Induction Hardening Systems

PSTEK’s induction heating system for heat treating regulates frequencies and power output in optimum states through a regulation system it has independently developed, ensuring top-quality heat treating. The system uses the newest IGBT and MOSFET to enable 4,500 kW and at least 800 kHz (MHz) power supplies.

At PSTEK, we use our competence in electromagnetic field computer analysis and decades of various heat treating applications to suggest and provide optimum supplies and device configurations based on customer demands and conditions.

Features & Benefits
