Detonation Flame Arrester

Detonation Flame Arrester


  • suitable for use in systems where detonation may occur – either unstable(during the transition of a combustion process from a deflagration into a stable detonation and where the explosion pressure is significantly higher than in a stable detonation) or stable (when it progresses through a confined system without significant variation of velocity and pressure characteristics),
  • prevents propagation of flames in flammable gas or vapour mixtures,
  • suitable for use in all explosion classes,
  • suitable for use in-line,
  • storage tanks with flammable liquids,
  • transport of flammable gasses, vapours and liquids,
  • chemical processing plants and oil refineries,
  • fuel, oil or biogas depots.



  • available design features include a one-way or two-way breather valve,
  • low pressure drop,
  • compact design,
  • designed, tested and certified to EN 12874 (ATEX) and Pressure Equipment Directive 97/23/EC (PED),
  • available in a range of materials offering different degrees of corrosion protection – for use in a variety of environments,
  • different connection options: flange or threaded,
  • available dimensions: DN15 – DN600 (depending on the design option and type of connection),
  • available with a heater and a wide range of additional accessories (temperature sensors, sight glass, pressure gauge, cleaning system).
