Induction. Heating. Solutions.

Welcome to HIMMELWERK, the specialist for high- and medium-frequencies converters for inductive and capacitive heating. With decades of experience in the art of induction and customers from all over the world we can offer you individuell solutions based on our wide range of products.
HIMMELWERK has created a range of products with capacities ranging from 2 to 250 kW that meets countless requirements when it comes to inductive heating with high and medium-frequency converters.

Inductive heating describes the warming process of an electrically conducting workpiece through a magnetic field. Unlike other heating methods, inductive heating does not convey temperatur from the outside, but generates the heat in the workpiece itself. This offers numerous advantages.

The in the workpiece generated temperature results in a high degree of efficiency, as heat is only used where it is really needed. Furthermore, the thermal effect can be limited locally and in terms of the time involved. This leads to exact reproducibility of the heating pattern during mass production and, consequently, uniformly consistent workpiece quality.
Chemical/metallurgical reactions and impairments of the surface can be broadly avoided. Moreover, induction heating systems do not require start-up or warm-up times, but are ready for immediate use at all times. Heat development is limited to a minimum, reducing the exposure of operating personnel and the surroundings to any heat released. Induction heating systems can therefore be installed where production requires them. Unnecessary transportation is avoided as a result. Induction heating systems provide optimum prerequisites for the automation of heating processes.
They can be easily adapted to suit existing machinery and facilitate the construction of practical fixtures. Their use saves the deployment of skilled workers. These systems are particularly ideal for serial production. Use of these systems is also practical in many cases where small production quantities are involved.Mass production and the manufacture of small series can therefore be rationalised, not only in terms of efficiency, but also the improvement of product quality.The various range of applications does not only include heating for conventional processes like forging, soldering or melting. For example, inductive systems can also accelerate drying of paints and hardening of adhesives applied to metals.
