General Selection Guidelines
For medium purity application, a multiple flow pass-single stage plant with smaller vacuum system can be sufficient for higher purity and high flow rates, a single flow pass-two stage plant with larger vacuum system is recommended. However, it is recommended that the final selection is made in consultation with V.P.I. Mfg. Co. Ltd.

In the manufacture of electrical components and equipments such as Transformers, Switch gear etc. the use of insulating oils, such as Mineral Transformer oil, becomes indispensable. The Dielectrical properties of this oil may vary depending on the content of the Gas, Moisture, Suspended Particles, and other contaminants. Even new oil absorbs gas and moisture while in storage. Prior to its use, therefore, it has to be reconditioned. Reconditioning and purification of the oil is also necessary due to absorption of gas and moisture during service and due to development of ageing products. V.P.I. Mfg. Co. Ltd. manufacturers a variety of plants for the purification and reconditioning of the mineral Transformer oil to relevant specifications. these plants cover the entire range of low, medium , high and extra high voltage equipment such as transformers. The emphasis is always on the user requirements and thus all the plants are tailored to suit the customer specifications. These plants of various design and capacities carry out the following operations:
- Removal of suspended particles by filtering,
- Degassing and dehumidification,
- Flushing and cleaning of transformers,
- De-acidification orem.com
