Features of SF6 Gas Purification Machine

  1. The equipment has an advanced design, complete function, reasonable structure, and user-friendly operation.
  2. It uses an SF6 closed compressor system to prevent leaks.
  3. The vacuum system features a two-stage rotary vane vacuum pump with an automatic oil return prevention mechanism.
  4. Purification employs a principle filter by Japan CKD Company, with electric heating and a high-efficiency adsorbent, reducing the need for frequent changes.
  5. The electrical system has an automatic confirmation and phase failure protection for the three-phase power supply.
  6. The control system integrates the latest SF6 special valve technology.
  7. The storage system can be customized with 100–500KG liquid storage tanks based on user requirements.
  8. 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.
