The FLD 26.4D machine is recognized for dielectric oil treatment having a 50 ppm moisture content and a dissolved gas content of approx. 10% by volume before being treated.
Parameters of the treated oil after one pass through the machine:
- maximum temperature – 80°C;
- moisture content – less than 5 ppm;
- dissolved gas content – approximately 0.1% (or less) by volume;
- breakdown voltage – excess of 75 kV.
Under the same conditions an oil at 20 ppm will go out at 3 (or less) ppm after one pass.
The above figures are reached with oils having a 10-2 mbar distillation curve at a temperature of 80° C.
Principle of operation
The dielectric fluid enters the system through the inlet strainer, then enters the oil heater where it is heated by immersion heaters. After being finely filtered on a 25 micron cartridge, the dielectric fluid enters a vacuum chamber where it is atomized through filter activators. Finally, after the removal of contaminants, the clean treated liquid is pumped out by an oil pump and flows through the finishing filter, meter and outlet valve to the outlet of the machine.
