Compact vacuum systems with total or partial water recirculation
OilSys is an engineered system for the installation of a total recirculation liquid-ring vacuum pump that uses mineral oil (or similar) as operating liquid, in order to guarantee maximum flow rate and vacuum performance higher than those allowed by water.
It is composed of:
The gas handled by the vacuum pump is discharged with some of the service oil into the special frame which acts as gas/oil separator and allows separation from the oil of any evacuated condensables.
The oil is returned to the vacuum pump by means of a circulation pump after being cooled through the heat exchanger.
The gas is vented after being filtered of any oil through the specially engineered oil demister filter. A pressure gauge at the filter housing will indicate over pressure when the oil demister filter is plugged and needs replacement.
