Oil Processor Upgrades

SESCO can upgrade your aging oil processor. Upgrades can range in scope greatly. Most are typically minor. There are many factors involved but even major upgrades salvaging only functional major components make economic sense under the right circumstances. 

Lube Oil Purifiers

SESCO designs and manufactures high-efficiency vacuum dehydration systems for industrial lubricants used in high water contamination environments.  The SES300 purifiers are high-efficiency vacuum distillation systems.  Compared to the typical "mass transfer" vacuum dehydrator the SES300 will remove 5X-10X  the amount of water contamination per pass. Water contamination from seal failure can force costly outages and lost production. Properly sized, the SES300 can be used to offset significant water ingression problems, allowing the repairs to take place during scheduled maintenance outages. Equipment payback can be immediate.

Fullers Earth Systems

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.

Oil Booster Pumps

SESCO SES330 series inlet oil booster pumps are low pressure, low suction head, portable booster pumps designed to assist oil processors when circulating oil through a partially filled transformer being held under full vacuum. The SES330 is available in centrifugal and positive displacement pump versions. 

Transformer Vacuum Manifolds

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.

Oil Booster Heating Systems

The SES460-2400  booster oil heating system is a versatile oil heating tool designed to aid oil processing in cold weather transformer installation and maintenance.  The SES460-2400 can be set up to boost oil processor return or supply temperatures. It also can be being used as a stand-alone 40 GPM heating circulation system for preheating transformers and storage tanks in cold conditions. The variable speed positive displacement pumping system tops out at 40 GPM.  Three individually controlled 32 kW low watt density heating banks provide 96 kW of heating capacity.  When supplied by an oil processor (or pump) a pump bypass circuit is provided to allow the system to be used as a push through heating system.  A  weather-protected NEMA 4X control panel is provided.
