ZLA Two-Stage Vacuum Oil Purifier Serie series is widely used in purification of various kinds of insulating oil. The super big absorptive two stage vacuum purifies all insulation oil of power equipment rapidly and in more depth which removeswater, gas and impurity in the oil rapidly and effectively with the support ofhigh vacuum and absorption speed. Thus the strength of insulation oil is much increased and the time for oil treatment is shortened. Characteristics:1) Big absorption speed double vacuum satisfies the needs of vacuum zing of transformer on an installation or repair site, and the water/gas removal of transformeroil can be completed at same time, which shortens significantly the time foroil treatment. 2) A unique gas/water removal system adopting stereo-evaporation technology, which rapidly separates the water and gas content in the oil and the system, improvesthe breakdown voltage of oil and maintain its insulating property. 3) A superior purification system with top quality filter core, which can accommodate large quantity of dirt and is dandified progressively step by step. The filtercore has got a high precision and multi-stage filtration. 4) An advanced infrared liquid level control system with automatic control, allowing separated operation of manual operators from a machine. 5) Purifiers are equipped with an interlocked safety protective device. I.E, backflow of A oil outlet over pressure can be achieved via an overflow valve, B oilinlet will interlock with heating system which avoids any possible negative impacts caused by mal-operation 6) Precision oil pumps for designated purpose are used, which have low noise and environmental regulatory compliance is well met
