Vacuum Drying System, for Rechargeable Battery's Manufacturing Process (Multi-step Volume), DPB530

Vacuum Drying System, for Rechargeable Battery's Manufacturing Process (Multi-step Volume)

DPB530

Vacuum drying is performed during a rechargeable battery manufacturing process to remove water content from work pieces. In this system, chambers are stacked in multiple stages and many kinds of work pieces can be processed under different conditions.

Allows reduction of conductance in the vacuum exhaust route and installation of a high performance exhaust pump
Designed to support a pressure of 1 Pa or less
Hot plate system to enable high speed temperature increase
Required number of units may be stacked in multiple stages and processed under different conditions.
Hot plate (±2deg.C) improves the temperature distribution accuracy in chamber.
Thermocouples are equipped with in the chambers as standard to monitor work piece temperatures. (Thermocouples may be increased as necessary)
Variable chamber sizes are available depending on the work piece sizes (upon request).
