PROTEGO®
Apagallamas a prueba de deflagraciones
Evitar una deflagración en una tubería
Los apagallamas a prueba de deflagraciones PROTEGO® se instalan en tuberías y en equipos de proceso y suprimen deflagraciones en sistemas que operan con mezclas explosivas
Están diseñados para instalarse en plantas químicas, petroquímicas, farmacéuticas y otras instalaciones industriales donde no se puede permitir que un frente de llama en una tubería llegue a los equipos ubicados aguas abajo.

Product Overview
Deflagration vs. Detonation
Flame Arrester Unit
Available Options
We are highly impressed to see the quality of the products and the knowledge to help us build a state-of-the-art storage terminal. We have always appreciated the timely deliveries of the flame arresters and other equipment.
Typical Applications for PROTEGO® Deflagration 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.
When a flame front enters the arrester, it passes through the FLAMEFILTER® discs. The narrow gaps create a large heat transfer surface, removing energy from the flame faster than combustion can be sustained. The flame is extinguished within the element.
How It Works
Element Design
The design of the element is not fixed. It is selected based on:
Key Features and Design Characteristics
The element can be removed and serviced without replacing the entire unit, reducing maintenance cost, effort and downtime.
Available in concentric, eccentric, and easy-access designs. Easy-access versions allow maintenance without disconnecting pipework- important in space-constrained or high-uptime environments.
Element gap size is optimized for the gas classification (MESG). Correct selection is critical to ensure effective flame arresting.
Options are available depending on whether flow direction is fixed or variable.
Designs are available for substances that may polymerise or crystallise, helping maintain long-term performance.
Heating jackets or coils can be added where condensation or solidification is a risk.
Where standard devices are not suitable, PROTEGO® can design and certify application-specific solutions.
For in-line installations, it is important to understand that protection is time-limited. If an ignitable mixture continues to flow after a flame is stopped, a fire can develop on the arrester itself. For this reason, systems must include:
- Temperature monitoring at the arrester
- A defined response, such as nitrogen purging
OEM-integrated Flame Arresters are tested and approved as part of the original equipment assembly and are not used as standalone devices.
Engineering and Compliance
PROTEGO® Deflagration Flame Arresters are type-tested and certified according to ATEX and other international standards. Each device is supplied with a statement of conformity defining its approved operating conditions.
Additional installation considerations include:
Sizing is based on the relationship between flow rate and pressure drop using the p/V performance diagram.
