QTHS-1-15
15m³/h SF6 Gas Recovery, Filtration, and Refilling System
The SF6 Gas Recovery, Filtration & Refilling Equipment is developed for safe and efficient handling of sulfur hexafluoride (SF6) gas used in gas-insulated electrical equipment. The system integrates evacuation, gas recovery, filtration, storage, and refilling functions into a single service unit for maintenance and operational support.
Recovered SF6 gas is filtered to remove moisture and solid contaminants before being stored or refilled into electrical apparatus. The equipment ensures controlled gas handling while reducing gas loss during maintenance activities.
Designed with a compact structure and mobile configuration, the unit is suitable for both substation field service and workshop applications, supporting reliable and standardized SF6 gas management.
High-Efficiency 15m³/h SF6 Gas Recovery, Filtration, and Refilling System is a fully integrated gas handling solution, combining recovery, vacuum-assisted filtration, and precise refilling functions. The system ensures safe operation, accurate measurement, and effective removal of impurities under various service conditions. Optional industrial computer and remote control configurations provide flexible operation and process monitoring for substations, workshops, and field applications.
At YUNENG, we understand that different substations require different handling speeds. Our SF6 recovery systems are available in multiple capacities, ranging from compact 2m³/h units for distribution switchgear to high-capacity 10m³/h, 15m³/h, 30m³/h or larger compressor models for large-scale GIS projects. Whether you prioritize extreme portability or rapid recovery speed, we have the right configuration to optimize your maintenance workflow.
