    This CMM 4/7 mobile oil processing unit is designed for degassing, removal of solids and heating of oil for power transformers with voltage up to 1,150 kV.

    The unit can be used to:
    1) heat electrical systems that contain insulating oil with hot oil;
    2) for vacuum drying of transformers and
    3) for vacuumizing.

    The unit is best suited to facilities that install, repair and service oil filled electric power transformers and other oil filled electrical equipment.

    The unit is not certified for use in and around explosive gases, toxic gases or other aggressive environments.

    When indoors or other enclosed spaces, exhaust gases must be vented to the outside through hoses or pipelines.
