FLD 20D Vacuum Oil Purifier

• Description

  FLD 20D oil purifiers remove dissolved gases, free and dissolved water, as well as particulate matter from oil. These machines are equipped with a two-stage vacuum system, so they can also be used for evacuation of power transformers.

• 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 processing the oil, 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 20D 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 20D oil purifiers can be used for heating of transformer oil, filling of the oil into a transformer under vacuum, or for vacuumizing of transformers.
