Electric Heating Elements

Electric heating elements are used wherever heat needs to be generated or precisely and efficiently dissipated. They are an indispensable component of modern industrial and manufacturing processes – from mechanical and plant engineering to building technology, as well as the food and packaging industry, plastics processing, and the medical, energy, and electrical engineering sectors. Everywhere, they ensure reliable temperature and energy control, guarantee stable process conditions, and contribute significantly to quality, efficiency, and process safety.

The KRAH Group offers a wide range of electric heating elements and customized heating solutions. Whether as a single component or a complete assembly, we develop products that meet the highest standards of efficiency, reliability, and service life. Our heating elements are used both for heat generation and for the controlled conversion and dissipation of electrical energy, for example in heating applications or as damping or braking resistors. Together with our customers, we create tailored solutions for industrial processes, equipment, and systems worldwide.
