The CMM-1/1 continues the excellent functionality of this series of equipment, but is designed to be more compact and economical.
The CMM-1/1 purifies electrical insulation oil with viscosity below 70 cSt at 50o, removing water and particulate matter.
This device can heat oil-filled electrical equipment with hot transformer oil and evacuate air from vacuum systems.
The unit ensures oil purification according to class -/14/12 from initial class -/18/16 (contaminant content by weight less than 0.004%) after multiple passes of the product through the filters.
The CMM-1/1 is used in the course of commissioning, repairs and operation of oil-filled high voltage systems (power transformers, high voltage switches etc).

Note: * Initial oil parameters:
- moisture below 0.005% (100 ppm);
- oil heated to +60±5ºС for 30 minutes;
- gas content below 10%.
- compact size. The unit can be carried by various vehicles (ground, sea, air);
- simple operation and maintenance;
- increase of dielectric strength from 15 to 75 kV in several passes;
- optimized heater design with increased heating rate without excessive power requirements;
- sight glass of sufficient size for simple visual monitoring of oil processing.
