TRASFORMEROIL FILTRATION AND DEHYDRATION PLANT

We manufacture different types of plants for the purification / up-gradation of the mineral Transformer Oil to standard specifications. These plants cover entire range of low, high and extra high voltage equipment such as transformers. These Plants are designed and manufactured to suit specific requirements of customers.The plants are available in various designs and capacities to carry out following operations:Removal of all suspended particles such as dust, rust, scales, colloidal carbon oxidation sludge etc. up to 1 micron. Degassing and Dehumidification of Transformer Oil under vacuum. Circulation of heated Oil and Filling of treated oil in Transformer tank. De-acidification by evaporation and adsorption method.Our single stage plants are capable of attaining following oil parameters in 3-4 passes andTwo Stage Plants in 1-2 passes :ProductHighlights1. Designed And Manufactured To Suit Customer's Requirement2. Plants With Minimum And Easy Maintenance3. Low Operating Cost Due To High Vacuum Filtration With Rotary Oil Sealed Pumps4. Plants Are Also Suitable For Hydraulic Oil, Turbine Oil, Etc.MajorComponentsOIL TRANSFER & CIRCULATING SYSTEMMainly consists of inlet pump (Gear type positive displacement), Outlet pump (positive displacement Gear type or Multistage Centrifugal) and necessary valves & piping to ensure easy operation and maintenance. Complete system is vacuum tight to have a leak -proof operation.HEATING SYSTEMIt is capable of heating the oil 25 o C to 80 o C. It contains insulated heat exchanger with indirect low watt density (Less than 2 W/cm2) bobbin type electric heaters. Oil temperature is controlled with thermostat. Suitable oil distribution system is provided to ensure uniform flow of oil over heaters.FILTRATION SYSTEMIt is suitable for removing suspended particles such as colloidal carbon, oxidation sludge, dirt, rust, scales up to 1 micron. It consists of PRE FILTER and FINE FILTER.PRE FILTERIt is a metallic strainer with magnet. It removes magnetic and coarse suspended particles and to protect inlet pump from damage due to abrasion.FINE FILTERRemoves all suspended particles up to 1 micron. Filter Elements are either non-hygroscopic molded cellulose cartridges or cleanable (with reverse airflow) edge type filter candles. Filter cartridges are easily replaceable. Additional Intermediate filter can be provided to increase life of fine filter.DEGASSING & DEHYDRATION CHAMBERIt is designed to remove large portion of dissolved impurities (Including Moisture) from oil. Rasching ring trays and oil dispersing system are provided to have sufficient exposure of oil to vacuum during filtration. Oil level is controlled with float switch.VACUUM SYSTEMRotary oil-sealed vacuum pump or combination of Mechanical Booster Pump and Rotary oil-sealed pump is provided to get proper working vacuum during filtration. Necessary valves for easy operation and maintenance of the plant.CONTROL PANELCentralized control panel is provided with necessary contactors, overload relays, fuses, push buttons, indicating lamps, main switch etc. for easy and safe operation of the plant.OPTIONAL ITEMSIonic Reaction Column for acidity removal.Transformer Evacuation System.Filter Press as an intermediate filter to increase the cartridge life.Additional Instrumentation such as Temperature Indicating Controller, Flow Meter,On-line Oil Testing Equipment.TRANSFORMER OIL FILTRATION & DEHYDRATION (SINGLE STAGE)These plants are designed for filtration and dehydration of Power and Distribution Transformers and oil in tank. These plants can also be used for hot oil circulation in transformers and transformer drying. These plants are available in Series S (Stationery Units), Series P (Units on Castors) and Series M (Units on Trailer)TECHNICALSPECIFICATIONS
