Technological solutions and equipment for maintenance of lubrication oils of large machines, eliminating micro particles, gases and water, increasing the useful life of lubricants, drastically reduce wear and minimize adverse environmental factors. It applies turbines, turbo and motor compressors, hydraulic systems, gearboxes, transformers, etc. Also for the oil water separation, using heavy equipment was water and all down stream operations, ver to be necessary remove hydrocarbons from the water.
