It is widely used in the oil purification treatment and vacuum hot oil circulation drying in the installation and maintenance of various large transformer equipment.. Not only use in Insulating oil purification treatment in 110KV-550KV transformer,but also applies to high-grade new oil, the high depth of processing imported oil. Compared with the single-stage vacuum purifier machine, the machine increases the Roots pump pressurization system,secondary high vacuum separation systems and three-dimensional flash rapid evaporation system , it can quickly dewater, degas, and remove the acetylene, acid value and free carbon , The transformer oil limit Breakdown voltage value will be higher after treated,It â€˜s not only used for oil purifier but also as a separate vacuum source which have the function of vacuum drying and oil injection for transformer equipment

hey filter out all the contaminants and particles from the feed water source once it has passed through pretreatment. Crossflow membrane filtration is a pressure-driven separation process. Application: Industrial, food, water, chemical, and biotechnology markets, as well as for those providing environmental protection. RO membranes are great solutions for many different applications. Membranes serve as highly-engineered, physical barriers that permit the passage of materials only up to a certain size, shape or character. Puritech offers reverse osmosis membranes (RO membranes), Filmtec membranes or Dow Filmtec membranes, Koch membranes, and Hydranautics membranes in a variety of configurations, materials and sizes; each designed to meet specific application needs. Puritech also stocks their brand of spiral membranes.
