GBF1700RHP4 Rapid Hot Pellet Press in Glovebox with 1600°C Inductive Heating and 100 MPa Pressing Force
The GBF1700RHP4 is engineered for precise pellet pressing tasks requiring high temperature and controlled atmosphere conditions. It operates inside a glovebox with a gas purification system maintaining oxygen and moisture levels below 1 ppm, ideal for sensitive materials. This system enables rapid inductive heating of samples up to 1600°C at approximately 1°C per second, combined with pressing forces up to 100 MPa using a 5-ton motorized electric press.
After pressing, the sample and graphite die are rapidly cooled by water-cooled copper clamps, achieving cooling rates up to 10°C per second. The integrated digital PID temperature controller supports programmable heating, dwelling, and cooling segments with temperature accuracy of ±5°C. The system includes all necessary feedthroughs for power, thermocouples, induction coils, and communication within the glovebox environment.

Hinweise zur Konfiguration und zum Betrieb
The GBF1700RHP4 includes the glovebox with integrated gas purification, induction heating system, motorized pellet press, and digital control panel. Water cooling is essential for the induction coils and copper clamps; optional chillers are recommended for stable long-term operation. On-site installation is required for both the glovebox and hot press. Users should ensure proper gas supply and water cooling parameters are met for safe and effective operation.
