FLEX - FLAMELESS EXPLOSION VENTING

The FLEX flameless explosion venting device is a suitable solution for installation on technological equipment inside buildings or in production halls. Unlike conventional explosion venting, where temperatures up to 1 500 °C can be achieved, the FLEX device can cool the flame and flue gas temperatures to a level that is no longer dangerous for technology and the people around the equipment. FLEX meets the strictest requirements of the legislation for flameless venting and is certified according to EN 16009.

WHERE IS THE RISK?

In environments where combustible dust, such as metal or melt dust, is present, the potential for explosion poses a significant risk. Conventional explosion venting methods, especially when utilized indoors or in close proximity to other equipment outdoors, can pose serious hazards to workers, their well-being, and the surrounding production infrastructure.

and other industrial equipment

FLEX MAINTAINS TWO FUNCTIONS

Explosion venting and prevention of fire propagation into free space are two basic functions of the device.

The explosion venting device opens due to fast increasing pressure and the FLEX absorbs flame, burning dust, and gases. As opposed to an explosion venting the FLEX device is capable to absorb these undesirable effects thanks to its construction.

The explosion venting can achieve temperatures up to 1 500 °C, with light metals such as aluminum and magnesium the temperature being around 3 000 °C. During explosion venting with the FLEX flameless equipment, the temperature is lowered to a safe level that is not dangerous for surrounding equipment and for work and movement of personnel.
