Transformer Oil Purification Machine – FLD 77D

• Description

  FLD 77D oil purifiers remove dissolved gases, free water, dissolved water and particulates from oil. This machine is equipped with a two-stage vacuum system, so it can also be used for vacuuming power transformers.

• 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 77D 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 77D oil purifiers can be used for heating transformer oil, filling oil into a transformer under vacuum, or vacuuming the transformer.
