Unidade de desgaseificação móvel CMM-6/7
The СММ-6/7 is designed for purification of electrical insulating oils, removing water, gas and solid particles, and for transformer evacuation.
This unit is normally used during installation, operation and servicing of oil-filled high voltage equipment (transformer, high voltage switches etc).
The unit can be operated in the following modes:
- transformer heating: in this mode the oil is filtered and heated;
- oil degassing: this mode is for filtration, drying and degassing oil;
- transformer evacuation.

* Note – Initial oil quality parameters:
- gas content: below 10.5% vol
- water content: below 0.005% (50 g/t)
- temperature: above 0 ºС.
** Todo o equipamento fornecido nos EUA usa 60 Hz de corrente alternada.
- versatility;
- no need to use adsorbents for transformer oil drying;
- no air pollution and no waste streams to dispose of or store;
- simple operation and servicing;
- best oil quality even after one processing cycle;
- low power requirements;
- low noise levels.
