Equipment Description:

1. Explosion-proof design standards
ATEX 2014/34/EU certification | Dust explosion-proof level: DIP A21 T135℃ | Pressure relief area ratio ≥0.05m²/m³
2. Special design features
1. ‌Static dissipation system‌:
▸ Conductive floor (resistance value 10⁴-10⁶Ω)
▸ Ion wind bar (balance voltage <±50V)
2. ‌Fire extinguishing and explosion suppression device‌:
▸ High-pressure fine water mist system (10μm droplet size)
▸ Chemical explosion suppression agent storage tank (5kg dry powder storage)
It is recommended to conduct air tightness testing (pressure decay method) and ground resistance testing (<10Ω) regularly. When operating in a flammable environment, the internal pressure of the equipment must be kept in a negative state (-50Pa to -100Pa).
3. Typical application scenarios
‌Automobile manufacturing industry‌: New energy battery shell spraying
‌Electronic equipment‌: Server cabinet surface treatment
‌Military industry‌: Anti-corrosion coating for ammunition storage boxes
