Energy-efficient steam extraction with condensate recovery.


Hardening is an energy-intensive process, with continuous cooling being performed on the electrical components, the inductors, the quenching water and the work pieces. Therefore, we pay particular attention to the degree of efficiency and ensuring that all components have an efficient design. In terms of the inductor energy sources, we rely on state-of-the-art technology such as TIV2-D converters that reduce energy consumption and enable precise process control. The use of highly-developed parallel oscillating circuits to promote energy transfer, short cable lengths and frequency-controlled pumps reduces the energy consumption of the system. Our tempering procedure using residual heat saves energy as no additional furnaces are required. Steam extraction with condensate recovery and closed quenching water circuits is provided as a matter of course, meaning that our hardening systems are some of the most energy-efficient in the world.

We use the latest converter technology to make optimum use of the electrical energy that is supplied.

Standardised recooling systems are used for the quenching media that cools the inductors and the electrical components.

A 'chiller' for independent coolant supply can be integrated into the hardening system.
