Completely discarded oil can be converted into new oil. It improves the major parameters of insulating oil, such as tan delta, resistivity, IFT, colour, etc. Widely used in the online desludging of transformers, it is also effective in improving oil parameters in testing oil stored in silos. Distillate polishing of re-refined waste oil is a popular application. Capacity ranges from 3000 LPH to 12000 LPH for insulating oil treatment, with customised capacity per ton/day for re-refined oil treatment. The process is eco-friendly, producing no harmful waste for disposal.
