CMM-1/1 Mobile plant for insulating oils

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 transformershigh 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%.

  • Compactness. Due to that fact, the unit can be transported by various means of transport (land, water, air) and won’t take a lot of work space.
  • Ease of maintenance and operation. Only one person is required to work with CMM-1 and we can fast and easily teach your staffl how to operate the unit. The constant presence of an operator is not necessary.
  • It can raise the breakdown voltage of insulating oils from 15 to 75 kV in several passes.
  • It has an increased heating rate due to the optimal design of the heater.
  • The big size of the viewing glass window allows you to visually observe and control the process of oil purification.
