Utilizing VTP Transformer Insulating Oil Purifier, the quality of insulation oil can be upgraded and the deteriorated oil can be reclaimed that could extent the life of insulating oil and ensure safety operation of oil-filled electrical equipment treatment. VTP Vacuum transformer insulating oil purifier can efficiently removes water, gas and solid contaminants. It removes free water by demulsification, coalescence and separation, after purification, the free water content is less than 5 PPM. VTP Transformer Insulating Oil Purifier separates solid contaminants by different precision filters elements, and recover cleanliness, the cleanliness can reach NAS 6 grade. Through the dehydrator, degasification, filtration processes, the dissolved gases and moisture, solid particulate, contamination can be completely removed. VTP Transformer Insulating Oil Purifier is widely used in factory workshops, power transmission, generation station etc.
