 Description of variable-pressure vacuum transformer coil drying oven:

This kind of variable-pressure vacuum transformer coil drying oven adopts variable-pressure drying principle suggested by Dr. Moll from Germany, specialized for drying transformer bodies. Comparing to conventional vacuum hot air cycling method, drying cycle of this variable-pressure type has been saved about 30-45%.

Main features of variable-pressure vacuum transformer coil drying oven:

 1) Compact structure, small occupation

 2) Heating system is controlled by power control module, assuring 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 reduces actual heating power very much.

 3) PLC control, more stable and reliable

 4) Special baffle valves for vacuum drying, better vacuuming performance
