Features:

1. Circulation with strong convection, vacuum purge, combination of cooling water and cooling gas, short cycle and high efficiency.
2. Good temperature uniformity. The performance of treated materials is equalized.
3. The joint part is made in PPM sealing structure, which keeps the furnace gas stable and prevents hydrogen or other protection gas from mixing with air.
4. The temperature is controlled by thyristor of intelligent instrument, which may automatically complete the rise or fall or maintenance of temperature. All operations are controlled by programs and stored and recorded automatically.
