Drum Filling Machine Explosion proof1. Typical applicationsIt is suitable for quantitative filling of 200L foam free liquid in chemical, food and pharmaceutical industries.2. System OverviewGZM-200L e
ATEX/IECEx Certified ∙ ±0.15% Accuracy ∙ 100% Ignition Risk Elimination
*For Flammable Solvents, Chemicals & Volatile Liquids (Zone 1/21)*
Shanghai Guangzhi Automation’s GZ-ExDrum Series sets the industry benchmark for safe and precise filling of 200L drums with hazardous liquids. Engineered with triple-redundant explosion protection, this ATEX/IECEx-compliant system eradicates ignition sources, captures 99.9% VOC emissions, and delivers ROI in <12 months through zero material loss and labor reduction.
✅ Pressurized Control Cabinets
Ex pxb IIC T4/T6 rated – maintains positive pressure to exclude explosive gases.
✅ Intrinsically Safe Sensors
Ex ia IIC T6 circuits (<1mA energy) for level, flow, and vapor detection.
✅ Static Dissipation System
Conductive fill lances (10⁵ Ω) + auto-grounding verification (<10 Ω resistance).
✅ Double-Sealed Motors
Ex db IIB+H2 T4 rated pumps with leak detection.
✅ Emergency Inerting
Nitrogen purge activates if O₂ >5% or VOC >25% LEL.
