The machine is designed for transportation and filtration of mineral and synthetic electrical insulation oil and for adding oil to transformers.


The machine is built on a wheeled frame with a hitch for towing on hard surfaces.

The machine includes two 200 liter (52 gallon) containers for oil storage and transportation. Pumps are installed for oil transfer.


The СММ-600CF machine purifies transformer oil by combined effects of filtration, heat and vacuum. The system is equipped with five filters:

  • a mesh filter for large particles;
  • a coarse inlet filter;
  • a fine filter at the outlet;
  • two filters to remove water entering the oil from the air.

Air bubbles are removed from the oil in the vacuum chamber.


Operation is managed by a PLC controller, which can identify the following faults:

  • frequency converter not ready or motor protection trips;
  • oil spill;
  • level sensor disconnect;
  • overflow in either of the containers;
  • vacuum chamber level sensor fault;
  • foam sensor activation in the vacuum chamber.

Any of these faults stops the machine. This condition is signaled by a sirene, a flashing light in the corresponding button and a text message on the controller screen.

Who this equipment is designed for

The СММ-600CF is designed for clients who specialize in transformer and other oil filled equipment servicing and repairs (including high voltage switches, OLTC, oil reactors etc).
