Redragon - Model HVD Series - High Vacuum Degassifier
The HVD series of degasifiers uses the only known method for reducing all three primary contaminants by treating the transformer oil; the thermo-vacuum process.Transformer oil is drawn in to the degasifier by means of low pressure created either by an inlet pump of a vacuum pump or combination or both. The oil is heated to reduce its viscosity and allow it flow through the rest of the system at a lower pressure. A magnetic strainer typically removes coarse particles larger than 20 microns.This is the first stage required to remove the solid contamination. The filtered oil is fed into a vacuum chamber where, due to the reduced pressure above the liquid, dissolved water is vaporized. The reduced pressure also facilitates the removal of any entrained gases in the oil.
