This GlobeCore mobile oil processing unit is designed for degassing1Transformer oil degassing is a complex of processes targeted at the removal of water, gasses, and mechanical impurities from the dielectric oil., removal of solids and heating2Oil heating is used for treatment of oil in degassing, drying and regeneration machines to accelerate the process. Dehydration is based on the difference of water and oil boiling points. Since water boiling point is lower, heating can evaporate that water from the oil before the boiling point of oil is achieved. of oil for power transformers3A transformer is a static electrical device that transfers electrical energy between two or more circuits. with voltage up to 1,150 kV.

The unit can be used to: (1) heat electrical systems that contain insulating oil4Insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties. with hot oil; (2) for vacuum5A transformer is a static electrical device that transfers electrical energy between two or more circuits. drying of transformers and (3) for vacuumizing6Vacuuming is carried out to remove moisture inside the transformer or to protect it from moisture.. 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.

Manual performance adjustment by valves (or smooth performance adjustment, see option). Functioning in semi-automatic modes. Stepped or smooth (see option) oil heating. PLC control

Automatic performance adjustment. Functioning in automatic modes. Smooth oil heating. Control from PLC + HMI

Frame open design

Shell is available

Performance adjustment with manual valves

Performance adjustment of the vacuum pump is executed with a regulator on the control panel by means of a valve with an electric drive. Visual monitoring of the flow rate is by the flow meter indicator

Performance adjustment of the vacuum pump is executed by setpoint selecting at the control panel screen for maintaining the level in the vacuum column. Setpoint is kept constant by means of a valve with an electric drive. Pump operation is smooth throughout the entire control range. There is a digital meter to control oil flow

The controller program switches the heater stages by contactors according to the algorithm. Operator sets the temperature and it is kept constant automatically

Solid state relay (SSR) adjusts the heater stages' current smoothly and non-contactly. The P-Int-Derivative Controller

Online monitoring the transformer tank oil level. Automatic shutdown of the procesing unit and automatic block of the oil hoses in case of an accident. Automatic performance adjustment option. Automatic smooth direct heating option
