SESCO designs and manufactures high-efficiency vacuum dehydration systems for industrial lubricants used in high water contamination environments.  The SES300S purifier is a high-efficiency vacuum distillation system.  Compared to the typical "mass transfer" vacuum dehydrator the SES300S will remove 5X-10X the amount of water contamination per pass. Water contamination from seal failure can force costly outages and lost production. The SES300S can be used to offset significant water ingression problems, allowing the repairs to take place during scheduled maintenance outages. Equipment payback can be immediate.
