ENERVAC’s (transformer oil purifier) high vacuum process is used for the dehydration and degasification of electrical insulating liquids including transformer oils, polybutene and silicone fluids, to increase and maintain their dielectric strength. The processing includes the removal of free and soluble water, dissolved air and gases and particulate matter. The most important applications of high vacuum (transformer oil purification) degasifiers (transformer oil purifiers) are in the field of extra high voltage transmission and in the manufacture of electrical apparatus.

 

In addition, the high vacuum process is used in the degasification of cable oils including polybutene. Outside of the electrical industry, this process is used for electronic and radar equipment, vacuum pump sealing oils, brake fluids and refrigeration oils – including phosphate esters and silicones. Mobile and stationary units are available in sizes 50 to 6000 GPH (190 to 23,000 l/h).

Performance:

The typical performance in a single pass through an Enervac vacuum system is as follows: 

  • Dehydration—At minimum oil temperatures of 80° F the water removal is from 100 ppm to less than 10 ppm.

  • Degasification—Enervac vacuum oil purifiers reduce soluble air content in a single pass from full saturation of approximately 12% to less than 0.25%. Other gases in solution with oil, including combustibles, are also removed.

  • Particulate matter—The accelerator cartridge provides removal of particulate matter to a nominal 5-microns. The addition of a filter downstream of the chamber will remove particulate matter to submicronic size.

  • Other contaminants such as products of oil oxidation, thermal degradation, dissolved varnishes, paints and acids can be removed by the addition of Fullers Earth filters to the system.

Applications:

The most important applications of high vacuum degasifiers are in the field of extra high voltage transmission and in the manufacture of electrical apparatus for it. In addition, the high vacuum process is used in the degasification of cable oils including polybutenes. Outside of the electrical industry, this process is used for dehydration and degasification of oils for radar and electronic equipment, vacuum pump sealing oils, brake fluids, refrigeration oils—including phosphate esters and silicones.
