Passion, Zeal and Continuity

Since 1932, high-quality products of electric heating technology are our strength. As one of the leading manufacturers in our industry, we find real solutions for our customers and set new standards for products of the highest quality and efficiency.

This down to earth attitude has been the solid foundation for the on-going growth of our group of companies which is still owned by the family 3 generations later. And so, from a small company in 1932 in the form of the founding company Ihne & Tesch as well as Keller, Ihne & Tesch, a worldwide supplier of electrical heating technology located in Germany, Austria, France and Great Britain has emerged.

Part of the family

As a family-owned group of companies ethical values are at the root of our work. You will definitely not find any pretty-sounding statements of company philosophy hanging ignored on the wall. We actually live what a lot of other people just talk about. We can quite rightly say that we are part of the family to our employees – a dedicated community which creates solutions with great passion.
