Transformer Oil Purification Plant CMM 0.6

• Removes Water from 100 ppm down to 10 ppm in a single pass and down to 5 ppm after 3 passes (ASTM method D-1533);
• Removes Particulate Matter to 5 microns as standard or down to 0.3 micron (optional);
• Improves dielectric strength up to 65 kV.

The GlobeCore CMM 0.6 – is designed for removal of free and dissolved water and mechanical contaminants from insulating oil, turbine oil, compressor oil, and lubricating oils.  Its compact design provides excellent mobility with an effective flow rate of 600 liters per hour (L.P.H.)  It is available in trolley or roadworthy trailer mounted, semi-automated, fully automated (PLC controlled) and explosion proof versions. Optional equipment includes moisture probes, flow meter with totalizer and 1 micron fine oil filter.

GLOBECORE CMM 0.6 COMPONENT DESCRIPTION
Vacuum System
Rotary Vane Positive Displacement Pump
Pumping Speed 25 m3/h
Ultimate pressure 0.5 mbar
Inlet and Outlet Oil Pumps
Two Gear pumps with power consumption of 1.1 kW and capacity of 0.8 m3/h is  utilized to draw oil in and out of the vacuum system. Electric motors are protected by overloads.

Vacuum Chamber and Oil Heater
The Vacuum Chamber has an oil sprayer, provided to maximize exposure of oil to the effects of vacuum.
A Coalescer Filter is installed between the Vacuum Chamber and the Vacuum Pump to ensure that no oil is drawn into the Vacuum Pump.
15 kW Oil Heater with a low watt density heating elements (1.2 W/cm2) comes complete with thermometer and thermostat.  An Optional heater can be controlled by an electronic temperature controller or PLC.

Filters
A Mesh Strainer is provided to remove large particles that could cause damage to the Inlet Pump.  A Coarse Filter for particles larger than 5 microns is installed at the entry port to the Vacuum Chamber.  Oil then receives its final treatment by passing through the Fine Filter designed to remove 99.9% of particles larger than 2 microns or with an optional 1 micron capability.

Instrumentation and Controls
The Control Panel is a dust proof enclosure to IP 54 and features the following elements:
Manometers – are installed to monitor the state of Coarse and Fine Filters.
A Vacuum Meter is provided to monitor vacuum level in the chamber.
A Temperature controller (optional) – receives  a data input from the temperature sensor and is  connected to a control element of the heater.
Power and Heating Indicators and Switches, Oil Pump Switches and PLC with Mnemonic Diagram (optional).
Emergency Stop Button – is provided for safe shut down of the plant in case of emergency.

OPTIONAL EQUIPMENT
Moisture Probe
The transmitter provides on-line transformer oil measurement of both the temperature and moisture content.  The unit comes complete with a display showing the level of moisture in a “ppm” readout.
Flowmeter
The “Influx Flotrack” flow meter gives a reading in m3/h and a totalizer shows the amount of total flow that has passed through the meter in a given amount of time.
