Description
GSH-C-YNA-11/45 is a compact cost-effective SF₆ gas handling machine designed for power distribution teams, switchgear after-sales service, industrial enterprises and third-party testing institutions. It is dedicated to SF₆ gas recovery, vacuumizing, purification, liquefied storage and pressure-regulated refilling during installation, routine maintenance and decommissioning of 10kV ~ 110kV SF₆ circuit breakers, ring main units, instrument transformers and small-capacity GIS compartments.
It adopts an oil-free SF₆ dedicated compressor and a two-stage rotary vane vacuum pump, delivering 11m³/h recovery rate and 45m³/h vacuum pumping speed. The built-in 300L liquefied storage tank with pressure vessel certification eliminates the need for external gas cylinders and improves on-site operation convenience. The multi-stage deep purification system effectively removes moisture, decomposition products, oil residues and dust particles, ensuring recovered gas meets IEC 60480 reuse standards.
