MAS6000 TYPE OIL TRETMENT EQUIPMENT
1.Treatment Process
The MAS6000 type oil treatment plant has been designed to treat dielectric oil
having a 50 ppm moisture content and a dissolved gas content of approx. 10% by
volume before being treated. With an appropriate pass number through the system,
the clean treated oil goes out at a maximum temperature of 80 oC with a moisture
content below 3 ppm* and a dissolved gas content of approx. 0.1% by volume*.
This restores the oil dielectric strength to a value in excess of 75 kv.
The above figures and reached with oil having a 10-2mbar distillation curve at a
temperature of 80 oC.
*
Theoretical value depending on the measuring device accuracy and reanging
from about 2 to 5 ppm.
2.Principle of Operation
The dielectric fluid enters the plant through an inlet strainer, and then passes
through an inlet oil pump and into an oil heater, where it is heated by immersion
heaters.
After a fine filtration on cartridge, the dielectric fluid is sprayed into a vacuum
chamber on a basket of “Raschig” rings”.
Contaminants being eliminated, the clean treated fluid flows through the outlet oil
pump.
