20L explosion-proof filling machine

20L explosion-proof filling machine

Explosion-proof filling system for 20L drums with ATEX Zone 1 certification. Handles solvents/flammables (±0.1% accuracy). Grounding monitor & vapor recovery. 35 drums/hour.

  • Brand： glzon
  • Model： GZM_30L

Product Essence: Safety Engineered for Combustibles

Shanghai Guangzhi’s 20L Explosion-Proof Filler delivers ATEX/IECEx Zone 1 rated performance for acetone, ethanol, thinners (flash point <23°C). Featuring air-driven components, static-dissipative materials, and <0.1% filling accuracy, it achieves 35 drums/hour with vapor recovery >98% while maintaining oxygen concentration <5% LEL in hazardous environments.

Explosion-Proof Filler

Critical Safety Innovations

1. ATEX-Certified Architecture

ComponentEx-Proof Specifications
Pneumatic ActuatorsNo electrical sparks (ISO 80079-36)
Filling NozzlesERG-16 stainless steel (σ <10⁶ Ω)
Control CabinetIP65 purged enclosure (NEMA 4X)
SensorsIntrinsically safe IS barrier (Ex ia)

2. Flammable Vapor Management

  • Closed-Loop Vapor Recovery:

    • Activated carbon adsorption (95% efficiency)

    • Nitrogen blanketing (O₂ < 8% vol)

  • Static Control:

    • Double grounding verification (10⁴-10⁶ Ω resistance)

    • Conductive floor contact probes

3. Fire Mitigation

  • IR Flame Detectors: Triggers CO₂ deluge in <200ms

  • Pressure Relief Valves: 2.5 bar burst disks on tanks

  • Non-Sparking Conveyors: Ceramic bearings + bronze gears
