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.

СММ-4,0LT unit is designed for thermal vacuum drying and filtration of industrial oils used in lubrication, sealing, hydraulic control systems of gas turbine and gas pumping units, gas engine compressors, and in transformers. In addition to oil purification, CMM-4,0LT may be used for heating and drying the oil-filled electrical devices.

Principle of operation

The oil driven by vacuum passes through a coarse filter with the filtration fineness of 200 microns after which it gets inside a vacuum tank where a heater is located. Rising from bottom to top, the oil heats up and gets into the other part of the chamber through a special channeled lid coming directly to special fillers. Next, the oil flows down the fillers, while the moisture vapor and gases are removed from the oil by vacuum. Then, the oil is pumped out from the tank bottom through two fine filters to the unit outlet. The filtration fineness of the filters can be selected at 5, 3, 1, or 0.3 microns.

Design features

The heater is located inside the vacuum tank which made it possible to reduce the unit dimensions and to diminish the heat losses while heating the oil.

The oil is sucked into the vacuum chamber due to the underpressure generated by a two-stage vacuum system consisting of a backing pump and a booster pump. A new layout has been applied to the rest of the unit components. All of these innovations have given good results in terms of the small equipment size.
