    Plant Specifications

    The purifiers are designed for filtration of transformer oil in workshops, storage tanks, drums or directly in transformers. Purification of oil in transformers can be carried out off-load or on-load depending on customers preference.

    Water Removal : Water is removed by heating the oil passing it through coalesces inside a vacuum chamber. During this process water and oil are separated and clean dry insulating oil are returned to the transformer.

    Gas Removal: During the vacuum stage of the process, dissolved gasses are removed from the oil leaving it clean, dry and gas free.

    Oxygen, as an accelerator of oxidation, is also removed.

    Particulate Matter Removal: 98% of all particles over 0.5 micrometres are removed.

    Dielectric Strength: Improvement in dielectric strength, up to 70 kV, with new oil.
