CMM-1H Oil Processing Unit
The СММ-1Н unit is designed for drying, heating and filtration of mineral transformer oil, as well as evacuation of transformer tanks.
The process is based on application of heat and vacuum. The oil is heated and pumped to the vacuum chamber. The low pressure in the chamber makes the water in the oil boil and evaporate. The water vapor is removed with vacuum pump exhaust.
The СММ-1Н unit consists of the following elements: a frame, a centrifugal oil pump (output), a vacuum pump, an electrical control cabinet, a vacuum chamber, filters, an oil trap, piping, an instrument panel, an oil inlet and an oil outlet.

*Note – Initial oil quality parameters:
- gas content: below 10.5 %;
- moisture content: below 0.01 % (100 ppm);
- temperature: above 0 °С.
- the unit is equipped with a centrifugal output pump to reduce noise;
- the unit does not have an input pump, the oil goes directly into the unit with reduced risk of leaks;
- simple operation;
- a porous inset in the vacuum chamber facilitates efficient moisture separation;
- the smart heating system varies current for the required processing rate, eliminating voltage surges;
- a water condensate collection container is installed;
- the unit features a separate outlet for transformer evacuation.
