Vacuum drying tank

The variable-pressure vacuum drying tank is a new vacuum drying technology developed in cooperation with foreign countries. It has changed the traditional drying method with high energy consumption, low efficiency and long cycle. It adopts steam phase drying technology with water steam as the heat carrier. In the stage of hot air heating, it USES the steam vaporized in the drying product and the dry air filled in the drying product as the heat transfer medium. It conducts heat exchange in the heater and the dried product. The drying process of stepped air extraction is adopted to make it high heat transfer efficiency, short drying period and realize automatic operation. The equipment has advantages of excellent drying performance and low running cost. It is mainly used for vacuum drying treatment of transformer and transformer with different capacity under 220kv, 110kv and 110kv.
