TECHNICAL DESCRIPTION OF EQUIPMENT.
The Unit (figure1.1) is an assembled container keeping all the junctions, components and aggregates. Container is the one- or biaxial trailer mounted. Front as well as back wall is lockable doors mounted for unobstructed access and fanning. Unit is supplied mounted on two-axial trailer equipped by torsional suspension axles, pneumatic wheels, coupling loop, support jacks, pneumohydraulic braking system, parking brake hand lever and electrical equipment.
There are the following components inside the frame: vacuum column 1, inlet oil pump 2, outlet oil pump 3, oil heater 5, fine filters 6, control panel (complete control unit CCU), vacuum pumps cluster, pipeline system with shutoff and control valves 4. To adjust parameters, Unit employs temperature controllers 2ТRМ «Оven» (equipped with ТСМ sensors), vacuum controllers RVE-4,1 (equipped with PМТ-6 lamps), both pressure and vacuum gauges(М1-М3). Vacuum pumps cluster (figure 1.2) is a frame mounted with one backing pump 7 and vacuum booster pump (Roots pump) 8. Vacuum pumps cluster joins vacuum column and oil trap as well as vacuum pipeline which is shut-off valve equipped.

|Control cabinet is designed for placement of electrical components to facilitate Unit operation. It is a metal cabinet with lockable door. Electrical control and commutation circuits are panel located inside. Control buttons and light signaling devices are installed on the cabinet. For control cabinet general view watch figure 5.
Figure 5. General view of control cabinet panel
- thermostat – for oil heater switch off if oil temperature is above 90 ºC set;
- flow relay – for oil heater switch off if no oil flow is supplied through oil heater;
- thermistor – for oil temperature measuring on heater outlet;
- manometers – to indicate contamination level of filter elements with regard to inlet and outlet pressure in fine filters;
- level indicators – to control oil level in vacuum column.
- oil pumping;
- oil heating and filtration;
- oil dehydration and degassing;
- vacuumizing of external equipment.
Testimonials about GlobeCore:
Y. A. Engineer at Electrical Company, Asia.
Professional solution to the problem of transformer oil purification, filtration and degassing is the products of GlobeCore. I recommend looking into the company’s offers.
HARRISON A. McCOY, III
CEO, U S Energy Initiatives Corporation, Inc. (OTC:USEI), Hawaiian Islands“We have been observing operation of GlobeCore for many years: these guys really do make outstanding equipment for transformer oil regeneration in the field. Transformer’s can be services without the need to shut them down. 1 micron filtration and drying to 2 ppm are really impressive”
