Where Could the SF6 Gas Filtering Machine Be Used?

  1. The SF6 gas purifying device measure the vacuum and vacuum of the device and the electrical equipment.
  2. The SF6 gas filtering machine recycles gases from electrical equipment.
  3. The kind of machine can dry and purify the recovered and recharged SF6 gas.
  4. The equipment mainly inflates SF6 appliances.
  5. The equipment compresses and stores SF6 gas in electrical appliances.

Features of SF6 Gas Purification Machine:

  1. The design is advanced, the function is complete, the structure is reasonable, and the operation is simple and clear.
  2. Compression system: SF6 closed compressor with no leakage.
  3. The vacuum system uses a two-stage rotary vane vacuum pump with an automatic oil return prevention device in the system.
  4. The purification system adopts the principle filter of Japan CKD Company. The filter adopts electric heating and a built-in high-efficiency adsorbent, and the purification effect is more remarkable (no need to frequently change the adsorbent).
  5. The three-phase power supply of the electrical system of the device is automatically confirmed and automatically protected by phase failure.
  6. The device control system uses the latest technology SF6 special valve.
  7. The storage system is configured with 100–500KG liquid storage tanks according to user requirements.
  8. The device is mobile.
  9. In addition to SF6 gas purification machine, we can also provide oil filtration equipment such as lubricating oil purifier, transformer oil purifier and so on.
