High Vacuum Transformer Oil Filtration Machine
transformer oil purifier
Description

  DVTP Double Stages High Vacuum Transformer Oil Filtration Machine is designed and built for purification processing of electrical insulating oil in transformers and other oil-filled electrical equipment, especially applied for on-line or off-line purification of oil filled in HV, UHV and EHV transformers, transmission and distribution equipment, substation etc. Through the dehydration, degasification, filtration processes, the dissolved gases and moisture, solid particulate, contamination can be completely removed. DVTP Double Stages High Vacuum Transformer Oil Filtration Machine is very effective, durable, and user-friendly high vacuum purification system on the market today. Special engineered design features maximize the water extraction rates of our systems, and top-quality components and workmanship ensure years of maintenance-free operation and performance. Meanwhile, DVTP Vacuum Transformer Oil Filtration Machine also can be used for transformers vacuum drying and vacuum oil-filling.


Feature and Performance

● Upgrading of new and used electrical insulating liquids, transformer oils.
● Double stages vacuum pump, horizontal double vacuum dehydration, degasification chambers and blower capable of pulling vacuum down to 0.05 mbar.
● High efficiency three stage micro filter elements with capable of removing 99.5% particles as small as 1 micron.
● Maximum moisture content 1000 ppm to be processed, and can achieve overall water content of ≤3 PPM By vacuum dehydration to remove free, emulsified and dissolved water.
