Vacuum Oil-Purifiers AEHV

AEHV Oil Degasser

The most important application of the high-vacuum degasser is in the field of high-voltage transmission and in the manufacture of electrical devices. In addition, the high vacuum process is used in the degassing of oil cables including poly-butanes. Outside the electrical industry, this process is used for the dehydration and degassing of oil for radar and electronic equipment, oil-sealed vacuum pumps, brake fluids, cooling oils - including phosphate esters and silicones. Amperis offers the AEHV Oil Degasser designed for maximum job efficiency, expertly proven performance, requires minimal maintenance and is fully serviced. All this is thanks to the full support of Amperis' specialist technicians, plus the "know-how" and thorough research that makes the AEHV a Unique Degasser. Designed for unattended operation and suitable for operation on energized equipment - full equipment monitoring is an option.

Features

Description of the process:

  • The oil is introduced into the vacuum chamber, where water, air and dissolved gases and other low-boiling volatile contaminants are removed. Special chemically inert accelerator cartridges are used to perform the following functions in the vacuum chamber
    1. First, its detailed structural design allows the water to be quickly separated from the oil by the coalescer even before it reaches the evaporation state.
    2. Second, millions of glass fibers between 3-10 micrometers in diameter provide a large surface area for exposing the thin oil film to a vacuum.
    3. Third, sharp points of the fiberglass provide a quick release of oil gases and vapors.
    4. Fourth, the elements act as a proper filter by removing solid contaminants. The cartridges are easily replaceable.
  • This method is more efficient than the previous method, which used nebulizers and baffles that required several passes to obtain the same degree of degassing.

Performance:

  • The typical behavior of the achieved HVA is:
    • Dehydration-at a minimum oil temperature of 27ºC water removal is from 50 ppm to less than 5 ppm.
    • Degassing-Reduces the soluble air content from a full saturation of approximately 12% to less than 0.25%.
    • Standard Particle-Filter Subject provides 0.5 micron filtration
  • Other contaminants such as oil oxidation products, thermal degradation products, dissolved lacquers, paints and acids can be removed by adding the extra option of the more complete earth filters.
