COMPONENTS DESCRIPTION:
I. VACUUM SYSTEM
CMM (UVM) 4 has the following vacuum facilities:
1. “GlobeCore” Rotary Vane Positive Displacement Pump
Pumping Speed 100 m3/h
Ultimate Pressure 0.5 mbar
2. “Globe Corel” Vacuum Booster
Pumping Speed 270 m3/h
Ultimate Pressure 0.01 mbar

3. II. VACUUM CHAMBER
This Oil Purification plant has horizontal Vacuum Column with Coalescers.
Vacuum Chamber Vessels and all internal parts are made of carbon steel and
feature Coalescers, Sight Glass, Oil Level Controller and Vacuum Gauge.
Vacuum Chamber’s rigid design makes it suitable for stationary and mobile
installation. Appropriate flexible connections are provided to the outlet pump and
inlet pump to minimize negative effect of vibration during plant operation and
transportation.
Vacuum Chamber
1–Oil Inlet
2–Vacuum Pump Connection
3–Coalescers
4–Oil Outlet
5–Level Sensor
6–Sight Glass
Coalescers - four built-in coalescers are provided for the maximum exposure of
oil to the effect of vacuum. Due to reduced pressure dissolved water and gases
are vaporised through secondary chamber and filter into atmosphere.
Secondary Chamber (Oil Trap) - serves as safety feature to ensure that no oil
is pulled into the vacuum pump. It is equipped with oil level sensor which will
activate the alarm in case of oil presence.
Oil Level Controller - consists of three capacitive probes provided to maintain
required level of oil in the Vacuum Chamber.
Vacuum Gauge - is provided to monitor Vacuum level in the Vacuum
Chamber. Vacuum gauge will be absolute type with display in mbar.
Vacuum ports – vacuum connection is provided to pull vacuum on transformer.
Sampling Ports – inlet and outlet oil ports are provided for incoming and
processed oil.

4. III. OIL HEATER
The electric oil heating facility is provided in 2 stages offering a total of 55 kW
of power. A low watt density encapsulated heating elements (1.2 W/cm²) are
used to prevent heat degradation of oil. The Heater is controlled by electronic
temperature controller.
IV. INLET AND OUTLET OIL PUMPS
Inlet Oil Pump: “Calpeda” Centrifugal Pump with power consumption of 1.5
kW and maximum capacity of 7 m³/h.
Outlet Oil Pump: “Calpeda” Centrifugal Pump with power consumption of 2.2
kW and maximum capacity of 7 m³/h.
V. FILTERS
A 90 micron Mesh Strainer is provided to remove large particles that could
cause damage to the Inlet Pump. 25 micron Coarse Filter is installed on entry
to the Vacuum Chamber. Oil receives its final treatment by passing through the
5 micron Fine Filter designed to remove 99.9% of particles larger than 5
microns.

5. VI. ALARMS AND INTERLOCKS
GlobeCore’s CMM plants feature the following safety devises which ensure
simple and reliable operation and will safely shut down the system in case of any
alarm situation:
High Level Alarm - will alert plant’s operator by activating sound and light
alarms and shut down the system safely should high level of oil persist.
Low Level Alarm – interlocked with the inlet pump low level alarm will safely
shut down the plant in case of insufficient oil level.
Flow Sensor - only activates the Heater when oil flow is detected.
Overloads – all motors are protected by overloads.
Alarms – sound and light alarm with silence button will alert plant’s operator of
any emergency situations.
VII. INSTRUMENTATION AND CONTROLS
Control panel is a dust proof enclosure (protection class IP 54) featuring the
following elements:
Vacuum meters - monitor vacuum level in the vacuum chamber and secondary
chamber.
Manometers - are installed to monitor the state of Coarse and Fine Filters and oil
pressure on outlet.
Temperature controller – takes an input from temperature sensor and connected
to a control element of the heater. Measuring and control parameters are pre-set
by the manufacturer.
Power and Heating Indicators and Switches, Inlet and Outlet Oil Pumps
Switches, Vacuum Pump and Vacuum Booster switches
Emergency Stop Button – is provided for safe shut down of the plant in case of
emergency.

OPERATIONAL PRINCIPLE
The unit can be operated in the following modes:
- oil heating and filtration
- filtration, heating and thermo-vacuum oil purification
- vacuummising of a transformer tank
Heating and filtration mode: oil goes through the unit via valve K1, mesh filter РF,
valve K10 pumped by oil pump P1 through the oil heater MN, cartridge filter F1, ball
valve K2, K5 to the unit output.

7. Filtration, heating and thermo-vacuum oil purification: transformer oil is fed
through valve K1, mesh filter РF, valve K10, oil pump P1 through oil heater MN,
cartridge filter F1. Heated to temperature (50…60ºС) and purified from mechanical
impurities oil is fed through ball valve K3, comes into vacuum column CV, passes
through coalescers. Vacuum in the chamber is created by vacuum pump VP. Vacuum
value in the chamber is maintained by means of the valve К11 and controlled by
vacuum gage VM. Air is supplied into chamber through moisture eliminator FV,
ascending air carries out gases and water vapour from the oil surface and in this way
the oil is dried. Wet air is subsequently removed into atmosphere via vacuum pump.
Oil from the column is fed to the transformer by oil pump P2 through valves K8, K9,
cartridge filter F2, return valve SV and ball valve K5 into the tank for clean oil. The K3
valve establishes necessary flow rate. The vacuum in the column is created by vacuum
pump VP1 and maintained at 0,8 bar during operation.
Vacuumizing of transformer: is carried out by pump VP through valve for
vacuumizing of the external equipment.
