BETEX MF-GENERATOR3.1-22kW-400V medium frequency induction

BETEX MF-GENERATOR3.1-22kW-400V delivers controlled induction heating and cooling for metal workpieces. A 7-inch touchscreen shows setpoints and actual values, plus a live heating curve and heat log. The generator outputs 22 kW at 10 to 25 kHz and measures temperature with type K thermocouples up to 300°C. ΔT monitoring uses two sensors to limit temperature differences and reduce material stress.

USB logging exports CSV or PDF, while optional networking links up to ten generators. Sequence mode runs five programmable steps for complex cycles.

for controlled induction heating

BETEX MF-GENERATOR3.1-22kW-400V targets mounting and dismounting tasks on metal parts. It supports ferrous metals such as steel and stainless steel. It also supports titanium and certain bronze alloys. You control power, temperature, time, speed, and sequences from the touchscreen.

This generator needs a connected fixed or flexible inductor. The system will not run without an inductor connection. Choose the inductor based on workpiece geometry and access.

Touchscreen control and heating modes

The 7-inch touchscreen provides setpoint entry and live feedback. It shows temperature and time as setpoint and actual values. It shows power and frequency as actual values. The screen also supports a heating curve display.

The system supports multiple heating modes, including temperature, time, and speed-based control. It also supports a temperature hold function with a configurable hold time. You can set hold time from 1 to 480 minutes.

Controlled cooling and sequence mode

The MF-GENERATOR3.1 adds controlled cooling with an adjustable temperature-time profile. It monitors workpiece temperature throughout the cooling process. If cooling runs faster than the set rate, the system adds heat to slow the drop.

Sequence mode runs five programmable steps in a defined order. Steps include temperature, temperature with speed, and pause. You place one or more sensors on the workpiece during sequence mode. Network operation excludes sequence mode.

ΔT monitoring with two sensors

ΔT monitoring uses sensors T1 and T2 to track temperature difference across the workpiece. T1 acts as the main sensor and controls the process. When ΔT exceeds the configured limit, the system pauses heating. This supports applications where temperature gradients matter.

Data logging, USB, and networking

USB supports data logging and firmware updates. Logging can export files for reporting and traceability. The system supports network communication between multiple generators. One generator logs when you couple generators. The log setup appears on the generator where you press START.
