Hi-Vac Solutions To Transformer Oil Contamination

Transformer Oil Purifiers, Conditioners, and Reclamation

Transformers oil conditioners, purification and reclamation addresses the higher cost for oils and ever increasing environmental regulation and liability. It is no longer economical to replace electrical insulating oils to renew their dielectric strength. Restoring these oils to their original strength through purification is now a necessity. High Vacuum (Hi-Vac) Transformer Oil Purification Systems are designed specifically to meet the operational, economic and environmental needs of industry in purifying insulating oils. Through proven dehydration, degasification, and filtration techniques, the Hi-Vac Oil Purification Systems quickly and easily remove:

  • Free and emulsified water to less than 10 ppm
  • Free and dissolved air and gases to 0.25% of total gas content
  • Particulate matter to 0.5 microns nominal (2.8 microns absolute)
  • Other contaminants using unique media designs
And operation is a snap. Hi-Vac Systems are easy to use and require very little maintenance. Even replacement elements are very inexpensive. Hi-Vac Systems can be used as stationary units or manufactured within a variety of trailer configurations to be completely portable.
