Online transformer oil filtration allows purification while the transformer remains energized. This is especially useful in industrial plants where power cannot be interrupted. Fluidex online filtration units are engineered with safety features that enable real-time oil treatment without shutdowns. These systems continuously remove water and gases, ensuring the oil remains within dielectric standards. It’s a smart maintenance solution for facilities where uptime is critical, such as chemical plants, paper mills, or manufacturing hubs.

A turbine oil purification plant operates by continuously processing contaminated oil to restore its lubricating and cooling properties. The process involves:

Heating the oil to reduce viscosity and facilitate the removal of moisture.
Vacuum dehydration to remove water and gases.
Filtration to capture solid particles such as dirt and sludge.
Centrifugation to further separate water and contaminants from the oil. After purification, the oil is tested for quality and recirculated back into the turbine system.

**Degassing oil purification** works by removing dissolved gases and air bubbles from the oil, which can negatively impact its dielectric strength and insulating properties. The process typically involves the following steps:
1. **Heating:** The oil is heated to lower its viscosity, making it easier to remove gases and other contaminants.
2. **Vacuum Chamber:** The heated oil is passed through a vacuum chamber. In a low-pressure environment, gases dissolved in the oil are released and evaporated. This process also helps remove any entrained air that may have been introduced into the oil.
3. **Separation:** As the gases are drawn out of the oil, they are separated from the oil and removed from the system via vacuum pumps.
4. **Filtration (Optional):** The oil may also pass through filtration systems to remove solid particles and moisture in addition to degassing.
5. **Recirculation:** The degassed oil is then recirculated back into the transformer or equipment, where it continues to insulate and cool efficiently.
Degassing improves the dielectric strength of transformer oil, which is crucial for preventing electrical discharges and ensuring the proper operation of transformers or high-voltage equipment.

Used oil is purified through processes like filtration, centrifugation, and vacuum dehydration. The oil is first heated to lower viscosity, making it easier to filter out contaminants such as dirt, metal particles, and sludge. Filtration and centrifugation remove solid particles, while vacuum dehydration eliminates water and dissolved gases. Some used oils, like transformer oil, may also undergo chemical treatment to remove acids and other degradation products.
