SF6 Recovery Separation Purification Device – 99.99% Distillation, Filtration, Air-Cooled, KSLF-30WY20/63/100/N
System Overview
This three-in-one device integrates recovery, separation, and purification functions to process SF6 gas contaminated with air, moisture, or decomposition products. Through liquid-solid phase processing, it efficiently discharges N₂, O₂, and other impurities via distillation purification, achieving 99.99% SF6 concentration post-treatment.
Technical Features
- Integrated Filtration System: Adsorbs moisture, particles, decomposition byproducts, and oil residues
- Compact All-in-One Design: Portable structure for easy on-site deployment
- Maintenance-Free Filtration: Self-cleaning mechanism ensures consistent gas quality
- Phase Sequence Protection: Prevents motor reversal via built-in protective circuitry
- Air-Cooled Operation: Eliminates need for external water supply (ideal for field use)
- Extreme Temperature Performance: -20°C to +60°C operational range with thermal protection
- Regenerative Desiccant System: Heated activation eliminates replacement needs
- Auto-Compensating Valves: Ball valves with self-sealing performance for zero leakage
- Vacuum Power Protection: Prevents oil backflow during power outages
