Dust Collectors for Combustible Dust

Dust Collectors Handling Explosive Atmospheres (ATEX)

Dust explosions pose significant risks at various stages of material processing, such as conveying, storage, and any phase where large accumulations of materials occur. Materials like charcoal, aluminum, corn, grains, and plastics are particularly prone to explosions under specific conditions. Therefore, the risk of explosion must be carefully considered when designing extraction and filtration systems.

Due to their design and lack of moving parts, Teldust dust collectors fall outside the scope of the ATEX directive. Nevertheless, they are fully capable of handling explosive atmospheres, such as ATEX zones 20, 21, and 22 internally.

When a dust collector is tasked with handling combustible dust, Teldust offers a variety of solutions designed to protect the filter body against explosions. Our most commonly applied protection method is explosion venting panels on the filter body, although we also provide options for explosion suppression and flameless explosion venting. These tailored solutions help contractors and system installers deliver safe, compliant filtration systems to their clients.

Dust Collectors with Explosion Venting Panels

Explosion venting is a widely recognized method for explosion protection. When handling explosive atmospheres and combustible dust, dust collectors are often equipped with explosion venting panels.

Properly installed, these panels serve as a critical defense against uncontrolled explosions. By directing explosion pressure through a predetermined pathway, venting panels help maintain the structural integrity of the dust collector body, reducing damage to the equipment and ensuring safety for the surrounding area.

Dust Collectors with Flameless Explosion Venting

For installations requiring additional safety measures, Teldust offers flameless explosion venting solutions. This advanced technology contains the flame effects produced during an explosion, offering protection for people and property within enclosed spaces. Unlike traditional venting panels, flameless venting effectively neutralizes flames without releasing them into the surrounding area, providing optimal protection for indoor environments.

Dust Collectors with Explosion Suppression

To safeguard operations in high-risk environments, Teldust also offers explosion suppression technology for dust collectors. This proactive safety measure detects the initial combustion of an explosive atmosphere and introduces extinguishing powder to suppress the explosion within milliseconds, preventing destructive pressure buildup and mitigating the risk of extensive damage.
