Factory
GlobeCore is a leader in the field of development and implementation of
industrial equipment for reclamation, purification, drying and degassing of
transformer, turbine, industrial, mineral and other oils.
GlobeCore’s regeneration process refines waste oils by removing contaminants,
oxidation products and additives and thereby restoring the oil’s colour and
properties to its original new status.
The equipment is in compliance with all relevant international standards. Quality
control complies with ISO 9001:2001. Certificate No UA.2.039.02021-06

3. 1. General UK Representation by Drallim
The necessity for regular
purification of electrical insulating
fluids has been recognised for a
very long time. Moisture, solids
and gaseous contaminants can
seriously affect the function of
electrical insulating fluids as a
coolant and insulator.
Purifiers are designed to process transformer oil in workshops or in the
field, in storage tanks, drums or directly in transformers.
Purification of oil in transformers can be carried out off-load or on-load
depending on customer’s preference.
For purification of oil in the field, a mobile type purification plant,
mounted on a roadworthy trailer is recommended.

6. 4. Process Description UK Representation by Drallim
Oil is pumped through mesh and coarse filters
into vacuum chamber by oil pump, where it is
heated to operation temperature by oil heater.
In the vacuum chamber, by vacuum distillation,
water, dissolved air and gases and other volatile
contaminants are removed. The processed oil is
returned by discharge pump from the vacuum
chamber to the transformer or storage tank
through the fine filter as purified oil.

8. 6. Instrumentation
UK Representation by Drallim
Instrumentation and electrical controls are located in a
dust proof enclosure. A mimic panel is provided for the
convenience of the operator showing the functions of
the main components of the plant by way of pilot lights.
Purifier systems that are provided with full automation
are also provided with a manual override of various
functions as standard. Even with manual override vital
plant protection such as oil overflow remain operational.
Standard instrumentation and controls comprise of:
Temperature Controller, Vacuum Indicator, Pressure
Gauges,Vacuum Gauge and Level Control, Pump’s
“Start” buttons and Indicating lights.

10. 8. Moisture Measurement
UK Representation by Drallim
The MMT162 incorporates
the latest generation of the
Vaisala HUMICAP®Sensor.
The sensor is developed for
demanding moisture
measurement in liquid
hydrocarbons and has been
successfully used in oil
applications for over a
decade. The sensor’s
excellent chemical tolerance
provides accurate and
reliable measurement over
the measurement range.
