GlobeCore Starts Producing New Transformer Oil Degassing Unit

GlobeCore is pleased to announce the introduction of the new CMM-0.5 oil degassing unit.

This CMM-0.5 unit has been designed and produced taking into account the demand for low cost, highly efficient units, intended for degassing dielectric transformer insulating oil.

The CMM-0.5 unit can be used for pumping, heating, and degassing of dielectric insulating oil, as well as removing mechanical impurities and moisture.  The processing capacity of the unit is 0.5 m3/hour.

The unit has a simple design that is easy to maintain and operate. The equipment consists of the vacuum column, ceramic heater, liquid pump, vacuum pump, and filtering system with replaceable cartridges.

* – any voltage available at customer’s request;

** – provided that the processed oil has not been in use.

After processing  transformer oil  with the CMM-0.5 unit, you can obtain the following oil results:

  • breakdown voltage not less than 60 kV (for the oil that has not been in use);
  • moisture content of not more than 10 g/t. If there are more stringent requirements for this value, it may be improved by increasing the number of oil processing cycles;
  • volumetric gas content of not more than 0.1% over several oil processing cycles.

Sensors have been installed in the unit so that the operator can control the pressure drop at the filters and control the amount of working vacuum.  The heating temperature can also be controlled through the use of a special regulator.

When processing/treating a transformer with high moisture content in the oil, there is always a possibility of foam formation, therefore, in order to avoid this problem a special type of protection is provided for in the unit.  If, for some reason, oil begins to leak or spill from the unit, the oil spill will be immediately detected by the “Oil Spill Sensor” and the unit will be shut down at the same alerting the operator with an alarm. .

You can order the CMM-0.5 unit right now. In case you are not satisfied with some of the technical parameters of the equipment, you can contact one of our managers, and then fill out a questionnaire, indicating all the necessary technical requirements that would meet your specific needs.
