The principle of kerosene gas-phase drying is to use kerosene with higher gasification point than water as the medium to bring out the water in the dried product, so as to achieve the purpose of drying the dried product. The main components of kerosene gas phase drying equipment include: Kerosene steam generation system, kerosene steam condensation system, kerosene condensate recovery system, vacuum pump unit, transformer oil tank and automatic control system.

In the actual drying process, many problems such as poor thermal conductivity of the vacuum tank are found. Now, the kerosene gas-phase drying equipment is improved to meet the needs of actual production.

Kerosene gas phase drying equipment manufacturers with the rapid development of China's power industry, the use of high-voltage transformers is more and more widely, and the demand is also increasing day by day. Transformer manufacturers are also constantly adjusting the product structure, and the voltage level is gradually increased from the initial 10kV to 220kV. As a necessary equipment for high-voltage transformer drying, the demand for kerosene gas-phase drying equipment is also growing in recent years.

Compared with traditional drying equipment, no gas-phase drying equipment has many advantages, such as uniform heating of transformer, fast heating speed, cleaning of transformer body, good drying effect and so on. However, in the actual drying process, there are still many deficiencies in kerosene gas-phase drying equipment, which need to be improved to a certain extent.
