???

recommendation index：

Intelligent design, simple and convenient operation

Recovery and Rapid Separation of SF6/N2 Mixed Gas

Automatic recognition of cylinder status and automatic stop of filling

Large flow rate high precision mass flow controller

Device for rapid recovery, purification, separation and filling of sulfur hexafluoride mixed gas
It is mainly composed of gas circuit system, vacuum system, evaporation and gasification system, gas pretreatment system, gas recovery and separation system, refrigeration liquefaction model system, exhaust gas treatment system, SF₆ gas filling system, dynamic gas distribution system, pressurized gas charging system, gas detection system, gas storage tank and intelligent control system
Membrane separation technology or cryogenic solidification separation technology is used to separate the SF₆ mixed gas, and the N₂ gas is discharged into the atmosphere in a high-purity state after being cycled and infiltrated
