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