Transformer Oil Filtration and Dehydration Plant
AR Engineering is one of the leading manufacturers of Transformer oil filtration & dehydration plants since 1990. The company got established in 1988 at Satara, Maharashtra. Sticking to our policy, we try to manufacture machine which will give lowest running cost to our customers. Keeping in mind that, our machines are compact (Less floor space occupied), light weight (Less transportation cost) & higher working vacuum (Less oil heating in the machine) We manufacture transformer oil filtration & dehydration plants ranging from 300 LPH to 18000 LPH. Each model having 2 types mainly, single stage degassing & 2 stage degassing. Working vacuum of single stage degassing plants is less than 1 Torr. While working vacuum 2-stage plants is less than 0.2 Torr. Our machines are work on Low temperature high vacuum principle. So, running cost of our machine is very minimal. We also manufacture tailor made plants for our customers such as transformer oil regeneration plants. Recently we have introduced the new series (HV) in addition to single stage (1V) & two stage (2V) of transformer oil filtration & dehydration plants.

Single Stage Degassing System
single-stage-degassing-system
These type of transformer oil filtration & dehydration plants mainly used for filtration of distribution transformers. In these types, machine consists of single stage degassing chamber connected to single vacuum pump with high ultimate vacuum. From these machines, you will achieve the desired results within 3 to 5 passes of oil through the machine.

Two Stage Degassing System
single-stage-degassing-system
These type of transformer oil filtration & dehydration plants mainly used for filtration of power transformers where transformer downtime is very less & results need to be achieved at higher rate. In these types, machine consists of double stage degassing chamber separated by siphon & 50 mm oil head with first stage connected to single vacuum pump & 2nd stage connected to roots-rotary combination of vacuum pumps with working vacuum in the range of 0.1 to 0.2 mbar. From these machines, you will achieve the desired results within 2 to 3 passes of oil through the machine.
