PROTEGO®
Deflagration Flame Arresters, end-of-line

Stop flame transmission at the vent before it reaches your tank
PROTEGO® End-of-line Deflagration Deflagration Explosion propagating at subsonic velocity (EN 1127-1:1997). Flame Arresters Flame arrester Device fitted to the opening of an enclosure, or to the connecting pipe work of a system of enclosures, and whose intended function is to allow flow but prevent the transmission of a flame. are 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. installed on vent lines of tanks, vessels, and plant 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. to prevent flame transmission caused by atmospheric deflagration, short-time burning, or endurance burning Endurance burning Stabilized burning for an unlimited time. .
Designed for the chemical, petrochemical, and pharmaceutical 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
Zero flashback incidents
Higher uptime & lower losses
Lifecycle confidence
Compliance made simpler
How It Works
When a flammable vapour cloud ignites at a vent outlet, the flame can propagate back into the
vessel

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.
Based on main process data, the different types of devices can
be selected from our product range:
- Atmospheric deflagration-proof, short time burning Short time burning Stabilized burning for a specific time. -proof, endurance burning-proof, or vent caps
- Explosion Explosion Abrupt oxidation or decomposition reaction producing an increase in temperature, pressure, or in both simultaneously. 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 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.
Key Features and Design Characteristics
- Gap size and configuration matched to explosion group
- Covers IIA to IIC
- Atmospheric Deflagration
- Short-time burning and
- Endurance burning protection
Deflagration and short time burning proof end-of-line Flame Arresters are equipped with a temperature sensor Temperature sensor 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.
- Replaceable FLAMEFILTER® elements
- Reduced maintenance Maintenance Combination of all technical and administrative actions, including supervision actions, intended to maintain or restore a unit in working order. time and cost
- Heating jackets or coils for condensation/freezing risks
- Electrical tracing as alternative
- Size and type of connection
- Approvals according to ATEX and other international standards
- Heating jacket or heating coil Heating coil A heating coil is a pipe connection consisting of several pipe sections.
