CONVENTIONAL FULER’S EARTH TREATMENT

CONVENTIONAL FULER'S EARTH TREATMENT of transformer oil using oil filtering

  • Removes mechanical impurities and contaminants from the oil
  • Improves color of oil
  • Removes moisture and eliminates acidity
  • Refines the oil
  • Prolongs service life of transformer oil and of transformers themselves
  • Easy to mount and serve
  • Operates together with equipment for oil thermal vacuum purification of any capacity produced by Globecore

Application of fuler earth filter for mineral oil

Standard oil filtration systems using discolouring clays as filling material (fuller’s earth) are
designed to remove deterioration products from oil and to refine it.
