How it Works

The purification system is designed to remove water (all three phases), solid particulate and dissolved gasses from petroleum and synthetic industrial oils. The water removal principle used is simple, reliable and will remove water well below the oil’s saturation point, even when tightly bound in emulsion. The schematic displayed to the left and below shows a typical Vacuum Dehydration System. The vacuum pump creates a vacuum that draws the industrial oil into the unit through an in-line heater, and it is then heated up to 66°C (150°F). It then flows through specially designed dispersal elements located inside the vacuum tower. The resulting thin oil film flowing across the dispersal elements and exposed to the vacuum, normally set at 635 mmHg (25 inHg), vapourises the water. Because the boiling point of water under vacuum is below the set oil temperature, it is left dehydrated or dry without affecting its ‘clean oil’ properties. An outlet pump subsequently takes the oil from the bottom of the vacuum chamber and pumps it through a high-efficiency glass media particulate filter and back into the equipment reservoir. The water vapour is drawn via a condenser, liquifies and drains into the condensate tanks.

The Vacuum Dehydration system’s mechanical components require little or no routine maintenance, making the unit very reliable. All components can be field repaired or replaced without special tools.
