Oil Cleaning

RRT Water Removal & Oil Cleaning Process

The contaminated oil is passed through heat exchangers by a pump that utilizes strainers for large debris removal if necessary. With flow rates of up to 2000 litres/hour we can quickly and efficiently handle all machine oil tanks etc., regardless of size.

The oil is introduced into the centrifuge (at 8000 rpm.) where free water and sub-micron particles are removed. Passing the oil through the vacuum distillation vessel completes the water removal.

With oil temperatures at approximately 50 to 70 degrees Celsius, all low boiling point liquids (water, solvents, etc.) and gases are removed in the form of vapour. The oil is then pumped through a 3-micron polishing filter. The volume is monitored by a flow metre upon exit from the unit.

For single pas modes, the reclaimed oil is delivered into a clean tank whereas in a multi-pass arrangement, the oil is returned to the recycling system to reduce the contamination level of the existing oil to flush the contaminants in the system. This usually requires up to three passes – dependant on the volume of oil in the tank.

Results And Reports

The final filtration station is capable of removing contaminants via 2-micron filters and the vacuum dehydration can achieve water levels to 0.005% or less, air and gas removal to 0.01% or less.

The final filtration station is capable of removing contaminants via 3-micron filters and the vacuum dehydration can achieve water levels to 0.005% or less, air and gas removal to 0.01% or less.

Typical results would be a particulate level of ISO 16/13 or 13/9 with water level at less than 0.005%. Confirmation of results is derived by laboratory analysis of before and after samples.
