Vacuum Dehydration System

Brand: Lubrigard
Part Number:


The purpose of the FD-5 Vacuum Dehydration System is to serve as an oil treatment system. By removing water (dissolved, emulsified and free), gasses and solid contaminants the oil can return to its original condition, and be reused in lubricating systems. Having clean, dry oil will allow hydraulic and lubricating systems to perform more efficiently and can result in significant financial gains. The need to purchase new lubricating oils can be reduced and in some cases eliminated completely.

To begin, the oil is brought into the chamber and passed over the heater and heated. It then is dispersed over the Pall Rings , located inside the tower, and then exposed to a vacuum, usually between 22-25"Hg.

After the oil has been degassed and dehydrated it is pumped out of the bottom of the tower via the hydraulic pump into the filter to remove any contaminants before it enters the reservoir or system again.

In order to optimize this process the FD-5 Purifier is partially automated with a PLC and series of electrically controlled switches. Data, diagnostics, alerts and many help screens can be accessed on the control panel touch screen display.

Typical Applications:

  • Filtering Pulp and Paper lube systems
  • Filtering steam turbine lube systems
  • Filtering hydraulic reservoirs
  • Filtering rolling mill lube tanks
  • And many other industrial applications containing oil

Typical Industries:
