Vacuum Degree


Temperature Rise Rate

Temperature Rise Rate Can Be Modify(30/min | 1/h, Company Suggest 10-20/min.

Pressure Protection

The system is specially made to prevent the danger of closure   of the exhaust port, the blockage of the exhaust port and the excessive   pressure of the furnace tube. The signal is obtained by the electric contact   pressure meter or pressure sensor then the drive control module will close   the electromagnetic inlet valve and starts the electromagnetic exhaust valve   and the alarm. to ensure the furnace can be used properly and safely.
