Transformer Oil Purification Systems



  • Easy to Use
  • Removes Emulsified and Dissolved Moisture to Below 5 ppm
  • Greatly Reduces Combustible Gasses and Oxygen
  • Completely Restores Dielectric Strength

Thermo Vac GEN 2 Vacuum DehydratorOur easy to use Thermo-Vac is used to degas, dehydrate, filter and restores dielectric strength insulating oil with the push of a button. Total Acid Number (TAN) correction options are available.  Our fully automated system takes the guesswork out of the process. The PLC starts and stops each component in the proper order. We have made oil purification easy.

The Thermo-Vac GEN 2 design maximizes contamination removal by using heat, vacuum level and increased surface area (as well as void space within the vacuum chamber). Our standard system features a single stage 0.5 torr vacuum pump (0.05 torr with High Vacuum Option), stainless steel horizontal vacuum chamber and particulate removal down to 0.5 micron. We have mastered economy with quality components so that performance is maximized and within budget.
