Double stage vacuum transformer oil purifier

The dissolved water, gas and particles would influence the transformer oil’s dielectric strength and reduce the electrical efficiency and lifetime of the transformer; our company develops and designs series ZYD high vacuum transformer oil purifier. ZYD adopts advanced double stage vacuum system, including vacuum pump and roots pump, which can rapidly and effectively remove water, trace water, gas. ZYD transformer oil purifier also equips high precision cartridge-type filters, which has large particle holding capacity and can provide one micron filtration. Besides, series ZYD oil purifier can be used as independent vacuum source with functions of vacuum drying and vacuum filling for transformers and electric equipments.
