How It Works

When a flammable vapour cloud ignites at a vent outlet, the flame can propagate back into the vessel Behälter Container or structural envelope in which materials are processed, treated or stored. . End-of-line flame arresters Flame Arresters A flame arrester, deflagration arrester, or flame trap is a device or form of construction that will allow free passage of a gas or gaseous mixture but will interrupt or prevent the passage of flame. stop this flame at the vent opening.
At the core is the PROTEGO® FLAMEFILTER®, a precision-gapped disc system that quenches flames by dissipating heat faster than combustion can sustain.

The PROTEGO® devices are working to our utmost satisfaction. PROTEGO®—who, with their technical expertise, supported in reducing the overall life cycle cost of the Detonation Flame Arresters installed at our plant by installing flame arresters, which are easy to clean and maintenance-friendly.

Application Examples for PROTEGO® End-of-line Flame Arresters

  • Traitement par vapeur

  • Stockage basse-pression

  •  Stockage d'alcool

  • Sites chimiques et pharmaceutiques 

  • Énergies renouvelables

    We provide engineered safety solutions.

    Key Features and Design Characteristics

    • Atmospheric Deflagration 
    • Short-time burning and
    • Endurance burning protection 

    Deflagration and short time burning Kurzzeitiges Brennen Stabilized burning for a specific time. proof end-of-line Flame Arresters are equipped with a temperature sensor Temperatursensor Temperature sensor for monitoring the temperature. which detects a stabilized flame on the flame arrester element. If a flame is detected, measures have to be taken to extinguish the flame and prevent endurance burning.

    • Heating jackets or coils for condensation/freezing risks
    • Electrical tracing as alternative

    Operational Benefits
