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 UNITS FAQ'S QUESTIONNAIRETransformer / Insulating Oil Filtration and Dehydration Plants / Purifiers are available for :
Skid mounted plants for preparation of new oils prior to apparatus filling and impregnation.
Complete plants for preparation of new oils and regeneration of used oils for reuse. We can provide the purification system you need as well as vacuum storage tanks and transformer filling and emptying / pumping station.
Portable plants are available in a variety of trailer-types and sizes to allow on-site servicing of transformer oil right in the substation. Trailers are available with a wide variety of options including laboratory space, oil-testing equipment. Plants are designed for drying out of the transformer insulation and oil filling and impregnation under vacuum. Hot oil circulation and hot oil spray methods can also be used.
Plants are available in different types of constructions such as open & enclosed models, stationery, portable & mobile models, with single & double stage degassing / dehydration system. Our single stage plants (Models 1V) are capable of attaining following oil parameter in 3-5 passes and Two Stage Plants (Models 2V) in 1-3 passes depending on the oil condition:

Ionic Rreaction Column
It will be fabricated out of MS sheets, plates. It will contain sufficient quantity of activated alumina (** Kgs) for reduction of acidity level of oil to less than 0.05 mg of KOH / gm oil. It will be provided with, By-pass arrangement when not necessary & Alumina Cage (fabricated with CRCA caps & SS wire mesh) for easy replacement. It is fitted on the plants of flow rate > 2400 LPH as a standard fitting and bypass arrangement.
Transformer Evacuation System
It will be suitable for working vacuum of either 5 – 10 torr or 0.1 – 0.5 torr. It will be provided with Rotary Oil Sealed Pump or Roots Rotary combination along with Moisture Traps (water cooled) with drain, airing valve, NRV, Vacuum Gauge will be provided as per the schematic diagram.
