Induction Heat Treatment Equipment

Induction Heating generates exactly the desired amount of heat , prescisely in the place where it is required. It can be applied to virtually any part of a metal component without affecting the body. Heating of the selected zone is more rapid and controllable than any other method.

Megatherm Induction Hardening equipment is available to heat treat many components

Standard Heat treatment units available

  • On line head hardening of Railway track rails with continuous straightening.
  • Vertical scanners in single and twin spindle, Horizontal scanners, Component Lift and Rotate Index Table, Shuttle Tables, customized Induction hardening machines Power supply : 50-500kw . Frequency :1, 3, 10, 30 and 200kHz

SiC Weld and SiCTREAT

The most precise and rugged Radio Frequency Induction Heating System, offered by Megatherm.

The name SiCTREAT relates to Silicon Carbide Field Effect Transistor or SiCFET – the most robust & efficient high frequency switching device, available in todays Power Semiconductor World. Built in load tuning capacitors & variable ratio impedance matching transformer and a powerful visual guidance available on PLC Touch Screen empowers you to quickly achieve your heat treating power & frequency at ease to suit a broad range of work piece.


The ultralow switching losses of SiCFET enables to achieve power supply efficiency to 99% at 300 KHz, together with high efficient Ferrite core output matching transformer, SiCTREAT system offers the best energy saving unparalleled in the market.

Compact Design

The SiCFET switch assemblies together with robust drivers, intelligent FPGA controllers and water cooled heat sinks are integrated into a compact module with control interface to PLC, Power interface to DC / 3 Phase mains and the RF output.

PLC / CNC Controlled Operation

All controls necessary for heat treatment operation can be built into the SICTREAT. This includes digital meters for voltage, frequency, current/power, and LED indicators. The mechanical operations are guided by either a PLC or a CNC as per choice of the customer.
