Purpose: can be used to decolorize and neutralize any petroleum oil, especially electrical insulating oils. It excels in neutralizing traces of strong inorganic acid. Due to the relatively large pores in fullers earth, it is well adapted to the removal of high molecular weight sulfonates, resins, and asphaltines.
Description: Baron fullers earth systems efficiently correct power factor; neutralization (acid) number; interfacial tension and color in dielectric oils. They are available as stand-alone systems with pumps and heat or integrated into a Baron HV transformer oil purifier.
The BA‐CL family of fullers earth systems are available in a variety of sizes and types including stationary and mobile versions.
The flow rate of transformer oil through fullers earth is a function of oil temperature and available pressure. The table below gives average flow rates with an oil temperature of 160 – 180 Degrees F at a pressure of 75 – 80 psig. Other oils may differ depending on their viscosity:
Baron fullers earth are bulk systems with user-replaceable media. Baron does not produce nor recommend systems that use high heat to regenerate spent fullers earth.
