Summary

  • SpankRanch has devised an ingenious method of removing water from oil using a retired gas cylinder welded to a steel frame to form a vacuum dehydrator.
  • He used a gas cylinder because they are manufactured to extremely high standards of thickness and are therefore ideal for containing pressure when the vacuum is pulled.
  • The neck of the cylinder is pointing down, with a fill port in the bottom, and the side of the tank has been drilled and threaded for various valves, including a port for a vacuum pump.
  • The hacked machine works by heating up the oil in the tank and pulling a vacuum, which allows the water to be gently boiled off without “cooking” the oil, and the process takes a few hours to treat a 10-gallon batch.
  • This is a cost-effective and timesaving solution for dealing with contaminated hydraulic fluid in heavy equipment.
