ZLA series high-efficiency double-stage vacuum oil purifier is a typical product, developed and produced by Wanmei company as a special equipment for dehydration, degassing, purification process of various kinds of insulating oils in electrical transformers and circuit breakers etc. It is designed on vacuum drying principle, coalescence and separation technique, accurate fine filtration and other Wanmei patented technique.
Application scope:
ZLA series is widely used in purification of various kinds of insulating oil, especially the fine purification treatment of high-grade new oil, imported oil and super-voltage transformer oil. It can be used for onsite operation in over110KV transformers, especially even in high-latitude areas. ZLA series also can be used as dehumidification equipment for a variety of electric facilities. And it is widely used for oil filling for transformers and circuit breakers under vacuum condition. It is suitable for high-efficiency purification process for other low-viscosity lubricating oils.
Characteristics:
1. Double-stage, high vacuum pressure and high flow rate that help remove water, air, gases, solid particulates and other impurities from oil quickly and efficiently so as to improve the breakdown voltage of oil and maintain its insulating property.
2. Advanced dehydrating and degassing system that uses large area three-dimensional flash distillation technique to remove harmful composition in the oil, such as water, air and gases.
3. Precise fine multi-stage filtration helps remove mechanical impurities in oil; high-quality filter element is of corrosion proof, strong mechanical strength and wear resistance.
4. Sensitive automatic pressure protection device and infrared oil level control system make the operation even easy, simple and safe.
5. It possesses the function of vacuuming electrical equipment and oil filling under vacuum condition. It can be used to treat low-viscosity lubricating oils. It is more efficient than other single-stage vacuum oil purifier.
