421 The unit can be operated in the following modes
ndash laquoHeating and filtration (HampF) and vacuumizing of external equipment (VAC)raquo
ndash laquoThermovacuum heating (DRY) and degassing (DEG)raquo
422 In oil heating and filtration mode unprocessed oil enters the unit through ball valve MV1
pre-filter MF is supplied by pump P1 through valve MV10 oil heater H cartridge filter F1 electric
valve V2 return valve ВV3 oil meter LC valve MV2 to the outlet of the unit
The oil is filtered and heated in this mode
In this mode the heater and the pump P1 can be controlled Control of the P2 pump is
locked
It is also possible to control vacuum pumps VP1 and VP2 for vacuumizing external
equipment
Vacuumizing of a transformer is performed by pumps VP1 and VP2 through the vacuumizing
connector
423 Transformer oil is degassed by heat and vacuum
13
CMM-00000GU CMM-00000GU
In the thermovacuum drying and degassing mode the unitrsquos inlet is connected to the oil container
and the outlet is connected to
- transformer tank gate valve if the pressure in the transformer during filling is above 267 Pa
- transformer top gate if the pressure in the transformer is below 267 Pa
Transformer oil is pumped by P1 through valve MV1 and pre-filter MF the valve MV10 oil heater
H filter F1 electric valve V1 to vacuum chamber VC Hot oil (55hellip60ordmС) with particulate matter
removed passes through the activator filter (sprayer) in the chamber The vacuum in the chamber is
maintained by vacuum pumps VP1 VP2 The vacuum in the chamber is controlled by Pirani device with
DG1 sensor
Moist air is then expelled into the atmosphere through valve MV3 and oil trap OT by pumps VP1
and VP2
The oil from the chamber is pumped by pump P2 through valve MV9 filter F2 return valve ВV2
and ball valve MV2 and oil meter LC into the transformer
The vacuum in the chamber is maintained by the vacuum pumps Residual pressure (up to 267 Pa)
created in the vacuum chamber allows to achieve the required oil quality
When the oil passes through the chamber vacuum causes moisture and air to be removed from
the oil
In this mode the oil is filtered dried and degassed
To eliminate the chance of supplying poorly processed oil in the initial period of operation the unit
has a warm-up mode In this mode the vacuum chamber is filled with transformer oil then the oil is
heated by the hot oil which circulates in the following order
- vacuum chamber VС
- oil pump P2
- ball valve MV9
- filter F2
- ball valve MV4
- oil heater H
- filter F1
- electric valve V1
During circulation it is possible that the output pump stops due to oil level falling below the low
level sensor To avoid this fill the unit with oil to the level higher than the low level sensor
To prevent oil (or foam) from entering the vacuum system the vacuum chamber is equipped with a
foam sensor LS4 which opens valve V3 to reduce foam level Also oil trap OT is equipped with a level
sensor LS5 When oil or foam enters the vacuum system and activates LS5 an alarm is counded the
input and output pumps P1 and P2 stop as well as vacuum pumps VP1 VP2 Electromagnetic valve V1
stops the flow of oil into the vacuum chamber Electromagnetic valve V3 opens to facilitate foam
removal
If the unit loses power supply the electromagnetic valve V1 stops oil input into the vacuum
chamber it also closes in case of overheating of oil in the oil heater

421 The unit can be operated in the following modes
ndash laquoHeating and filtration (HampF) and vacuumizing of external equipment (VAC)raquo
ndash laquoThermovacuum heating (DRY) and degassing (DEG)raquo
422 In oil heating and filtration mode unprocessed oil enters the unit through ball valve MV1
pre-filter MF is supplied by pump P1 through valve MV10 oil heater H cartridge filter F1 electric
valve V2 return valve ВV3 oil meter LC valve MV2 to the outlet of the unit
The oil is filtered and heated in this mode
In this mode the heater and the pump P1 can be controlled Control of the P2 pump is
locked
It is also possible to control vacuum pumps VP1 and VP2 for vacuumizing external
equipment
Vacuumizing of a transformer is performed by pumps VP1 and VP2 through the vacuumizing
connector
423 Transformer oil is degassed by heat and vacuum
13
CMM-00000GU CMM-00000GU
In the thermovacuum drying and degassing mode the unitrsquos inlet is connected to the oil container
and the outlet is connected to
- transformer tank gate valve if the pressure in the transformer during filling is above 267 Pa
- transformer top gate if the pressure in the transformer is below 267 Pa
Transformer oil is pumped by P1 through valve MV1 and pre-filter MF the valve MV10 oil heater
H filter F1 electric valve V1 to vacuum chamber VC Hot oil (55hellip60ordmС) with particulate matter
removed passes through the activator filter (sprayer) in the chamber The vacuum in the chamber is
maintained by vacuum pumps VP1 VP2 The vacuum in the chamber is controlled by Pirani device with
DG1 sensor
Moist air is then expelled into the atmosphere through valve MV3 and oil trap OT by pumps VP1
and VP2
The oil from the chamber is pumped by pump P2 through valve MV9 filter F2 return valve ВV2
and ball valve MV2 and oil meter LC into the transformer
The vacuum in the chamber is maintained by the vacuum pumps Residual pressure (up to 267 Pa)
created in the vacuum chamber allows to achieve the required oil quality
When the oil passes through the chamber vacuum causes moisture and air to be removed from
the oil
In this mode the oil is filtered dried and degassed
To eliminate the chance of supplying poorly processed oil in the initial period of operation the unit
has a warm-up mode In this mode the vacuum chamber is filled with transformer oil then the oil is
heated by the hot oil which circulates in the following order
- vacuum chamber VС
- oil pump P2
- ball valve MV9
- filter F2
- ball valve MV4
- oil heater H
- filter F1
- electric valve V1
During circulation it is possible that the output pump stops due to oil level falling below the low
level sensor To avoid this fill the unit with oil to the level higher than the low level sensor
To prevent oil (or foam) from entering the vacuum system the vacuum chamber is equipped with a
foam sensor LS4 which opens valve V3 to reduce foam level Also oil trap OT is equipped with a level
sensor LS5 When oil or foam enters the vacuum system and activates LS5 an alarm is counded the
input and output pumps P1 and P2 stop as well as vacuum pumps VP1 VP2 Electromagnetic valve V1
stops the flow of oil into the vacuum chamber Electromagnetic valve V3 opens to facilitate foam
removal
If the unit loses power supply the electromagnetic valve V1 stops oil input into the vacuum
chamber it also closes in case of overheating of oil in the oil heater

421 The unit can be operated in the following modes
ndash laquoHeating and filtration (HampF) and vacuumizing of external equipment (VAC)raquo
ndash laquoThermovacuum heating (DRY) and degassing (DEG)raquo
422 In oil heating and filtration mode unprocessed oil enters the unit through ball valve MV1
pre-filter MF is supplied by pump P1 through valve MV10 oil heater H cartridge filter F1 electric
valve V2 return valve ВV3 oil meter LC valve MV2 to the outlet of the unit
The oil is filtered and heated in this mode
In this mode the heater and the pump P1 can be controlled Control of the P2 pump is
locked
It is also possible to control vacuum pumps VP1 and VP2 for vacuumizing external
equipment
Vacuumizing of a transformer is performed by pumps VP1 and VP2 through the vacuumizing
connector
423 Transformer oil is degassed by heat and vacuum
13
CMM-00000GU CMM-00000GU
In the thermovacuum drying and degassing mode the unitrsquos inlet is connected to the oil container
and the outlet is connected to
- transformer tank gate valve if the pressure in the transformer during filling is above 267 Pa
- transformer top gate if the pressure in the transformer is below 267 Pa
Transformer oil is pumped by P1 through valve MV1 and pre-filter MF the valve MV10 oil heater
H filter F1 electric valve V1 to vacuum chamber VC Hot oil (55hellip60ordmС) with particulate matter
removed passes through the activator filter (sprayer) in the chamber The vacuum in the chamber is
maintained by vacuum pumps VP1 VP2 The vacuum in the chamber is controlled by Pirani device with
DG1 sensor
Moist air is then expelled into the atmosphere through valve MV3 and oil trap OT by pumps VP1
and VP2
The oil from the chamber is pumped by pump P2 through valve MV9 filter F2 return valve ВV2
and ball valve MV2 and oil meter LC into the transformer
The vacuum in the chamber is maintained by the vacuum pumps Residual pressure (up to 267 Pa)
created in the vacuum chamber allows to achieve the required oil quality
When the oil passes through the chamber vacuum causes moisture and air to be removed from
the oil
In this mode the oil is filtered dried and degassed
To eliminate the chance of supplying poorly processed oil in the initial period of operation the unit
has a warm-up mode In this mode the vacuum chamber is filled with transformer oil then the oil is
heated by the hot oil which circulates in the following order
- vacuum chamber VС
- oil pump P2
- ball valve MV9
- filter F2
- ball valve MV4
- oil heater H
- filter F1
- electric valve V1
During circulation it is possible that the output pump stops due to oil level falling below the low
level sensor To avoid this fill the unit with oil to the level higher than the low level sensor
To prevent oil (or foam) from entering the vacuum system the vacuum chamber is equipped with a
foam sensor LS4 which opens valve V3 to reduce foam level Also oil trap OT is equipped with a level
sensor LS5 When oil or foam enters the vacuum system and activates LS5 an alarm is counded the
input and output pumps P1 and P2 stop as well as vacuum pumps VP1 VP2 Electromagnetic valve V1
stops the flow of oil into the vacuum chamber Electromagnetic valve V3 opens to facilitate foam
removal
If the unit loses power supply the electromagnetic valve V1 stops oil input into the vacuum
chamber it also closes in case of overheating of oil in the oil heater

421 The unit can be operated in the following modes
ndash laquoHeating and filtration (HampF) and vacuumizing of external equipment (VAC)raquo
ndash laquoThermovacuum heating (DRY) and degassing (DEG)raquo
422 In oil heating and filtration mode unprocessed oil enters the unit through ball valve MV1
pre-filter MF is supplied by pump P1 through valve MV10 oil heater H cartridge filter F1 electric
valve V2 return valve ВV3 oil meter LC valve MV2 to the outlet of the unit
The oil is filtered and heated in this mode
In this mode the heater and the pump P1 can be controlled Control of the P2 pump is
locked
It is also possible to control vacuum pumps VP1 and VP2 for vacuumizing external
equipment
Vacuumizing of a transformer is performed by pumps VP1 and VP2 through the vacuumizing
connector
423 Transformer oil is degassed by heat and vacuum
13
CMM-00000GU CMM-00000GU
In the thermovacuum drying and degassing mode the unitrsquos inlet is connected to the oil container
and the outlet is connected to
- transformer tank gate valve if the pressure in the transformer during filling is above 267 Pa
- transformer top gate if the pressure in the transformer is below 267 Pa
Transformer oil is pumped by P1 through valve MV1 and pre-filter MF the valve MV10 oil heater
H filter F1 electric valve V1 to vacuum chamber VC Hot oil (55hellip60ordmС) with particulate matter
removed passes through the activator filter (sprayer) in the chamber The vacuum in the chamber is
maintained by vacuum pumps VP1 VP2 The vacuum in the chamber is controlled by Pirani device with
DG1 sensor
Moist air is then expelled into the atmosphere through valve MV3 and oil trap OT by pumps VP1
and VP2
The oil from the chamber is pumped by pump P2 through valve MV9 filter F2 return valve ВV2
and ball valve MV2 and oil meter LC into the transformer
The vacuum in the chamber is maintained by the vacuum pumps Residual pressure (up to 267 Pa)
created in the vacuum chamber allows to achieve the required oil quality
When the oil passes through the chamber vacuum causes moisture and air to be removed from
the oil
In this mode the oil is filtered dried and degassed
To eliminate the chance of supplying poorly processed oil in the initial period of operation the unit
has a warm-up mode In this mode the vacuum chamber is filled with transformer oil then the oil is
heated by the hot oil which circulates in the following order
- vacuum chamber VС
- oil pump P2
- ball valve MV9
- filter F2
- ball valve MV4
- oil heater H
- filter F1
- electric valve V1
During circulation it is possible that the output pump stops due to oil level falling below the low
level sensor To avoid this fill the unit with oil to the level higher than the low level sensor
To prevent oil (or foam) from entering the vacuum system the vacuum chamber is equipped with a
foam sensor LS4 which opens valve V3 to reduce foam level Also oil trap OT is equipped with a level
sensor LS5 When oil or foam enters the vacuum system and activates LS5 an alarm is counded the
input and output pumps P1 and P2 stop as well as vacuum pumps VP1 VP2 Electromagnetic valve V1
stops the flow of oil into the vacuum chamber Electromagnetic valve V3 opens to facilitate foam
removal
If the unit loses power supply the electromagnetic valve V1 stops oil input into the vacuum
chamber it also closes in case of overheating of oil in the oil heater

421 The unit can be operated in the following modes
ndash laquoHeating and filtration (HampF) and vacuumizing of external equipment (VAC)raquo
ndash laquoThermovacuum heating (DRY) and degassing (DEG)raquo
422 In oil heating and filtration mode unprocessed oil enters the unit through ball valve MV1
pre-filter MF is supplied by pump P1 through valve MV10 oil heater H cartridge filter F1 electric
valve V2 return valve ВV3 oil meter LC valve MV2 to the outlet of the unit
The oil is filtered and heated in this mode
In this mode the heater and the pump P1 can be controlled Control of the P2 pump is
locked
It is also possible to control vacuum pumps VP1 and VP2 for vacuumizing external
equipment
Vacuumizing of a transformer is performed by pumps VP1 and VP2 through the vacuumizing
connector
423 Transformer oil is degassed by heat and vacuum
13
CMM-00000GU CMM-00000GU
In the thermovacuum drying and degassing mode the unitrsquos inlet is connected to the oil container
and the outlet is connected to
- transformer tank gate valve if the pressure in the transformer during filling is above 267 Pa
- transformer top gate if the pressure in the transformer is below 267 Pa
Transformer oil is pumped by P1 through valve MV1 and pre-filter MF the valve MV10 oil heater
H filter F1 electric valve V1 to vacuum chamber VC Hot oil (55hellip60ordmС) with particulate matter
removed passes through the activator filter (sprayer) in the chamber The vacuum in the chamber is
maintained by vacuum pumps VP1 VP2 The vacuum in the chamber is controlled by Pirani device with
DG1 sensor
Moist air is then expelled into the atmosphere through valve MV3 and oil trap OT by pumps VP1
and VP2
The oil from the chamber is pumped by pump P2 through valve MV9 filter F2 return valve ВV2
and ball valve MV2 and oil meter LC into the transformer
The vacuum in the chamber is maintained by the vacuum pumps Residual pressure (up to 267 Pa)
created in the vacuum chamber allows to achieve the required oil quality
When the oil passes through the chamber vacuum causes moisture and air to be removed from
the oil
In this mode the oil is filtered dried and degassed
To eliminate the chance of supplying poorly processed oil in the initial period of operation the unit
has a warm-up mode In this mode the vacuum chamber is filled with transformer oil then the oil is
heated by the hot oil which circulates in the following order
- vacuum chamber VС
- oil pump P2
- ball valve MV9
- filter F2
- ball valve MV4
- oil heater H
- filter F1
- electric valve V1
During circulation it is possible that the output pump stops due to oil level falling below the low
level sensor To avoid this fill the unit with oil to the level higher than the low level sensor
To prevent oil (or foam) from entering the vacuum system the vacuum chamber is equipped with a
foam sensor LS4 which opens valve V3 to reduce foam level Also oil trap OT is equipped with a level
sensor LS5 When oil or foam enters the vacuum system and activates LS5 an alarm is counded the
input and output pumps P1 and P2 stop as well as vacuum pumps VP1 VP2 Electromagnetic valve V1
stops the flow of oil into the vacuum chamber Electromagnetic valve V3 opens to facilitate foam
removal
If the unit loses power supply the electromagnetic valve V1 stops oil input into the vacuum
chamber it also closes in case of overheating of oil in the oil heater

DG1 sensor
Moist air is then expelled into the atmosphere through valve MV3 and oil trap OT by pumps VP1
and VP2
The oil from the chamber is pumped by pump P2 through valve MV9 filter F2 return valve ВV2
and ball valve MV2 and oil meter LC into the transformer
The vacuum in the chamber is maintained by the vacuum pumps Residual pressure (up to 267 Pa)
created in the vacuum chamber allows to achieve the required oil quality
When the oil passes through the chamber vacuum causes moisture and air to be removed from
the oil
In this mode the oil is filtered dried and degassed
To eliminate the chance of supplying poorly processed oil in the initial period of operation the unit
has a warm-up mode In this mode the vacuum chamber is filled with transformer oil then the oil is
heated by the hot oil which circulates in the following order
- vacuum chamber VС
- oil pump P2
- ball valve MV9
- filter F2
- ball valve MV4
- oil heater H
- filter F1
- electric valve V1
During circulation it is possible that the output pump stops due to oil level falling below the low
level sensor To avoid this fill the unit with oil to the level higher than the low level sensor
To prevent oil (or foam) from entering the vacuum system the vacuum chamber is equipped with a
foam sensor LS4 which opens valve V3 to reduce foam level Also oil trap OT is equipped with a level
sensor LS5 When oil or foam enters the vacuum system and activates LS5 an alarm is counded the
input and output pumps P1 and P2 stop as well as vacuum pumps VP1 VP2 Electromagnetic valve V1
stops the flow of oil into the vacuum chamber Electromagnetic valve V3 opens to facilitate foam
removal
If the unit loses power supply the electromagnetic valve V1 stops oil input into the vacuum
chamber it also closes in case of overheating of oil in the oil heater

421 The unit can be operated in the following modes
ndash laquoHeating and filtration (HampF) and vacuumizing of external equipment (VAC)raquo
ndash laquoThermovacuum heating (DRY) and degassing (DEG)raquo
422 In oil heating and filtration mode unprocessed oil enters the unit through ball valve MV1
pre-filter MF is supplied by pump P1 through valve MV10 oil heater H cartridge filter F1 electric
valve V2 return valve ВV3 oil meter LC valve MV2 to the outlet of the unit
The oil is filtered and heated in this mode
In this mode the heater and the pump P1 can be controlled Control of the P2 pump is
locked
It is also possible to control vacuum pumps VP1 and VP2 for vacuumizing external
equipment
Vacuumizing of a transformer is performed by pumps VP1 and VP2 through the vacuumizing
connector
423 Transformer oil is degassed by heat and vacuum
13
CMM-00000GU CMM-00000GU
In the thermovacuum drying and degassing mode the unitrsquos inlet is connected to the oil container
and the outlet is connected to
- transformer tank gate valve if the pressure in the transformer during filling is above 267 Pa
- transformer top gate if the pressure in the transformer is below 267 Pa
Transformer oil is pumped by P1 through valve MV1 and pre-filter MF the valve MV10 oil heater
H filter F1 electric valve V1 to vacuum chamber VC Hot oil (55hellip60ordmС) with particulate matter
removed passes through the activator filter (sprayer) in the chamber The vacuum in the chamber is
maintained by vacuum pumps VP1 VP2 The vacuum in the chamber is controlled by Pirani device with
DG1 sensor
Moist air is then expelled into the atmosphere through valve MV3 and oil trap OT by pumps VP1
and VP2
The oil from the chamber is pumped by pump P2 through valve MV9 filter F2 return valve ВV2
and ball valve MV2 and oil meter LC into the transformer
The vacuum in the chamber is maintained by the vacuum pumps Residual pressure (up to 267 Pa)
created in the vacuum chamber allows to achieve the required oil quality
When the oil passes through the chamber vacuum causes moisture and air to be removed from
the oil
In this mode the oil is filtered dried and degassed
To eliminate the chance of supplying poorly processed oil in the initial period of operation the unit
has a warm-up mode In this mode the vacuum chamber is filled with transformer oil then the oil is
heated by the hot oil which circulates in the following order
- vacuum chamber VС
- oil pump P2
- ball valve MV9
- filter F2
- ball valve MV4
- oil heater H
- filter F1
- electric valve V1
During circulation it is possible that the output pump stops due to oil level falling below the low
level sensor To avoid this fill the unit with oil to the level higher than the low level sensor
To prevent oil (or foam) from entering the vacuum system the vacuum chamber is equipped with a
foam sensor LS4 which opens valve V3 to reduce foam level Also oil trap OT is equipped with a level
sensor LS5 When oil or foam enters the vacuum system and activates LS5 an alarm is counded the
input and output pumps P1 and P2 stop as well as vacuum pumps VP1 VP2 Electromagnetic valve V1
stops the flow of oil into the vacuum chamber Electromagnetic valve V3 opens to facilitate foam
removal
If the unit loses power supply the electromagnetic valve V1 stops oil input into the vacuum
chamber it also closes in case of overheating of oil in the oil heater

421 The unit can be operated in the following modes
ndash laquoHeating and filtration (HampF) and vacuumizing of external equipment (VAC)raquo
ndash laquoThermovacuum heating (DRY) and degassing (DEG)raquo
422 In oil heating and filtration mode unprocessed oil enters the unit through ball valve MV1
pre-filter MF is supplied by pump P1 through valve MV10 oil heater H cartridge filter F1 electric
valve V2 return valve ВV3 oil meter LC valve MV2 to the outlet of the unit
The oil is filtered and heated in this mode
In this mode the heater and the pump P1 can be controlled Control of the P2 pump is
locked
It is also possible to control vacuum pumps VP1 and VP2 for vacuumizing external
equipment
Vacuumizing of a transformer is performed by pumps VP1 and VP2 through the vacuumizing
connector
423 Transformer oil is degassed by heat and vacuum
13
CMM-00000GU CMM-00000GU
In the thermovacuum drying and degassing mode the unitrsquos inlet is connected to the oil container
and the outlet is connected to
- transformer tank gate valve if the pressure in the transformer during filling is above 267 Pa
- transformer top gate if the pressure in the transformer is below 267 Pa
Transformer oil is pumped by P1 through valve MV1 and pre-filter MF the valve MV10 oil heater
H filter F1 electric valve V1 to vacuum chamber VC Hot oil (55hellip60ordmС) with particulate matter
removed passes through the activator filter (sprayer) in the chamber The vacuum in the chamber is
maintained by vacuum pumps VP1 VP2 The vacuum in the chamber is controlled by Pirani device with
DG1 sensor
Moist air is then expelled into the atmosphere through valve MV3 and oil trap OT by pumps VP1
and VP2
The oil from the chamber is pumped by pump P2 through valve MV9 filter F2 return valve ВV2
and ball valve MV2 and oil meter LC into the transformer
The vacuum in the chamber is maintained by the vacuum pumps Residual pressure (up to 267 Pa)
created in the vacuum chamber allows to achieve the required oil quality
When the oil passes through the chamber vacuum causes moisture and air to be removed from
the oil
In this mode the oil is filtered dried and degassed
To eliminate the chance of supplying poorly processed oil in the initial period of operation the unit
has a warm-up mode In this mode the vacuum chamber is filled with transformer oil then the oil is
heated by the hot oil which circulates in the following order
- vacuum chamber VС
- oil pump P2
- ball valve MV9
- filter F2
- ball valve MV4
- oil heater H
- filter F1
- electric valve V1
During circulation it is possible that the output pump stops due to oil level falling below the low
level sensor To avoid this fill the unit with oil to the level higher than the low level sensor
To prevent oil (or foam) from entering the vacuum system the vacuum chamber is equipped with a
foam sensor LS4 which opens valve V3 to reduce foam level Also oil trap OT is equipped with a level
sensor LS5 When oil or foam enters the vacuum system and activates LS5 an alarm is counded the
input and output pumps P1 and P2 stop as well as vacuum pumps VP1 VP2 Electromagnetic valve V1
stops the flow of oil into the vacuum chamber Electromagnetic valve V3 opens to facilitate foam
removal
If the unit loses power supply the electromagnetic valve V1 stops oil input into the vacuum
chamber it also closes in case of overheating of oil in the oil heater

421 The unit can be operated in the following modes
ndash laquoHeating and filtration (HampF) and vacuumizing of external equipment (VAC)raquo
ndash laquoThermovacuum heating (DRY) and degassing (DEG)raquo
422 In oil heating and filtration mode unprocessed oil enters the unit through ball valve MV1
pre-filter MF is supplied by pump P1 through valve MV10 oil heater H cartridge filter F1 electric
valve V2 return valve ВV3 oil meter LC valve MV2 to the outlet of the unit
The oil is filtered and heated in this mode
In this mode the heater and the pump P1 can be controlled Control of the P2 pump is
locked
It is also possible to control vacuum pumps VP1 and VP2 for vacuumizing external
equipment
Vacuumizing of a transformer is performed by pumps VP1 and VP2 through the vacuumizing
connector
423 Transformer oil is degassed by heat and vacuum
13
CMM-00000GU CMM-00000GU
In the thermovacuum drying and degassing mode the unitrsquos inlet is connected to the oil container
and the outlet is connected to
- transformer tank gate valve if the pressure in the transformer during filling is above 267 Pa
- transformer top gate if the pressure in the transformer is below 267 Pa
Transformer oil is pumped by P1 through valve MV1 and pre-filter MF the valve MV10 oil heater
H filter F1 electric valve V1 to vacuum chamber VC Hot oil (55hellip60ordmС) with particulate matter
removed passes through the activator filter (sprayer) in the chamber The vacuum in the chamber is
maintained by vacuum pumps VP1 VP2 The vacuum in the chamber is controlled by Pirani device with
DG1 sensor
Moist air is then expelled into the atmosphere through valve MV3 and oil trap OT by pumps VP1
and VP2
The oil from the chamber is pumped by pump P2 through valve MV9 filter F2 return valve ВV2
and ball valve MV2 and oil meter LC into the transformer
The vacuum in the chamber is maintained by the vacuum pumps Residual pressure (up to 267 Pa)
created in the vacuum chamber allows to achieve the required oil quality
When the oil passes through the chamber vacuum causes moisture and air to be removed from
the oil
In this mode the oil is filtered dried and degassed
To eliminate the chance of supplying poorly processed oil in the initial period of operation the unit
has a warm-up mode In this mode the vacuum chamber is filled with transformer oil then the oil is
heated by the hot oil which circulates in the following order
- vacuum chamber VС
- oil pump P2
- ball valve MV9
- filter F2
- ball valve MV4
- oil heater H
- filter F1
- electric valve V1
During circulation it is possible that the output pump stops due to oil level falling below the low
level sensor To avoid this fill the unit with oil to the level higher than the low level sensor
To prevent oil (or foam) from entering the vacuum system the vacuum chamber is equipped with a
foam sensor LS4 which opens valve V3 to reduce foam level Also oil trap OT is equipped with a level
sensor LS5 When oil or foam enters the vacuum system and activates LS5 an alarm is counded the
input and output pumps P1 and P2 stop as well as vacuum pumps VP1 VP2 Electromagnetic valve V1
stops the flow of oil into the vacuum chamber Electromagnetic valve V3 opens to facilitate foam
removal
If the unit loses power supply the electromagnetic valve V1 stops oil input into the vacuum
chamber it also closes in case of overheating of oil in the oil heater

421 The unit can be operated in the following modes
ndash laquoHeating and filtration (HampF) and vacuumizing of external equipment (VAC)raquo
ndash laquoThermovacuum heating (DRY) and degassing (DEG)raquo
422 In oil heating and filtration mode unprocessed oil enters the unit through ball valve MV1
pre-filter MF is supplied by pump P1 through valve MV10 oil heater H cartridge filter F1 electric
valve V2 return valve ВV3 oil meter LC valve MV2 to the outlet of the unit
The oil is filtered and heated in this mode
In this mode the heater and the pump P1 can be controlled Control of the P2 pump is
locked
It is also possible to control vacuum pumps VP1 and VP2 for vacuumizing external
equipment
Vacuumizing of a transformer is performed by pumps VP1 and VP2 through the vacuumizing
connector
423 Transformer oil is degassed by heat and vacuum
13
CMM-00000GU CMM-00000GU
In the thermovacuum drying and degassing mode the unitrsquos inlet is connected to the oil container
and the outlet is connected to
- transformer tank gate valve if the pressure in the transformer during filling is above 267 Pa
- transformer top gate if the pressure in the transformer is below 267 Pa
Transformer oil is pumped by P1 through valve MV1 and pre-filter MF the valve MV10 oil heater
H filter F1 electric valve V1 to vacuum chamber VC Hot oil (55hellip60ordmС) with particulate matter
removed passes through the activator filter (sprayer) in the chamber The vacuum in the chamber is
maintained by vacuum pumps VP1 VP2 The vacuum in the chamber is controlled by Pirani device with
DG1 sensor
Moist air is then expelled into the atmosphere through valve MV3 and oil trap OT by pumps VP1
and VP2
The oil from the chamber is pumped by pump P2 through valve MV9 filter F2 return valve ВV2
and ball valve MV2 and oil meter LC into the transformer
The vacuum in the chamber is maintained by the vacuum pumps Residual pressure (up to 267 Pa)
created in the vacuum chamber allows to achieve the required oil quality
When the oil passes through the chamber vacuum causes moisture and air to be removed from
the oil
In this mode the oil is filtered dried and degassed
To eliminate the chance of supplying poorly processed oil in the initial period of operation the unit
has a warm-up mode In this mode the vacuum chamber is filled with transformer oil then the oil is
heated by the hot oil which circulates in the following order
- vacuum chamber VС
- oil pump P2
- ball valve MV9
- filter F2
- ball valve MV4
- oil heater H
- filter F1
- electric valve V1
During circulation it is possible that the output pump stops due to oil level falling below the low
level sensor To avoid this fill the unit with oil to the level higher than the low level sensor
To prevent oil (or foam) from entering the vacuum system the vacuum chamber is equipped with a
foam sensor LS4 which opens valve V3 to reduce foam level Also oil trap OT is equipped with a level
sensor LS5 When oil or foam enters the vacuum system and activates LS5 an alarm is counded the
input and output pumps P1 and P2 stop as well as vacuum pumps VP1 VP2 Electromagnetic valve V1
stops the flow of oil into the vacuum chamber Electromagnetic valve V3 opens to facilitate foam
removal
If the unit loses power supply the electromagnetic valve V1 stops oil input into the vacuum
chamber it also closes in case of overheating of oil in the oil heater

The vacuum in the chamber is maintained by the vacuum pumps Residual pressure (up to 267 Pa)
created in the vacuum chamber allows to achieve the required oil quality
When the oil passes through the chamber vacuum causes moisture and air to be removed from
the oil
In this mode the oil is filtered dried and degassed
To eliminate the chance of supplying poorly processed oil in the initial period of operation the unit
has a warm-up mode In this mode the vacuum chamber is filled with transformer oil then the oil is
heated by the hot oil which circulates in the following order
- vacuum chamber VС
- oil pump P2
- ball valve MV9
- filter F2
- ball valve MV4
- oil heater H
- filter F1
- electric valve V1
During circulation it is possible that the output pump stops due to oil level falling below the low
level sensor To avoid this fill the unit with oil to the level higher than the low level sensor
To prevent oil (or foam) from entering the vacuum system the vacuum chamber is equipped with a
foam sensor LS4 which opens valve V3 to reduce foam level Also oil trap OT is equipped with a level
sensor LS5 When oil or foam enters the vacuum system and activates LS5 an alarm is counded the
input and output pumps P1 and P2 stop as well as vacuum pumps VP1 VP2 Electromagnetic valve V1
stops the flow of oil into the vacuum chamber Electromagnetic valve V3 opens to facilitate foam
removal
If the unit loses power supply the electromagnetic valve V1 stops oil input into the vacuum
chamber it also closes in case of overheating of oil in the oil heater

421 The unit can be operated in the following modes
ndash laquoHeating and filtration (HampF) and vacuumizing of external equipment (VAC)raquo
ndash laquoThermovacuum heating (DRY) and degassing (DEG)raquo
422 In oil heating and filtration mode unprocessed oil enters the unit through ball valve MV1
pre-filter MF is supplied by pump P1 through valve MV10 oil heater H cartridge filter F1 electric
valve V2 return valve ВV3 oil meter LC valve MV2 to the outlet of the unit
The oil is filtered and heated in this mode
In this mode the heater and the pump P1 can be controlled Control of the P2 pump is
locked
It is also possible to control vacuum pumps VP1 and VP2 for vacuumizing external
equipment
Vacuumizing of a transformer is performed by pumps VP1 and VP2 through the vacuumizing
connector
423 Transformer oil is degassed by heat and vacuum
13
CMM-00000GU CMM-00000GU
In the thermovacuum drying and degassing mode the unitrsquos inlet is connected to the oil container
and the outlet is connected to
- transformer tank gate valve if the pressure in the transformer during filling is above 267 Pa
- transformer top gate if the pressure in the transformer is below 267 Pa
Transformer oil is pumped by P1 through valve MV1 and pre-filter MF the valve MV10 oil heater
H filter F1 electric valve V1 to vacuum chamber VC Hot oil (55hellip60ordmС) with particulate matter
removed passes through the activator filter (sprayer) in the chamber The vacuum in the chamber is
maintained by vacuum pumps VP1 VP2 The vacuum in the chamber is controlled by Pirani device with
DG1 sensor
Moist air is then expelled into the atmosphere through valve MV3 and oil trap OT by pumps VP1
and VP2
The oil from the chamber is pumped by pump P2 through valve MV9 filter F2 return valve ВV2
and ball valve MV2 and oil meter LC into the transformer
The vacuum in the chamber is maintained by the vacuum pumps Residual pressure (up to 267 Pa)
created in the vacuum chamber allows to achieve the required oil quality
When the oil passes through the chamber vacuum causes moisture and air to be removed from
the oil
In this mode the oil is filtered dried and degassed
To eliminate the chance of supplying poorly processed oil in the initial period of operation the unit
has a warm-up mode In this mode the vacuum chamber is filled with transformer oil then the oil is
heated by the hot oil which circulates in the following order
- vacuum chamber VС
- oil pump P2
- ball valve MV9
- filter F2
- ball valve MV4
- oil heater H
- filter F1
- electric valve V1
During circulation it is possible that the output pump stops due to oil level falling below the low
level sensor To avoid this fill the unit with oil to the level higher than the low level sensor
To prevent oil (or foam) from entering the vacuum system the vacuum chamber is equipped with a
foam sensor LS4 which opens valve V3 to reduce foam level Also oil trap OT is equipped with a level
sensor LS5 When oil or foam enters the vacuum system and activates LS5 an alarm is counded the
input and output pumps P1 and P2 stop as well as vacuum pumps VP1 VP2 Electromagnetic valve V1
stops the flow of oil into the vacuum chamber Electromagnetic valve V3 opens to facilitate foam
removal
If the unit loses power supply the electromagnetic valve V1 stops oil input into the vacuum
chamber it also closes in case of overheating of oil in the oil heater

421 The unit can be operated in the following modes
ndash laquoHeating and filtration (HampF) and vacuumizing of external equipment (VAC)raquo
ndash laquoThermovacuum heating (DRY) and degassing (DEG)raquo
422 In oil heating and filtration mode unprocessed oil enters the unit through ball valve MV1
pre-filter MF is supplied by pump P1 through valve MV10 oil heater H cartridge filter F1 electric
valve V2 return valve ВV3 oil meter LC valve MV2 to the outlet of the unit
The oil is filtered and heated in this mode
In this mode the heater and the pump P1 can be controlled Control of the P2 pump is
locked
It is also possible to control vacuum pumps VP1 and VP2 for vacuumizing external
equipment
Vacuumizing of a transformer is performed by pumps VP1 and VP2 through the vacuumizing
connector
423 Transformer oil is degassed by heat and vacuum
13
CMM-00000GU CMM-00000GU
In the thermovacuum drying and degassing mode the unitrsquos inlet is connected to the oil container
and the outlet is connected to
- transformer tank gate valve if the pressure in the transformer during filling is above 267 Pa
- transformer top gate if the pressure in the transformer is below 267 Pa
Transformer oil is pumped by P1 through valve MV1 and pre-filter MF the valve MV10 oil heater
H filter F1 electric valve V1 to vacuum chamber VC Hot oil (55hellip60ordmС) with particulate matter
removed passes through the activator filter (sprayer) in the chamber The vacuum in the chamber is
maintained by vacuum pumps VP1 VP2 The vacuum in the chamber is controlled by Pirani device with
DG1 sensor
Moist air is then expelled into the atmosphere through valve MV3 and oil trap OT by pumps VP1
and VP2
The oil from the chamber is pumped by pump P2 through valve MV9 filter F2 return valve ВV2
and ball valve MV2 and oil meter LC into the transformer
The vacuum in the chamber is maintained by the vacuum pumps Residual pressure (up to 267 Pa)
created in the vacuum chamber allows to achieve the required oil quality
When the oil passes through the chamber vacuum causes moisture and air to be removed from
the oil
In this mode the oil is filtered dried and degassed
To eliminate the chance of supplying poorly processed oil in the initial period of operation the unit
has a warm-up mode In this mode the vacuum chamber is filled with transformer oil then the oil is
heated by the hot oil which circulates in the following order
- vacuum chamber VС
- oil pump P2
- ball valve MV9
- filter F2
- ball valve MV4
- oil heater H
- filter F1
- electric valve V1
During circulation it is possible that the output pump stops due to oil level falling below the low
level sensor To avoid this fill the unit with oil to the level higher than the low level sensor
To prevent oil (or foam) from entering the vacuum system the vacuum chamber is equipped with a
foam sensor LS4 which opens valve V3 to reduce foam level Also oil trap OT is equipped with a level
sensor LS5 When oil or foam enters the vacuum system and activates LS5 an alarm is counded the
input and output pumps P1 and P2 stop as well as vacuum pumps VP1 VP2 Electromagnetic valve V1
stops the flow of oil into the vacuum chamber Electromagnetic valve V3 opens to facilitate foam
removal
If the unit loses power supply the electromagnetic valve V1 stops oil input into the vacuum
chamber it also closes in case of overheating of oil in the oil heater

CMM-00000GU CMM-00000GU
In the thermovacuum drying and degassing mode the unitrsquos inlet is connected to the oil container
and the outlet is connected to
- transformer tank gate valve if the pressure in the transformer during filling is above 267 Pa
- transformer top gate if the pressure in the transformer is below 267 Pa
Transformer oil is pumped by P1 through valve MV1 and pre-filter MF the valve MV10 oil heater
H filter F1 electric valve V1 to vacuum chamber VC Hot oil (55hellip60ordmС) with particulate matter
removed passes through the activator filter (sprayer) in the chamber The vacuum in the chamber is
maintained by vacuum pumps VP1 VP2 The vacuum in the chamber is controlled by Pirani device with
DG1 sensor
Moist air is then expelled into the atmosphere through valve MV3 and oil trap OT by pumps VP1
and VP2
The oil from the chamber is pumped by pump P2 through valve MV9 filter F2 return valve ВV2
and ball valve MV2 and oil meter LC into the transformer
The vacuum in the chamber is maintained by the vacuum pumps Residual pressure (up to 267 Pa)
created in the vacuum chamber allows to achieve the required oil quality
When the oil passes through the chamber vacuum causes moisture and air to be removed from
the oil
In this mode the oil is filtered dried and degassed
To eliminate the chance of supplying poorly processed oil in the initial period of operation the unit
has a warm-up mode In this mode the vacuum chamber is filled with transformer oil then the oil is
heated by the hot oil which circulates in the following order
- vacuum chamber VС
- oil pump P2
- ball valve MV9
- filter F2
- ball valve MV4
- oil heater H
- filter F1
- electric valve V1
During circulation it is possible that the output pump stops due to oil level falling below the low
level sensor To avoid this fill the unit with oil to the level higher than the low level sensor
To prevent oil (or foam) from entering the vacuum system the vacuum chamber is equipped with a
foam sensor LS4 which opens valve V3 to reduce foam level Also oil trap OT is equipped with a level
sensor LS5 When oil or foam enters the vacuum system and activates LS5 an alarm is counded the
input and output pumps P1 and P2 stop as well as vacuum pumps VP1 VP2 Electromagnetic valve V1
stops the flow of oil into the vacuum chamber Electromagnetic valve V3 opens to facilitate foam
removal
If the unit loses power supply the electromagnetic valve V1 stops oil input into the vacuum
chamber it also closes in case of overheating of oil in the oil heater
