The device is installed on suction and vent lines, with the goal to prevent flame transmission caused by endurance burning or atmospheric deflagration propagating into the vessel or plant.
Features
  • Most efficient deflagration flame arrester for methane/air mixtures
  • Certificates for mining are available
  • Protection against atmospheric deflagration and endurance burning
  • Weather hood protects against environmental impact (i.e. Weather, bird nests, etc.)
  • Weather hood will open and signals the impact of a flame
  • Fusible link is resistant against chemicals
  • Maintenance friendly design
