▎Product Introduction ：
RF-151M Mixed Insulating Gas Recovery and Separation Unit is a device used for rapid recovery and separation of mixed insulating gases such as SF₆/N₂. The unit adopts a modular design, is easy to integrate, and has multiple module combinations to meet different field operation requirements. It is suitable for on-site recovery and separation operations of medium and low voltage switchgear (10~40.5)kV gas-filled cabinets, high voltage (72.5~220)kV porcelain column circuit breakers, 500kV porcelain column circuit breakers, and 110kV gas-insulated switchgear (GIS).
▎Key Features ：
1.Gas pretreatment function: Capable of filtering and adsorbing micro-water, toxic/harmful decomposition byproducts, and impurities in mixed gases.
2.Recovery and rapid separation of SF₆/N₂ mixed gas, with post-separation SF₆ volume content reaching ≥99%, and SF₆ content in N₂ less than 100ppm.
3.Compressed storage of separated SF₆ gas into external containers.
4.Equipped with pure SF₆ gas recovery capability, enabling multi-scenario operations with a single device.
