Transformer Oil Purification Machine – FLD 26.4D
The FLD 26.4D transformer oil purification machine is recognized for treatment of dielectric oil with a mass moisture content of 50 ppm and a volumetric dissolved gas content of approx. 10% before being treated.
Note. The photo shows the machine in a frame-type version. At the customer's request, the machine can be manufactured on a road speed trailer (80 km/h).-
Description
The FLD 26.4D oil filtration machine is recognized for treatment of dielectric oil with a mass moisture content of 50 ppm and a volumetric dissolved gas content of approx. 10 % 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 — above 75 kV.
Under the same conditions, oil with a moisture content of 20 ppm will leave the system, indicating 3 (or less) ppm after one pass.
The above values are achieved 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 an inlet mesh filter, then flows through an oil heating assembly where it is heated by immersion heaters. After being finely filtered on a 25-micron cartridge, the dielectric fluid enters the vacuum chamber where it is atomized through filter-activators. Finally, after the contaminants are removed, the purified fluid leaves the system through an outlet oil pump and flows through a finishing filter, a meter, and an outlet valve to the machine outlet.

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

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