This SES522  Dual Tower 500 Lbs 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.
