General

Sanmi On-Line Vacuum Oil Purifier is designed to purify the onload transformer.
Through the dehydration, degassing and fine filtration process, the dissolved water, dissolved gases and particles can be removed completely to upgrade the properties of transformer insulating oil.
With special tool and interlock safety system equipped, Sanmi on-line vacuum oil purifier is ideal for heavy duty transformer that unable to shut down the power.

Features

1. On-line Vacuum Oil Purificiation without need to shut down the operating Transformer.
2. Foam control and interlock alarm system ensure the safety oil purification process.
3. No air bubble generate during operation
4. Fully automatic operation with PLC control enable for unsupervision on-line oil purification.
5. Free maintenance in vacuum chamber
6. Flow Rate selection switch (5 types selectable)
7. Easy operation

Performance
