The SES320R family of insulating oil reclamation systems is designed to reclaim or "regenerate" severely degraded  ISO/ Group III insulating oils. SES320R insulating oil reclamation systems can be used to completely reverse the harmful effects caused by aging, oxidation, acid accumulation, sludge formation, and sludge precipitation. The SES320R adds an additional Adsorbent Treatment processing stage (Fullers Earth) to the SES320 conditioning systems. The SES320R oil purifiers can be used for either oil conditioning or complete oil reclamation.

SES320 Oil Properties Restored

  • Water content
  • Gas content
  • Dirt content
  • Breakdown voltage

SES320R Additional Oil Properties Restored with Adsorbent Media Treatment Phase.

  • Neutralization value (TAN)
  • Interfacial tension (IFT)
  • Color
  • Dissipation factor
  • Oxidation Stability (Optional)

We offer two types of Adsorbent Treatment stages for SES320R insulating oil reclamation systems. Both restore oil properties equally. The first type use cartridge or bulk adsorbent fuller's earth that is replaced once spent. 


Cartridge Media

  • The SES320RC uses replaceable adsorbent media cartridges. The cartridges are replaced when the media is spent.  Cartridge media can be used with system flow rates up to 600 GPH. 


Bulk Media

  • The SES320RB systems use bulk replaceable adsorbent (Fullers Earth) media and can be used for both oil reclamation and oil reconditioning. The media in this system must be replaced when spent. The SES320RB is targeted for transformer oil service where oil reclamation may be required.  This versatile system can be used for single-pass dehydration, multi-pass reclamation, transformer evacuation, and vacuum filling. Flow rates are available up to 50 GPM (11,400 LPH)

The SES320R mounting options will be the same as the equivalent size SES320 


  • Skid Mounting
    Built-to-order skid-mounted equipment can normally be built to meet customer footprint and access requirements.  Consult SESCO with special requests.
  • Enclosed Deck over Axle Cargo Trailer Mounting
    Unlike a standard cargo trailer, the equipment deck on a “deckover” cargo trailer rides above the axle assembly and incorporates a leaf spring or air bag suspension. The “deckover” design accommodates wider, longer, and heavier equipment payloads. All “deckover” cargo trailers are specifically engineered to accommodate equipment load and weight distribution to provide optimum towing conditions. Weight capacities (GVRW) range from 20,000 to 30,000 Lbs. SESCO will provide the trailer size and weight capacity options available for the system being quoted.
  • Dry Van Trailer Mounting
    The size and weight capacities of a dry van trailer accommodate a wide variety of options and equipment accessories.  Dry van trailer packages are specifically engineered to accommodate equipment loading axle weight distribution regulations.
  • ISO Shipping Container Mounting
    Equipment can be permanently or temporarily packaged in standard ISO shipping containers to facilitate ocean transportation. Containers are available in standard lengths.  If the equipment is permanently mounted, non-standard access doors and other openings must be installed at the destination. Installation design and material kits are provided. On land the containerized equipment is transported using standard ISO container chassis built to meet the local highway standards of the destination country.
  • Cargo Trailer Mounting
    All cargo trailers are specifically engineered to accommodate equipment load, weight distribution, to provide optimum towing conditions. Cargo trailer weight capacities (GVRW) range from 4,000 to 16,000 Lbs. SESCO will provide the cargo trailer size and weight capacity options available for the system being quoted.
