Double Stage High Vacuum Electric Insulating Transformer Oil Filtering Machine/ Waste Oil Regeneration System

Single stage vacuum VS. Double Stage Vacuum
Under normal circumstances, single stage vacuum oil purifier is effective. However in exceptional cases where a higher state of vacuum is required to maintain low value of dissolved gases and moisture after oil treatment, double stage high vacuum oil purification machine is needed. 

Machine function:
Remove free and dissolved water, gases, acid, sludge, solid and metal particles, etc.
Improve oil color to make it have better appearance.
3.Maintain dielectric strength; the oil will have much higher breakdown voltage and improve coefficient of loss tan delta after treatment.

Special Features:  
1. Alarm Annunciator 
2.Transformer evacuation system
3.It can purify transformer oil on-line without power cutting off.
4.Duplex 3D stereo-evaporation to fast eliminate the moisture. 
5. Especially applied to vacuum oiling and drying for power transmission equipment which are over 110KV
6.Can be operated both on-load and off-load.
7.Can be operated fully-automatically with PLC controller.
8.This Oil Filter Machine can be made in hermetical, canopy-covering, open and frame style.

Guaranteed Value after Treatment:
Breakdown Voltage≥75KV
Moisture content≤3PPM
Gas content≤0.1%
Impurity size≤0.5 micron(no free carbon)
IFT≥40dynes/cm
Acid value≤ 0.03mg KOH/g
Dielectric loss factors≤0.001tgδ(90℃)
Colour≤0.5L

Optional:
The unit can be produced in accordance with specific requests of the Client(additional vacuum pump, additional heater, weather-proof enclosure trailer for road transportation etc.).
