Under normal circumstances, the single stage Vacuum filter plant is extremely effective. However in exceptional cases where a higher state of vacuum is required to maintain low value of dissolved gases and moisture, we offer a double or three stage vacuum filter.
Added advantage of this system include the facility of improving quality of filtered oil to a higher level under single pass at a temperature of about 60C.
Special Features : In addition to the above, the following special features can be  incorporated in the plant
- (a) Alarm Annunciators
- (b) Moisture Content meter
- (c) Gas content meter
- (d) Digital Electronic measuring Instruments
- (e) Oil Flow meter
- (f) Transformer evacuation system
Ionic Reaction Coloumn : In certain cases where there is need for decrease in acid content of transforer oil, an ionic reaction coloumn is provided complete with first file up of high grade neutralizing chemicals, an SS wire mesh for supporting media.
