ZYD double-stage vacuum transformer dielectric oil dehydrator plant is applied for heating, eliminating moisture, particulate matters and unnecessary gases of contaminated insulating oil used in transformers, mutual inductors, circuit breakers and switches. It is specially suitable for on-site installation, maintenance and purifying high level new oil, or running oil from big power transmission and distribution equipment and transformers on national main power transformation grid, which is above 110-750KV. It is an affordable centifuge oil machine in order to centrifugate dielectric oil for transformers.

The unit can carry out oil treatment, vacuum oil injection and cyclic hot oil drying in the installation and maintenance of transformers. It also can be mobile, 4 wheel mounted type and configured into double-stage high-vacuum oil filters to meet the greater needs for oil treatment.
With our special regeneration unit, it can change black color to original color and recover other oil properties.

1. Can purify large power transmission equipment above 110kv.
2. Equipped with roots pump, powerful double-stage vacuum system
3. Continuously working for 150 hours
4. Duplex 3D evaporation technology and precise multi-stage filtration system
5. Carbon fiber infrared heating system

6. Automatic double-infrared liquid controller and pressure protector
7. Interlocked protective system
8. Automatic back-flushing system
9. It can purify transformers running with electricity.
