GlobeCore Transformer Oil Purification Plant CMM 4.0 A
Removes Water from 100 parts per million lower to 10 parts per million and from 50 parts per million to five parts per million in one pass (ASTM method D-1533)
Reduces Gas content from fully saturated with air (ten to twelvePercent by volume) to under .1% (ASTM D-2945)
Removes Particulate Matter to five microns as standard or lower to .3 micron (optional)
Enhances dielectric strength as much as 75 kV
GlobeCore CMM (UVM) 4 m3/h – High Vacuum Degasifier created for elimination of solid contaminants, free and dissolved water and gases from transformer, lubricating, turbine and compressor oil.
Globe Core CMM (UVM) 4 m3/h has the capacity to process oil on tank to tank basis or on vitalized or p-vitalized transformer. Trolley or roadworthy trailer mounted, semi-automated, fully automated (PLC controlled) and explosion proof versions of the unit can be found. Optional equipment includes moisture probes, flowmeter with totalizer and .3 micron fine oil filter.
GLOBECORE OIL PURFICATION PLANT COMPONENTS DESCRIPTION
Vacuum Chamber Vessels and all sorts of interiors are constructed with carbon steel and have Coalescers, Sight Glass, Oil Level Controller, Foam Sensor and Vacuum Gauge. Vacuum Chamber’s rigid design causes it to be appropriate for stationary and mobile installation. Appropriate flexible connections are supplied towards the outlet pump and inlet pump to reduce negative aftereffect of vibration throughout plant operation and transportation.
Coalescers – built-in coalescers are supplied for that maximum exposure of oil towards the aftereffect of vacuum. Because of reduced pressure dissolved water and gases are vaporised through secondary chamber and filter into atmosphere.
Secondary Chamber (Oil Trap) – can serve as safety feature to make sure that no oil is drawn in to the vacuum pump.
Vacuum Gauge – is supplied to watch Vacuum level within the Vacuum Chamber.
Oil Level Controller – includes three capacitive probes presented to maintain needed degree of oil within the Vacuum Chamber.
Foam Sensor – rarely, under certain conditions oil foaming may develop. Once the Optical Sensor set up in the Vacuum Chamber picks up higher level of froth it’ll actuate a Solenoid Operated Valve to lessen vacuum and foam level.
Vacuum ports – vacuum connection is supplied to drag vacuum on transformer.
50 kW Oil Heater has two stage heating facility with 25 kW of energy each. A minimal watt density heating elements (1.2 W/cm2) are utilized to prevent warmth degradation of oil. The heater is controlled be electronic temperature controller.
Instrumentation and Controls
“Calpeda” Centrifugal pumps with energy use of 4 kW and capacity of 12m3/h are employed to draw oil interior and exterior the vacuum system. All electric motors are safe by overloads.
A Mesh Strainer is supplied to get rid of large contaminants that may damage the Inlet Pump. 5 microns Coarse Filter is a component of admission to the Vacuum Chamber. Oil receives its final treatment by passing with the Fine Filter made to remove 99.9% of contaminants bigger than 2 microns or 1 micron (optional).
Alarms and Interlocks
GlobeCore CMM oil purification plants feature the next safety devises which ensure easy and reliable operation and can securely shut lower the machine just in case associated with a alarm situation:
Higher Level Alarm – will alert plant’s operator by initiating seem and lightweight sensors and shut lower the machine securely should higher level of oil persist.
Low-level Alarm – interlocked using the inlet pump low-level alarm will securely shut lower the guarana plant just in case of inadequate oil level.
Flow Sensor – only triggers the Heater when oil flow is detected.
Foam Sensor – prevents excessive foaming
Overloads – all motors are safe by overloads.

GlobeCore Fuller’s Earth cartridges (ZP-260)
GlobeCor Fuller’s Earth systems are specially engineered to remove soluble contaminants such as acids, waxes, gums, resins, carbon residues and colloidal particles from transformer oil. They are designed for oil polishing after purification. For large quantities of oil GlobeCore regeneration system is recommended.
The transmitter provides on-line transformer oil measurement of both the moisture content and the temperature. The unit comes complete with a display showing the level of moisture in a “ppm” readout.
Influx Florack flowmeter gives a reading in m3/h and totaliser shows the total flow passed in a time through the meter.
GlobeCore CMM oil purification vegetation is installed on a double axle roadworthy trailer engrossed in a tent or made from steel sidewalls with raise doorways.
Triple axle semitrailer comprises CMM oil purification plant, on-board generator with gas tank, air-conditioned and heated operator’s room.
Sensors – seem and lightweight alarm with silence button will alert plant’s operator associated with a emergencies.
