25L Canister Filling Machine
Sealed Precision ∙ Zero Vapor Leak ∙ ±0.15% Accuracy
For Hazardous Chemicals, Solvents & Oxygen-Sensitive Liquids
Shanghai Guangzhi Automation’s GZ-C25 Series redefines canister filling with hermetic sealing technology, ATEX Zone 1 compliance, and laboratory-grade gravimetric accuracy (±0.15%). Engineered for UN-certified 25L canisters, this system eliminates vapor emissions, prevents cross-contamination, and fills 28 canisters/hour – ideal for pyrophoric chemicals, high-purity solvents, and pharmaceutical intermediates.

Core Innovations
✅ Hermetic Sealing System
Double O-ring lance + nitrogen purge creates oxygen-free environment (<10 ppm O₂).
✅ Explosion-Proof Architecture
ATEX Ex db IIC T6 (Zone 1) for solvents with flash point <23°C.
✅ Static-Safe Transfer
Conductive PTFE lances (10⁵ Ω) + auto-grounding verification (<5 Ω).
✅ Quick-Change Adaptors
Tool-free swap for DIN/ISO/BS canister threads in <45 seconds.
✅ Moisture Control
-70°C dew point N₂ blanket prevents hydrolysis.
