Danotherm
Design and manufacture of highly reliable power resistors for the most demanding industrial applications.
Over a century solving electrical challenges
The company was founded in 1919 by S. Samulewitz in Frederiksberg (Denmark), driven by a passion for electrical engineering and for solving its customers' real problems. More than a hundred years later, Danotherm continues to design and manufacture in Europe for customers all over the world.

The Danotherm way
Danotherm's engineering team analyses the real conditions of each electrical system and defines the safest and most reliable solution. When no product meets the requirements, a specific one is developed.
How we work
Three principles that guide every project.
Aim for the moon
To make an impact you have to act. We try new things without fearing failure: it is the only way to do it better.
Customer First
The customer is the priority. Every decision in the process is made with the problem to solve in mind.
Stay in the know
We are always looking for new ways to improve, with the goal of exceeding expectations on every project.
