QTHS-1-10
10m³/h SF6 Gas Recovery and Filling Unit
The YUNENG SF6 Gas Recovery System is a high-efficiency mobile unit designed for the fundamental management of Sulfur Hexafluoride gas in power high-voltage equipment.
This system provides a streamlined solution for evacuation, recovery, high-precision filtration, and controlled refilling. It is specifically engineered to recover SF6 gas from GIS and circuit breakers, passing it through a multi-stage physical filtration system to remove mechanical impurities, dust, and residual moisture. By ensuring the gas is clean and dry before storage or refilling, this unit protects the internal insulation of your electrical assets and extends their service life.
It is the ideal choice for routine maintenance where gas purity remains stable but physical debris and moisture need to be managed.
The QTHS-1-10 system is designed with modular units for vacuum-assisted recovery, filtration, and refilling, adaptable to different SF6 volumes and operational requirements.
