AR Engineering is a company founded by Mr. Arvind Mutalik in 1988, for manufacturing of transformer oil filtration machines. Since then AR Engineering has developed different types of Insulating Oil upgrading systems suitable for in-house and onsite operation.
We also manufacture Vacuum Impregnation Plants for big electrical windings and Vacuum Drying Ovens for drying of transformers, capacitors etc. On line transformer oil regeneration plants are under development.
Our Customer list includes clients ranging from small oil filtration service providers to big customers like NTPC, BHEL, NHPC, various electricity boards etc. Our plants are working all over India and countries such as Saudi Arabia, Jordan, Qatar, Iraq, Nepal, Bangladesh, Zambia, Equator, Egypt, Turkey etc.
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. Manufacturer Of Transformer Oil Filtration Plants
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.

How To Configure The Model
Transformer / Insulating Oil Filtration and Dehydration Plants / Purifiers are available for:
1. Transformer and capacitor manufacturers – skid mounted plants for preparation of new oils prior to apparatus filling and impregnation.
2. Transformer repairers – 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.
3. Transformer owners – 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.
This High-Vacuum Transformer Oil Filtration And Dehydration 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
Generally the plants are as per the schematic diagram attached. The plants mainly consist of following major components:
Working Systems
OIL TRANSFER & CIRCULATING SYSTEM :
It mainly consists of Inlet Pump (Gear type positive displacement), Outlet Pump (Positive displacement Gear type or Glandless Centrifugal) and necessary valves & piping as per the schematic diagram to ensure easy operation and maintenance. Complete system is vacuum tight to have a leak-proof operation. The piping joints are flanged type with O’rings. Chambers are provided with suitable draining arrangement.
HEATING SYSTEM :
1. It is capable of heating the oil from 25°C to 80°C. It contains Insulated heat exchanger with indirect low watt density (Less than 2W/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. It will be provided with:
2. Indirect Type Heating Elements made out of Nichrome wire elements fixed in refractory formers and inserted in finned MS tubes welded to heater chamber plate. Watt Density will be less than 2 Watts / cm2.
3. Temperature Control: Thermostatic
4. Temperature Indication: Dial Stem Type Thermometer.
5. Thermal Insulation: Glass Wool enclosed with CRCA sheets
FILTRATION SYSTEM :
It is suitable for removing suspended particles such as colloidal carbon, oxidation sludge, dirt, rust, up to < 1 micron. It consists of PRE FILTER, INTERMEDIATE FILTER and FINE FILTER elements
PRE FILTER: is a metallic strainer with magnet. It removes magnetic and coarse suspended particles and to protect inlet pump from damage due to abrasion.
FINE FILTER: removes 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 is provided to increase life of fine filter element
