Transformer Oil Treatment
DC-4.4P Transformer Oil Purification Machine
The DC-4.4P oil purification machine performs key functions required for maintaining industrial and transformer oils in proper operating condition: removal of mechanical impurities through multi-stage filtration, removal of water and dissolved gases using thermal vacuum technology, heating and circulation of oil and preparation of oil for operation in electrical equipment.
Description
The DC-4.4P oil purification machine performs key functions required for maintaining industrial and transformer oils in proper operating condition:
- Removal of mechanical impurities through multi-stage filtration.
- Removal of water and dissolved gases using thermal vacuum technology.
- Heating and circulation of oil.
- Preparation of oil for operation in electrical equipment.
This combination of processes ensures improved dielectric strength, reduced moisture content, and extended service life of the oil.
The DC-4.4P features a compact and efficient design achieved through optimized component layout:
- The heater is integrated inside the vacuum tank, reducing heat loss and improving energy efficiency.
- Oil intake into the vacuum chamber is ensured by underpressure generated by the vacuum system.
- The internal configuration of the unit is designed to minimize overall dimensions while maintaining high performance.
- Multi-stage filtration system ensures effective removal of contaminants at different levels.
These design solutions allow the unit to combine compact size with high operational efficiency.
