The Des-Case Vacuum Dehydration Systems (VAC) are designed to remove 100% of free and emulsified water and at least 90% of dissolved water from petroleum and synthetic-based fluids. VAC systems remove 100% of free gases and least 90% of dissolved gases. What makes a Des-Case VAC system most unique is it’s designed for continuous, unattended duty and doesn’t require vacuum tower maintenance or costly coalescing filter element replacements – the tower is completely sealed and uses permanent dispersion media.

By maintaining absolute fluid cleanliness, you can dramatically increase the life of critical electric transmission components, maintain dielectric strength and condition of insulation, minimize downtime and maximize profitability.

A vacuum dehydrator can be properly sized to meet specific needs by evaluating the total volume of oil to be processed, the volume of water contaminating the lubricating oil, and the rate at which the water contaminates a system.


  • Designed to Remove Free, Emulsified, & Dissolved Water / Particulates / & Gaseous Contamination From Petroleum & Synthetic-Based Fluids
  • Water Removal Principle Used is Simple, Reliable, & Will Dependably Remove Water Well Below the Oil Saturation Point
  • Process Begins w/ Oil Drawn Into Unit & Heated
  • Oil Flows Through Permanent Dispersion Media Inside the Vacuum Tower & Exposed to Vacuum, Normally < 26″ Hg (660 mm Hg)
  • Next Water & Dissolved Gases are Boiled Off & Oil is Dehydrated
  • An Outlet Pump Removes Dry Oil From Bottom of Vacuum Chamber
  • Lastly, Oil Passes Through Particulate Filter Housing
  • Used to Filter Hydraulic, Steam Turbine, & Almost Any Other Industrial Oil System


  • High Holding Capacity
  • High Efficiency Filtration w/ Low Pressure Drop
  • Epoxy-Coated Steel Support Mesh Upstream & Downstream
  • Performance to ß<3(c)=1000 (Per ISO 16889)
  • Synthetic Media w/ Smooth, Rounded Fibers for Low Resistance to Flow
  • Excellent Chemical Compatibility
