High Vacuum Transformer Oil Filtration and Dehydration Plants |
High-Vacuum Transformer Oil Filtration And Dehydration Plants are suitable for all types of electrical insulating oils. We have standard high-vacuum filtration and dehydration plants to remove moisture (free as well as dissolved), gases, dirt and oxidation products from mineral-based and synthetic, silicon oils and others. Systems are in flow rates from 300 LPH to 12000 LPH. Custom built plants can be provided as per customer’s specific requirement, such as more flow-rates. These plants work on low temperature, high vacuum principle. Plants mainly consist of heating, filtration and vacuum system. Heating system aids to the filtration and moisture removal. Filtration systems remove suspended particles down to 1 micron such as rust, dirt, scales, colloidal carbon etc. Vacuum Systems remove moisture (emulsified as well as dissolved) down to < 5 – 10 ppm depending on the working vacuum of the plant.

Industrial Oil Purification Systems
Oil purification systems are designed & manufactured to suit the specific requirement of the customer. Normally the oil is deteriorated by contamination of foreign particles, moisture (free & dissolved), oxidation sludge etc. The deteriorated oil affects the performance of the equipment in which it is used because of change in properties. Different modules are designed to remove particular types of contaminations. The purification system normally consists of filtration / purification stages for economical operation. In pre filtration stage coarse particles are removed using cleanable / washable elements. In intermediate stage the major portion of the contaminants removed by using the properly selected filter elements suitable for oil to be purified. In final stage the fine contaminants are removed by special elements to suit the final application and purification level. The free moisture removal is carried out either by gravity separation methods such as spirafuge, centrifuge or by using coalescer elements. Dissolved moisture is removed partially by coalescer elements and finally by vacuum treatment. Following modules are used frequently in oil purification systems:
