Flameless relief
A flameless explosion venting device consists of a decompression panel and a special perforated steel enclosure. The protection system is mounted on the wall of the protected apparatus. When an explosion occurs inside, the decompression panel undergoes controlled “opening,” preventing a rise in pressure. Thanks to the use of the mentioned enclosure, the pressure is safely released into the environment. Importantly, this process does not involve the expulsion of a fireball, which is typical of traditional decompression panels. All of this ensures that this form of protection guarantees the highest level of safety, protecting both the device and the personnel, as well as other equipment that may be nearby. Unlike panels, flameless explosion venting can be used in enclosed spaces such as halls or buildings.
A special modification of the flameless explosion relief device is the EVN relief valve. It does not have a built-in decompression panel, so there is no need to replace it after an explosion. Instead, the valve consists of a spring that expands under the influence of the explosion and allows the pressure to escape, cooling the gases and extinguishing the flames in the process.

Alternative safety devices for large flameless explosion relief kits
Single-use protection method for indoor and outdoor use. Flames and pressure are NOT released into the environment. Reduced risk of fire in the apparatus after an explosion.
The most affordable protection method for use outside buildings. Flames and pressure are released into the environment (danger to people and equipment). The need to demarcate a danger zone.
Reusable protection device for indoor and outdoor use. Flames and pressure are NOT released into the environment. Minimal risk of fire in the apparatus after an explosion.
Security for coal and alternative fuels. For use outside buildings. Flames and pressure are released into the environment. Minimal risk of fire in the apparatus after an explosion
Are you looking for a system without the above restrictions?
Check the explosion suppression systems
If the above systems have too many limitations, and you are looking for the most advanced explosion protection system, then be sure to check out explosion suppression systems. This is the solution free of the restrictions listed above. Often, this is also a perfect solution in terms of price, especially when considering the longer term use and installation costs.

Explosion isolation
The isolation complements the explosion protection system mentioned above. The purpose of the explosion isolation is to isolate the device in which the explosion occurred from the rest of the system. This eliminates the risk of pressure and fire going over onto adjacent equipment, which would lead to very dangerous secondary explosions. Why is it so dangerous? Because the fire and pressure are characterised by much higher dynamics and energy, and there are no safeguards to protect us in such a situation.
Prevention
According to the ATEX Directive, the employer, in order to protect property and the health and life of workers, should implement measures to prevent and minimise the effects of an explosion. This approach is based on the fact that although the safeguards can significantly reduce the risk of explosion, they can never provide 100% safety. We are facing a similar approach in our cars. Despite a number of preventive measures such as the ABS system, every car has crash mitigation measures which include air bags, seatbelts or structural reinforcements.
