TVK-S Series

The profitable, efficient and flexible TVK-S range is the smallest in the family of compact vertical TVK machines. The processing area, control components, power systems and cooling systems are combined into one single system, which minimizes the surface area required on the ground, with enough space to easily carry out operations and maintenance.

TVK-S machines adapt to different applications, from tempering, hardening and annealing to brazing. The max power is 100 kW and between 10 kHz and 300 kHz. Three different models are designed for specific part lengths:


TVK-S machines offer the benefits of maximum flexibility, optimum investment, and easy installation:

TVT Series

Our TVT type vertical induction hardening installations offer great versatility in processing parts of varying dimensions and characteristics. Hardening can be accomplished by scanning or single shot, with or without rotation.

The typical installation includes a transithermic® induction heating power supply; cooling system for the power supply; cooling system for the hardening liquid; CNC for the inductor shift; and TVT handling machine.

The installation shown at right is designed to harden axles up to 2000mm in length and 250kg in weight. In this particular case, it is equipped with a 300kW generator running at frequencies from 3 to 10kHz.

TVG Series

Our versatile TVG vertical induction hardening installations accomodate parts up to 3000mm in length, 4000mm in diameter, and weighing up to 2 tons. This is a manual load/unload system in which the inductor moves along the part.

The typical TVG installation includes a transithermic induction heating power supply, an inductor moving numerical control system, and TVG handling machine.
