【Explosion Protection Challenges】
Combustible dust is commonly generated in industrial processes such as metalworking, grinding, chemical processing and lithium battery production. When dispersed in the air at a sufficient concentration and exposed to an ignition source—including sparks, electrostatic discharge, or hot surfaces—it can result in a devastating dust explosion.
As dust collectors continuously capture and accumulate combustible dust, they represent one of the highest-risk areas within a production system. Effective explosion protection is therefore critical—not only to protect the dust collection equipment itself, but also to safeguard personnel, production facilities, and the entire manufacturing process.
【CHIKO's Solutions】
Effective explosion protection measures should address three key aspects: prevention of ignition sources, reduction of explosion risks, and limitation of explosion consequences.
CHIKO explosion-proof dust collectors incorporate the following policies:
| Prevention Target |
Risk Factors | Policy |
| Ignition sources | Non-explosion-proof control panels may become potential ignition sources | 1. Explosion-proof control panel design 2. Reduced ignition risk 3. Products certified according to IECEx |
| Static electricity / Weak machine structure | Static discharge may trigger dust explosions, insufficient enclosure strength may cause damage or flying fragments | 1. Use conductive filter media 2. Enhanced sealing of enclosure joints 3. Reliable grounding inside the enclosure 4. Products designed in compliance with ATEX |
| Explosion | Internal pressure caused by explosion may damage equipment | Bursting panel, explosion relief vent |
| Fire | Flame propagation may spread and cause damage to surrounding areas | Flameless explosion vent |
【Safety Backed by International Explosion Protection Standards】
CHIKO's Explosion Protection Series is designed in accordance with internationally recognized explosion protection standards. The products are IECEx certified and compliant with the European ATEX Directive. Notably, they are the first dust collectors in Japan to obtain IECEx certification.
Communication and control equipment are among the components most susceptible to generating ignition sources through electrostatic discharge, making them a critical factor in dust explosion prevention. By incorporating IECEx-certified communication and control systems, which are also used in ATEX-compliant models, CHIKO provides an even higher level of safety assurance backed by internationally recognized certification.
Furthermore, ATEX is the mandatory explosion protection standard in Europe. Compliance with ATEX demonstrates that the equipment is designed and constructed to meet internationally recognized explosion safety requirements.
