  • Product Details
  • Operating Principle:

    The unstable detonation flame arrester incorporates advanced flame arresting elements, developed through extensive research and testing. These elements form a robust layered unit capable of withstanding high kinetic energy loads and managing increased pressure drops. The device effectively prevents flame and shock wave penetration during deflagration or detonation events.

    Applications::

    • Chemical processing devices and petroleum refining plants
    • Oil and gas storage facilities at terminals
    • Biogas treatment facilities at wastewater plants
    • Waste incineration plants
    • Large tank areas for chemical raw materials
