PROTEGO®
Flame Arresters
Reliable Explosion Protection
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. Pressure/vacuum relief valve Pressure/vacuum relief valve is an umbrella term that includes pressure or vacuum relief valve as well as pressure and vacuum relief valve. are essential safety devices designed to prevent the spread of flames in pipelines, tanks, and process equipment Equipment Machines, appliances, fixed or mobile devices, control parts and accessories, and warning and prevention systems, whether separate or combined, intended for the generation, transfer, storage, measurement, control, and conversion of energy, and for the processing of materials, which have their own potential source of ignition and may cause an explosion. .
By stopping the propagation of explosions and flashbacks, they protect people, assets, and operations in demanding industrial environments. A Flame Arrester allows the safe passage of gases and vapors while reliably preventing flame transmission. It consists of spirally wound metal bands that create precisely defined flame‑ quenching Quenching Cooling of a fluid by mixing it with another fluid of a lower temperature. gaps. These gaps are engineered to match the ignition and transmission characteristics of explosive vapors, ensuring effective protection under real operating conditions.

Working principle of Flame Arresters
The FLAMEFILTER® is made of wound metal strips and forms an effective band arrester. This flame-quenching principle is applied in PROTEGO® end-of-line Flame Arresters and in-line Flame Arresters.
When a mixture ignites in a gap, the flame spreads towards the unburned mixture. The volume expansion of the burned mixture pre-compresses the unburned mixture and accelerates the flame propagation.
Heat dissipation to the large surface of the gap lowers the temperature below the ignition temperature Ignition temperature Lowest temperature (of a hot surface) at which ignition of a flammable gas or vapor in a mixture with air or air/inert gas occurs under specified test conditions. , thus extinguishing the flame.
The gap width and gap length determine the extinguishing effectiveness of the Flame Arrester.
A narrower and longer gap extinguishes the flame more effectively, while a wider and shorter gap reduces the pressure loss. Experiments can determine the optimum solution between the two conditions.
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.
We provide engineered safety solutions.
Since 1954, PROTEGO® has built and provided Flame Arresters, Pressure and Vacuum Vacuum Vacuum is the pressure in an enclosed space that is lower than the ambient pressure. Relief Valves and Tank Equipment, now with the help of more than 750 employees worldwide.
