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

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

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

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

During operation of the equipment it is necessary to dispose of consumables as well as of the

equipment when the unitrsquos life time ends

Disposal procedure requires strict adherence to the local territorial regulations with regard

to sanitary environmental and other safety measures

The manufacturer suggests the following procedures for disposal (when such procedures are not

explicitly outlined locally) as follows

- dispose of filtering elements by separation of metal elements from the filtering medium Dispose

of the metal by submitting it to recycling centers the remaining components can be disposed of as is

usual for ordinary waste

- dispose of the equipment by disassembling the unit into separate components and subassemblies

All components are to be disposed of as per their respective manuals Submit the components to

recycling centers (metal rubber etc)

- dispose (if required) of oil and contaminants by burning in furnaces or submit to specialized

agencies for disposal (destruction) of the substance
