This GlobeCore mobile oil processing unit is designed for degassing¹, removal of solids and heating² of oil for power transformers³ with voltage up to 1,150 kV.

The unit can be used to: (1) heat electrical systems that contain insulating oil⁴ with hot oil; (2) for vacuum⁵ drying of transformers and (3) for vacuumizing⁶. 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.
