Vacuum Drying System for Rechargeable Battery's, DPB430

Vacuum Drying System for Rechargeable Battery's Manufacturing Process

DPB430

Vacuum drying is performed during a rechargeable battery manufacturing process to remove water content from work pieces. This vacuum drying system has a high speed exhaust function, high speed heating function, a quick cooling function, high temperature distribution accuracy, work piece temperature monitor terminal, and a vacuum profiling mechanism in order to reduce process time and to improve process yield.

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
Improved temperature distribution accuracy within the chamber thanks to the employment of a high temperature distribution accuracy (±2deg.C) hot plate
Equipped with five thermocouples in the chamber as standard to monitor a work piece temperature
Touch panel operation
Vacuum control is possible to execute vacuum profiling (optional)
Ports are equipped with a current introduction terminal and thermocouple introduction terminal as standard to allow installation of heater plates separately inside (introduction terminals are optional).
Supports installation of a vacuum blower fan or an external air introduction unit to reduce time of temperature increase and decrease in atmosphere and improve temperature distribution (supports separately for specific item).
