The SES522 Adsorbent Treatment Systems (Fullers Earth) remove polar contaminants such as acids, oxidation by-products, and color bodies from numerous fluids. The bulk media  systems 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. The SES522 systems are available in three tower sizes as well as in dual and single tower configurations.

The SES425 manifolds are designed for use on transformers with Qualitrol pressure relief valves. Evacuation and  Evacuation with hot oil spray versions are available. With an all aluminum construction, the SES425 series are easy to handle and maneuver into position on site. If Qualitrol pressure reliefs are not used the SES425 series will be custom designed to your specifications.
