KSLF-30WY20/63/100/N

System Overview

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

1. Recovery Stage: Compressed SF6 gas intake via oil-free pump
2. Separation Stage: Distillation removes N₂/O₂ through temperature gradient control
3. Purification Stage:
   • Particulate filtration (0.1μm)
   • Moisture adsorption (molecular sieve)
   • Decomposition product removal (chemical adsorption)
