For Class III oils that are service aged, Fuller\u2019s earth treatment will be required. \u00a0Color number, Acid Neutralization Number and Interfacial Tension are good indicators of the condition of Class III oils. \u00a0Fuller\u2019s earth processing systems are available in a variety of configurations sized to the flow rate of the vacuum oil purifier. \u00a0They can be incorporated into the purifier system itself or provided as a separate module to be connected and used only when needed.<\/p>\n

Fuller’s earth<\/h2>\n

Fuller’s earth can be used to decolorize and neutralize any petroleum oil, especially dielectric insulating oils. \u00a0It also excels in neutralizing traces of strong inorganic acids. \u00a0Due to the relatively large pores found in Fuller’s earth, it is well adapted to the removal of high molecular weight sulfonates, resins and asphaltines.<\/p>\n

Transformer oil will discolor as oxidation takes place. \u00a0Color, by itself, is not a reliable test in evaluating the condition of the oil for further use. \u00a0It is however, a strong indication that something is happening within the transformer that requires investigation. \u00a0Once transformer oil changes from the yellow color range into the orange and red color range, it has degraded to the point where the vital parts of the transformer are being seriously affected.<\/p>\n

As the color of the oil changes, sludge is forming in solution with the oil due to oxidation. \u00a0This causes a drop in interfacial tension and an increase in the acid (neutralization) number. \u00a0When transformer oil deteriorates to the red color ranges, deposited sludge continues to oxidize and harden, blocking vents and insulating cooling fins, causing higher operating temperatures. \u00a0Solid Insulation shrinkage may take place, and premature failure is likely.<\/p>\n

Care<\/b><\/h2>\n

GlobeCore<\/i><\/b> provides the service of Fuller’s earth filling and replacing in your equipment. \u00a0Care must be taken not to expose the Fuller’s earth to humid air or moisture. \u00a0This causes the clay to loosen its granular structure and can turn it to plain mud. \u00a0It is recommended that the clay be purchased in vapor-insulated bags to keep it dry. \u00a0For best performance and flow rate, oil should be supplied to the filters at a temperature of between 160 to 180 degrees F and a supply pressure capability of up to 80lbs. psi.<\/p>\n
