Dust explosion suppression techniques

If you talk about using the most popular Explosion Protection System, explosion venting is the common name used in explosion protection strategy. If applied well, this venting protection will help avoid the explosion to reach its latent maximum pressures. This can be done by letting the expanding gases escape by using a planned passage. This way a lot of damage to industrial equipment through explosions can be controlled by using the explosion vents.

We also offer flameless explosion vents. These explosion vents are available with low-mass regulator plates and with low-pressure reactions. The flameless vents are prone to immediate reactions in case of an explosion within seconds. The flameless explosion vents instantly seal again after an explosion, thereby lowering the risk of a second explosion. Consequently, it also saves costly replacement charges.

Dust explosions can take place at any point during conveying or handling as well as during storage or any other stage when you use a huge pile of materials. Especially when using materials such as Charcoal, Aluminum, corn, grain, plastics, and other things that might explode under certain conditions. To avoid an explosion during such a condition, our Explosion Protection Systems provides dust collectors protection equipment.

Explosion Protection Systems contain components like Isolation Extinguisher, Vent Panel for Explosion Relief, Pressure Sensor, and Single Zone Control Panel, and so on.

The ATEX directive

The name ATEX comes from the French: “ATmosphères EXplosibles”. The applicable regulatory code in Europe is Directive 2014/34/EU (old designation 94/9/EC). This directive specifies that equipment and protective systems operated in potentially explosive atmospheres must be capable of dissipating electrostatic charge. Air filters used in these hazardous areas must also meet this requirement.

How should explosive atmosphere zones be divided?

Zone 0 / 20: Constant danger
The permanent presence of explosive gasses or combustive dust.

Zone 1 / 21: Potential danger
The occasional presence of explosive gasses or combustible dust during normal duty.

Zone 2 / 22: Minor danger
The presence of explosive gasses or combustible dust is not likely to occur or only for a shorter time.

Other countries with safety requirements

Teldust has access to various certification schemes, including ATEX, TR CU, USTC (US and Canada), MSHA, and IECEx, to trade globally.
