Product features:
The various indicators of the product are significantly higher than the national standards. Compared with single-stage vacuum oil filters, its dehydration, degassing, and impurity removal (mechanical impurities and free carbon) effects are faster and more thorough. The oil's ultimate withstand voltage and flash point are higher, and the breakdown voltage of a single filtration can be increased by 35KV, reducing the harm of oil aging caused by repeated heating in general oil filters.

The two-stage vacuum with high pumping rate can maximize the vacuum environment inside the tank, achieving high vacuum with a maximum vacuum of ≤ 5Pa and a working vacuum of ≤ 35Pa. This ensures that the oil temperature remains constant during the processing, meeting the needs of vacuum pumping on the transformer body during installation or maintenance, greatly shortening the oil processing period.

The unique degassing and dehydration system, combined with three-dimensional flash evaporation, can quickly remove liquid water. Using UK microgram technology, it can effectively remove trace amounts of dissolved water and other moisture, efficiently completing the degassing, dehydration, and treatment of transformer oil, improving the insulation strength and oil quality of the oil.

Excellent filtration system, dual mesh filtration combined with polymer material filter element for impurity removal technology, high-quality filter element, using step-by-step encryption technology, multi-stage precision filtration, high filtration accuracy, large scale capacity, high strength, and long service life.

Schneider imported electrical system from France ensures high-performance operation of the equipment, and the whole machine can run with electricity. Fully automatic infrared liquid level control system, human-machine separation operation.

Humanized design, high degree of automation, equipped with a simple operating system and advanced safety system, fully ensuring the convenience and safety of machine operation, and can work online for a long time. Unique oil pump technology, maintaining low noise, special chassis structure design, ensuring no ground pollution during operation, in line with the high environmental standards of the world.

Advantageous Technology:
Compared with single-stage vacuum oil filters, this equipment can dehydrate, degas, and remove impurities faster and more thoroughly; Higher oil ultimate pressure resistance value; One machine dual-use, it is an oil filter and an independent vacuum source, which can perform vacuum oil injection on power insulation equipment; It can significantly shorten the oil treatment period for transformer installation and maintenance, and also greatly improve the oil quality indicators of various imported and new oils!
