P-separators are based on purifier technology, which means that the oil/water interphase is manually adjusted by means of a gravity disc. Because the separators do not automatically adjust to varying oil density, they are most suitable for economical cleaning of the following:
- Lubricating oils
- Lighter diesel oils
If the oil is well defined and does not vary in density, P-separators can also be manually adjusted to clean heavy fuel oils with densities up to 991 kg/m3 and viscosities up to 600 cSt/50°C.
P-separators are designed for automatic operation in periodically unmanned engine rooms at sea and in automated power stations ashore.
