Description
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.

Advantages
Fluidex’s vacuum oil purifier offers several significant advantages. Firstly, it increases the dielectric strength of the transformer oil to at least 75 kV, ensuring superior insulation performance and reliability. Additionally, the system facilitates the simultaneous drying of transformers while processing the oil, enhancing the overall efficiency of maintenance operations. This equipment is also adept at the initial filling of electrical apparatus with insulating oil, providing a clean and contamination-free environment for optimal functioning. Furthermore, it allows for the evacuation of transformers and other electrical equipment, ensuring the removal of moisture and air to prevent dielectric breakdown. The system is designed for straightforward operation and maintenance, making it user-friendly and cost-effective for long-term use.

Application
FLD 26.4D oil purifiers with a two-stage vacuum system can be used in the energy sector and other industries for filtering, drying, and deep degassing of the following types of dielectric fluids:
- transformer oils;
- silicone oils;
- Midel 7131 dielectric fluids;
- FR3 fluids.
Additionally, FLD 26.4D oil purifiers can be used for heating transformer oil, filling oil into a transformer under vacuum, or vacuuming the transformer.
