ZLA Series Double-Stages High Efficiency Transformer Oil Purifier
ZLA series double-stages vacuum high efficiency transformer oil purifier is 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.
ZLA series transformer oil purifier is widely used in purification of all 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 over 110KV transformers, especially even in high-latitude areas. ZLA series transformer oil purifier 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 also suitable for high-efficiency purification process for other low-viscosity lubricating oils.
Double-stages, 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.
Advanced dehydration 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.
Fine multi-stage filtration helps remove mechanical impurities in oil; high-quality purifier element is of corrosion proof, strong mechanical strength and wear resistance.
Sensitive automatic pressure protection device and infrared oil level control system make the operation even easy, simple and safe.
ZLA series transformer oil purifier possesses the function of vacuuming electrical equipment and oil filling under vacuum condition. It can be used to treat low-viscosity lubricating oils.
ZLA series transformer oil purifier is more efficient than other single-stage transformer oil purifier.
