The CMM-6D degassing unit is designed for removal of particulate matter as well as heat and vacuum purification of electric insulating and turbine oils from water and gas.

The unit is intended for use during installation, repairs and operation of oil-filled high voltage equipment up to 1150 kV (power transformers, high voltage switches etc).

For indoor operation, ensure exhaust of removed gases into the atmosphere via piping.

Description of the unit

The unit is a self-contained unit with all assemblies and components in the container. The container is installed on a trailer. Side walls of the container feature doors for simple access and ventilation. A compartment for tools and accessories is attached to the side wall of the unit; the compartment also contains drums with power cable and oil hoses.

The unit operates in one of the following modes:

- «MANUAL MODE»;

- «HEATING FILTRATION MODE» - transfer of oil with heating and filtration;

- «DEGASING MODE»;

- «VACUUM MODE» vacuum evacuation of other equipment;

- «OUT VACUUM MODE» - simultaneous degassing and vacuum evacuation of other equipment.
