FUNCTION
The main function of DZL Series of signal and double stage high-efficient vacuum oil purifier is to remove free and dissolved water, gases, and mechanical impurities from insulating oils so as to ensure its purity and improve its insulation property. It is suitable for the application to oil treatment 500KV super-voltage transforming equipment and 220KV transformers. It is also suitable for the treatment of capacitor oil, transformer oil and freezer oil.

TECHNICAL FEATURES
1. Doubles the evaporation area by adopting Fengyu horizontal double vacuum separation technology efficiently and.reliability thorough removal of gas in the oil by using coalescing oil spray separator.
2. Adoption of American fine filter element, fineness: 5�gm, s?1000
3. Low noise and long life of the oil transport system
4. Adoption of American heating technique with the way of thermal radiation, constant temperature control.
5. The use of float valve and photoelectric oil level control, eliminates supervision
6. Adoption of French de-foaming technique to avoid oil leaking
7. Controlled digitally and automatically by PLC
8. Major electric apparatus are imported from America, so the controlling system safe and reliable
