This series of vacuum drying oven is specially designed for the production process of lithium battery industry. The temperature range, the degree of vacuum, and the size of the working room and the height of the interlayer all meet the needs of the lithium battery industry to the greatest extent. There are three chambers in total, each of which is independently controlled, with independent temperature control and no interference with each other.
