The SES522-500D 500 lb Adsorbent Treatment System (Fullers Earth) removes polar contaminants such as acids, oxidation by-products, and color bodies from numerous fluids. The bulk media system can be used for stand-alone treatment or in conjunction with the SES320 conditioning system to regenerate badly degraded ISO class III insulating fluids and with multiple passes, "desludge"  badly contaminated transformers.

 Insulating Oil Properties Restored

  • Total Acid Number (TAN)
  • Negative Neutralization Value 
  • Negative Interfacial Tension (IFT)
  • Color
  • Dissipation Factor
  • Eliminates Sludge and Oxidation Byproducts
  • Oxidation Stability * 

* Note: Polar additives, such as oxidation inhibitors, can be removed during adsorbent treatment processing.  Additive restoration requires an optional additive mixing and injection system.
