PROTEGO®
Deflagration Flame Arresters, end-of-line
Stop flame transmission at the vent before it reaches your tank
PROTEGO® End-of-line Deflagration Flame Arresters are installed on vent lines of tanks, vessels, and plant equipment to prevent flame transmission caused by atmospheric deflagration, short-time burning, or endurance burning.
Designed for the up and downstream oil and gas, petroleum, chemical, pharmaceutical, offshore, marine and bio-energy industries, the range covers a wide variety of types, designs, sizes, and materials, with customized solutions for non-standard substances and applications.
Highlights of PROTEGO® End-of-line Flame Arresters
How It Works
When a flammable vapour cloud ignites at a vent outlet, the flame can propagate back into the vessel. End-of-line flame arresters 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.
Based on main process data, the different types of devices can
be selected from our product range:
- Atmospheric deflagration-proof, short time burning-proof, endurance burning-proof, or vent caps
- Explosion Explosion Plötzliche Oxidations- oder Zerfallsreaktion mit Anstieg der Temperatur, des Druckes oder beider gleichzeitig. group of the processed mixture
- Standard or special operating conditions with higher temperatures
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
We provide engineered safety solutions.
Since 1954, PROTEGO® has built and provided Flame Arresters, Pressure and Vacuum Relief Valves and Tank Equipment, now with the help of more than 750 employees worldwide.
Key Features and Design Characteristics
- Gap size and configuration optimized to the explosion group
- Covers IIA to IIC
- Atmospheric Deflagration
- Short-time burning
- Endurance burning
Deflagration and short time burning proof end-of-line Flame Arresters are equipped with a temperature sensor 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 in accordance to international standards.
