CMM-4,0LT Transformer Oil Purification Unit

The СММ-4,0LT unit is designed for thermal vacuum drying and filtration of industrial oils used in lubrication, sealing, and hydraulic control systems of gas turbine and gas pumping units, gas engine compressors, and transformers. In addition to oil purification, the CMM-4,0LT can be used for heating and drying oil-filled electrical devices. The unit has a capacity of at least 4.0 m³/h (17.6 gpm) in thermal vacuum drying and filtration mode. The oil is drawn by vacuum through a coarse filter with a 200-micron filtration fineness into a vacuum tank containing a heater. Rising from bottom to top, the oil heats up and passes through a specially channeled lid into special fillers. As the oil flows downward through the fillers, moisture and gases are removed under vacuum. Finally, the oil is pumped from the bottom of the tank through two fine filters to the unit outlet, with filter fineness selectable at 5, 3, 1, or 0.3 microns.
