Their business activity is focused on offering the market professional products at the top end of the quality scale for soldering/brazing and other heating jobs.

Sievert AB is a world leading manufacturer specializing in high-quality heating tools for professionals. Their products represent today’s most advanced technology. Their goal is to develop, manufacture and supply innovative and high-quality tools for all types of soldering, brazing and heating applications.

They have been in business for more than 130 years, and today they are a world leader. But still their work has only just begun. Carl Richard Nyberg was a specialist in soldering, but he felt that the soldering technology available in the 1880´s could be greatly improved. He was determined to find a heating source that was more efficient. After much experimentation he succeeded in finding a solution, and in 1882 he made the first prototype of a soldering blowtorch for which he also obtained a patent.

That same year the future industrialist, Max Sievert, opened the doors of a machinery business in Stockholm that would form the foundation of a major company. When the paths of Nyberg and Sievert later crossed, they formed a partnership that was uncommonly fruitful. Nyberg manufactured blowtorches, and Sievert sold them throughout the world. A successful business was launched.

Since 2003, Sievert is a member of the Rothenberger group of companies.
