To remove moisture, gas and particles in transformer oil, mutual inductor oil, cable oil, and circuit breaker oil, and restore property of insulating oil.

Suitable for high voltage project between 110-500KV

Power transformer oil purification machine is the key to transformer reliability, performance and longevity. Your transformer's insulating oil should be free from moisture, dissolved gases and particles that accumulate as the oil ages. Even some new oils may require treatment to limit these contents to acceptable levels.

Power transformer oil purification machine Performance:

Water Removal: Overall Water Content ≤5 PPM by removing free, emulsified, and dissolved water.
Particulate Removal: Particle counts as low as 1 micron.
Entrained Air and Gas Removal ≤ 0.3%
Acid Removal: can be equipped with fullers earth towers to neutralize acid and Lower TAN to < 0.03 KOH/g
Dielectric Strength:≥70 kV per ASTM 877

Features:

Two separating house made by stainless steel. Oil flow by rotation in stereo evaporation to degas and dehydrate well. (Patent no. ZL200420061085.6).

The combination of axial fan and condenser make vapor from vacuum pump and roots pump into water, it can prolong time to change vacuum oil while meet emission standard.

Multiple Filter Housings With Cartridge Style Filter Elements, big filtering area to hold more particles.

Control system: IEC standard with each wire marked. tri-unity control to avoid wrong operation as lack-phase, wrong phase and overload.

Oil level in vacuum tank is controlled by photoelectric switch, which is flexible and accurate. No oil-spraying. (Patent no.: ZL200420060973.6).
