Transformer oil purification system CMM-4T (with Raschig rings, capacity 4000 LPH)
GENERAL INFORMATION
Mobile oil units СММ-Т are designed for releasing insulating, transformer, industrial turbine and compressor oils of mechanical contaminants and water. Viscosity of the aforementioned oils should be 73-280 mm²/sec for the temperature of 50 °С. The plant’s configuration presumes oil heating.
The vacuum column of the given unit contains numerous polypropylene wheels regarded to be peculiarity of the unit. The leakage of the contaminated oil through the wheels results into the extra-thin oil layer permanently altering the surface. Vacuum decreases partial pressure of the oil water which rapidly evaporates either free or emulsified.
