Equipment Introduction;
The multi-layer battery vacuum oven has a stainless steel inner pot and can work independently. The heating, vacuuming, and nitrogen filling modes are automatic circulation, and the time for each working stage is set through the touch screen. The vacuum oven adopts a PLC control system and touch screen operation, with short heating time, fast heat dissipation time, and good pressure holding effect. The heating methods are thermal radiation and thermal conduction
Equipment function:
