Deep vacuum systems
UVM-10M, UVM-6 systems are used for thermal
vacuum degasification, azotizing, drying, heating and
purification of transformer, cable, turbine and other
oils for removal of gases, free and soluble water and
particulate matter. The system is applied while
installation, repair and operating of oil-filled highvoltage equipment up to 1150 kV (power
transformers, high-voltage switches etc.) as well as
turbines. The system can be exploited for heating of
oil-filled units with hot oil and for vacuumizing of
power transformers. The system consists of two
isolated sections: the oil section and vacuum section
interconnected with a vacuum conductor.
The oil section is intended for degasification and removal of mechanical impurities, azotizing, heating and pumping of oil. The oil
section corresponds to a metallic, heat-insulated box wherein are located a vacuum column, oil heater-filter, receiver, oil inlet and
output pumps, absorptiometer with a vacuum pump, fine filter and pre-filter, control cabinet, stop and control valves, oil pipelines
and vacuum conductor. The absorptiometer allows to perform a rapid analysis of residual gas content in the oil. The section
operational parameters are controlled by temperature regulators with a sensor, vacuum control device with lamps, pressure-andvacuum gages. Electrical circuit provides for switching off the system in case of the oil flow’s absence, oil heater’s overheating
(with providing of a sound signal), short circuit protection, improper phase interlacing prevention, phase breakage protection.
Processed oil’s temperature is maintained automatically.
UVM-10M
The vacuum section is intended for exhaust of air, non-aggressive gases and vapor reviously cleaned of condensed moisture and
particulates out of insulated vacuum units, particularly out of the vacuum column of the oil box. The vacuum section corresponds
to a metallic box with a concreted bottom wherein are located vacuum units, an oil pump, axial blower, heating element, a tank
with heaters, control cabinet, vacuum connector with a non-return valve, compensator, fly gate, vacuum meters. The vacuum
section’s parameters are controlled by the vacuum meters, temperature regulators. The electric circuit is protected in the same
manner as in the oil section.
There is a possibility provided for the oil’s process along closed cycle. The three-stage filtration system enables to process a good
amount of oil until scheduled removal of filter elements. The oil degasification is put into effect in the thermal vacuum manner along
with spraying in the vacuum column.
The oil is directed by the oil pump into the oil heater, after being heated and clarified from particulates the oil moves to the vacuum
column wherein it is sprayed and trickles down along the inlet fittings. Tickling along the inlet fittings the oil forms a thin tape,
owing to this, gases and moisture intensely vaporize. The vacuum in the column is maintained with vacuum pumps which provide
removal of gases and moisture through the receiver. The degasified oil is directed through the fine filter system into the

Oil regeneration system
UVM-R-0.7
Application
The UVM-R-0.7 transformer oil regeneration system serves for regeneration of insulation
oil to its virgin characteristics. The system also provides filtration, drying, discoloration and
removal of particulate, sludge and other soluble oil decay products. Application of the
system allows acid number of oil to be improved. It is used to regenerate insulating oils in
transformers that are being installed or repaired. It is applicable for high-voltage power
transformers, switches, i.e. high-voltage equipment.
How it works
The working principle of the system is as follows: there are two vessels, one is for oil and
the other is for powder-like matter. As soon as oil and powder have been filled into the
vessels, the oil treatment process takes place. This is one cycle of treatment. The vessel
capacity for oil is 200 lt and for powder is 8 kg which makes up 4% out of amount of oil
(200 lt). In other words average consumption of the powder is 4-6% out of amount of oil to
be treated. If you use in process fuller’s earth you can regenerate this matter.
The powder-like matter is not restorable. However application exactly of this powder makes improving of acid number of oil possible
more than twenty times better unlike Fuller’s Earth. Nevertheless if you always use the Fuller’s Earth it can be applied on the
system UVM-R-0.7 too. It will not violate technological cycle and you will be able to recover fuller’s earth the way it is recovered on
other systems. Be advised that on using of Fuller’s Earth the post treatment parameters may differ from those claimed by us. After
being treated with the powder, the oil goes to filters for further treatment namely to be cleared from mechanical solids. The settled
powder is directed to the pressure filter for expressing the soaked oil out of it, it allows to avoid the unwanted oil loss. That’s why
the use of pressure filter is necessary. After processing the powder is disposed. The pressure filter comes with cost of the system.
UVM-R-0.7 with filter-press
Description
Regeneration of transformer oils is needed when the transformer oil has
deteriorated to a level whereby regular oil purification (cleaning & filtration)
is no longer adequate. The regeneration or reclamation process requires
passing the deteriorated transformer oil through an adsorbent media such as
specifically prepared sorbent powder or fuller’s earth. Sorbent powder’s
consumption in UVM-R-0.7 is ranged between 4% and 6% of the weight of
regenerated oil. One-pass clay load is 50 kg, which enables regeneration of 1
ton of oil. The UVM-R-0.7 system includes oil heater, coarse filter, fine filter,
and oil pump are assembled together in a single unit (Fig.1). A press-filter,
the separate unit (Fig. 2), holds sorbent powder for final processing of oil

The vacuum vessel is a cylindrical chamber which is placed in a casing. There are also electrical heaters to heat oil under
processing in the casing. The vessel is heat-insulated outside. In the upper part of the chamber there an oil sparger is set. The
vacuum vessel is connected with atmosphere through the moisture separating filter and throttle. Rate of exhaustion in the chamber
is regulated by the throttle.
The gear type pumps are equipped with a bypass line which has taps and safety valves on it. The drive mechanism of each pump
is an asynchronous three-phase motor with a squirrel cage rotor (2.2 KW and 1440 rpm).
The vacuum pump is intended for exhaustion in the chamber.
The vacuum pipeline is equipped with a siphon compensator, back-pressure valve, moisture Heater drive circuit is interlocked with
pump drive circuit. In the control cabinet is located magnetic starter, heat regulator supporting set range temperature, indicator
lamp.
How it works
The purification system operates in modes as follows
- filtration mode
- filtration, heating and thermal vacuum purification mode
- degasification mode
page
www.uvm.com.ua
Oil purification systems
page
The filtration mode
Through the input valve and mesh filter the deteriorated oil is sucked by the gear type pump and then through the primary
cartridge filter and three-way valve goes to the processed oil vessel.
Filtration, heating and thermal vacuum purification mode
Through the input valve and mesh filter the deteriorated oil is sucked in by the gear type pump and through the primary filter goes
to the casing of the vacuum vessel. There the oil is heated with the electric heaters up to 60°C and subsequently moves to the
sparger of the vacuum vessel. Vacuum in the vessel is supported by the vacuum pump. Rate of exhaustion in the vessel is
regulated with the throttle and controlled by the vacuumeter. Air gets to the vessel through the moisture separator. Gases and
vapors are carried away off the oil surface with rising stream of air so that the oil becomes dried. Next humid air is taken out
through the moisture separator to atmosphere with the vacuum pump. The gear type pump directs purified oil through the fine filter
and back valve to the purified oil vessel.
Degasification mode
Being sucked by the gear type pump the deteriorated oil moves through the input valve, mesh filter and cartridge filter to the
casing of the vacuum vessel to heated there and be directed to the sparger. As was mentioned above vacuum is supported by the
vacuum pump. In the sparger there occurs separation of gases from the oil. The gases are taken out through the oil separator to
atmosphere by the vacuum pump. Being directed by the gear type pump the degassed oil moves through the fine filter and back
valve to the purified oil vessel.
Design properties:
Small-scale dimensions and weight of the system permit to use it as mobile one with the help of a cart and to treat the oil on-site.
UVM-EP-10-0.6 and UVM-EP-10-4.0 models enjoy explosion proof design (the abbreviation EP stands for explosion proof). Such
construction of the system permits to work in environments with possible risk of explosion.
Note: each model can go with a trailer thus it is available to be applied for on-line activities.

Heating and filtration systems
The UVM-10-0.6, UVM-10-4.0 systems are used for heating and filtration of insulating and
lubricating oil in order to clarify from particulates, soot, free and soluble water, alkali, watersoluble acids. The viscosity of oil is not to exceed 70 cSt at temperature +50°C.
How it works
The pump drives oil in procession through the mesh filter, inlet valve into the heater.
Afterwards warmed up to necessary temperature oil is directed to the pre filter. After
preliminary filtration is over the oil goes to the filter. The purified oil through the connecting
pipe pours off to the vessel (the vessel does not go with the complete set). Condensate
extracted from the oil pours off through the valves.

The UVM-F-0.5(micro) filtration system is a compact free standing off line oil cleaning and
filtration system, capable of removing fine dirt particles and totally removing water. Filter
cartridges are also available for use on water based fluids. To achieve optimum cleanliness,
the contents of each tank should pass through the filter a minimum of 4-5 times. E.g. a 500
liter tank at 40°C will take approx. 4-5 hours to clean.
Note: The above is a guide only and results will depend on the contamination level in each
tank.
