Guidelines for Selection of transformer oil purification plant as per requirements

Basic Design: Double Stage Vacuum Transformer Oil Purifier Design (Two Stage Plant series ZYD) is suitable for filtration of high voltage transformers and Multiple Flow Pass design (Single Stage Plant series ZY) is suitable for low and medium voltage Transformers.

Flow Rate: is decided by the quantity of oil to be filtered and the time available for filtration.
Optional Items can be added depending on the need of filtration, oil purification such as Ionic Reaction Column for acidity removal, Filter Press for more dirt accumulation, Transformer Evacuation System for filtration and oil filling under vacuum.

Stationary / Portable / Mobile plants are selected according to place for filtration. Stationary plants are useful for transformer supplier / repairers who carry out filtration in factory. Mobile / Portable plants are suitable for filtration at site. Portable plants are more suitable when: a) the number of transformers to be filtered is large and, b) the location of transformers is difficult to reach with conventional trailer mounted machines.
