Oil is pumped into the treatment tank passing through the first particulate removal element.
Oil is drawn into the VDOPS by a high output vacuum pump. The oil passes through another particulate removal element and then onwards to a series of low watt density heaters where it is heated to an optimum 66ºC temperature for the dehydration process.
Next the oil enters the vacuum chamber passing through specially designed dispersal elements which create a thin film of oil that is exposed to vacuum. The boiling point of water is below the 66°C temperature at vacuum, so water and dissolved gases are “boiled off” and the fluid is effectively dehydrated.
Vapourised water is then drawn into the condenser where it becomes liquid and drains into the condensate tank.
The dehydrated oil flows to the bottom of the vacuum chamber and is removed by the discharge pump. The oil passes through a 3rd fine filter.
PROPEL Oil Management’s ’5 time multi-pass’ procedure maximises results by cycling the entire treatment tank 5 times.
Oil is then renewed by blending new additive content. Once blended, the oil is certified in preparation for return to the customer.
The VDOPS (Vacuum Dehydration Oil Purification System) machine is central to the PROPEL Oil Management process.
The VDOPS machine provides the foundation for lubricant filtration and dehydration. With a flow rate capacity of nearly 200 litres per minute it is capable of purifying the largest lubricant tanks quickly and efficiently.
- High efficiency filters that can achieve particle counts as low as ISO 14/12/9
- Vacuum dehydration can achieve overall moisture content as low as 20 parts per million
- Removes free, emulsified and most dissolved water
- No other utilities for on-site treatment other than electricity is required
- Additives are blended to filtered and dehydrated lubricant to restore the lubricant to as new specification or higher.
