1. Typical applicationsIt is suitable for quantitative filling of 200L foam free liquid in chemical, food and pharmaceutical industries.2. System OverviewGZM-200L explosion-proof liquid upper type liq
Zero Vapor ? Zero Static ? Absolute Safety
For Pyrophoric, Volatile & Oxygen-Sensitive Liquids (e.g., TDI, Acrylic Monomers, Silanes)
Shanghai Guangzhi Automation’s GZ-AquaLock Series revolutionizes hazardous liquid transfer by submerging 200L drums underwater during filling. This ATEX/IECEx-certified system eradicates ignition sources, suppresses 100% of VOC emissions, and achieves ±0.1% gravimetric accuracy – making it the ultimate solution for chemical plants handling EPA-listed Extremely Hazardous Substances (EHS).
? Vapor Suppression
Drum fills entirely underwater – no air contact = zero explosive atmosphere.
? Static Elimination
Water bath dissipates charge → prevents sparks (tested to <1 nJ MIE).
? Inerting Redundancy
Water layer + nitrogen blanket (optional) for pyrophorics (e.g., triethylborane).
? Spill Containment
Integrated water basin captures 200% drum volume (EPA SPCC-compliant).

Isocyanates (TDI/MDI): Prevents polymerization from moisture exposure.
Acrylic Monomers: Suppresses vapor while inhibiting runaway polymerization.
Silanes/Chlorosilanes: Neutralizes HCl formation via water hydrolysis.
Alkylmetals (e.g., TEAL): Dual water+N? barrier against pyrophoric ignition.
Oxygen-sensitive catalysts (e.g., Pd/C, Grignard reagents).
Peroxide-forming solvents (tetrahydrofuran, diisopropyl ether).
Pre-fill: Drum lowered into water basin → purged with N? (optional).
Submersion: Water fills basin → completely submerges drum.
Filling: Sealed filling lance penetrates drum lid → fills under water.
Post-fill: Lance retracts → basin drains → drum lifted.
Decontam: Auto-rinse cycle for drum exterior.
