Description of Thermo-Vacuum Transformer Oil Purifier

PureTech Mobile Type Thermo-Vacuum Transformer Oil Purifier is designed to improve the quality of used transformer oil by removing moisture, gas, mechanical particles as well as other impurities, as the equipment that dehydrates and degasses used transformer oil in a high-vacuumed state.

This thermo vacuum type oil purifier is mainly used for high voltage power transformers 400/230KV with different power capacity varies up to 300 MVA, 230/66KV with different power capacity varies up to 125 MVA. The oil treatment plant is capable to re-improve the power transformer oil characteristics up the required or recommended value by transformer manufacturers or IEC standards. It is also often used to filtrate new transformer oil before filling into electrical transformers.



Performance of Thermo-Vacuum Transformer Oil Purifier

Water content can be decreased to below 5 ppm.

Gas content can be reduced down to below 0.1%.

• Multi-stage filter cartridges ensures a high filter precision of 1 micron in the oil.

Dielectric strength of transformer oil can be improved above 75KV.


Capacity of Thermo-Vacuum Transformer Oil Purifier

1. Oil flow rate ranges from 1,800 ltr/hr to 18,000 ltr/hr, suitable for various demands of transformer maintenance. For smaller capacities below 1800 ltr/hr, please refer to our model VOP (Single-stage Vacuum Transformer Oil Purifier).

2. At least two-stage Heating with thermostat, ensure uniform heating and prevent overheating.

3. Double-stage vacuum pumps create and maintain sufficient and high vacuum level inside the oil treatment plant, maximumly ensure the efficiency and effect of oil dehydration/degassing.

4. Multi protection settings, oil level in the vacuum chamber works together with electrical heater and solenoid valve, phase-break protection, etc.

5. Transformer oil purifier mounted on a mobile trailer makes it easy to access and operate in different transmission substations.

6. Transformer vacuuming can be performed by this oil treatment plant (OPTIONAL).
