Vacuum Drying Furnace

This vacuum drying furnace adopts variable-pressure drying principle suggested by Dr. Moll from Germany, which is specialized for drying transformer bodies. Compared with conventional vacuum heating drying methods, the variable pressure type can save up to 30-45% drying duration.

Main Features

• Compact structure, small size
• Heating system is controlled by power control module, ensuring even and stable temperature. Real power consumption during temperature-keeping is only about 35% of total power. There is no fluctuation of heating load and thus greatly reduces actual heating power.
• PLC control, more stable and reliable
• Special baffle valves for vacuum drying, better vacuuming performance
