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 transformer. It is also suitable for the treatment of capacitor oil, transformer oil and freezer oil. TECHNIQUE FEATURES ??Double the evaporation area by adopting Fengyu horizontal double vacuum separation technology efficient and reliable. ??Thorough removal of gas in the oil by using coalescing oil spray separator. ??Adopt American fine filter element, fineness: 5μm, ?#8805;1000 ??Low noise and long life of the oil transport system ??Adopt American heating technique with the way of thermal radiation, constant temperature control. ??Using float valve and photoelectric oil level control, no need of human supervision ??Adopt French defoaming technique to avoid oil leaking ??Controlled digitally and automatically by PLC ??Major electric apparatus are imported from America, so the controlling system safe and reliable
