CTBU Thermo vacuum transformer oil filtration unit can quickly remove moisture water, gas, particles as well as acetylene, hydrogen, methane and other harmful ingredients from oil effectively to improve oil's BDV. Model ZLS oil filtration unit is particularly suitable for treating high voltage transformer oil, super-voltage transformer oil and new transformer oil.
Features:
1• Increase the transformer oil's dielectric strength level as per the standard of ASTM 877 or IEC60156, IEC60296.
2• Different vacuum degassing chamber design, includes T shape, horizontal shape and vertical shape
3• High micron filter grade with capable of removing 99.5% particles ≤1 μm.
4• The final oil's moisture content can be less than 5 PPM By vacuum degassing to remove free water, emulsified and dissolved water.
5• with low watt-density less than 1.5W/cm2 heater
6• instrumentation, including pressure gauge, vacuum gauge, thermometer, etc.
