Only development makes us who we are.



Krantz looks back at a long and eventful history. Already at the beginning we utilized customer proximity and specific customer solutions, and still continue to do so until the present day.

In 1882, engineer Hermann Krantz founded the enterprise in Aachen. About 40 years later, in the 1920s, Krantz mainly focused on two core areas. First, the specialization on high-temperature water heating. Second, the sale of components for air distribution systems in the textile industry.

Krantz goes global

The next important milestone in the history of Krantz took place in the 50s. Back then, the first components of air distribution systems for the nuclear industry were distributed. The internationalization occurred in the 70s, when Krantz America Inc. in Charlotte (North Carolina) was founded. At the same time Krantz already hold 400 patents for components and air distribution systems, establishing itself as market leader.

Expansion of Clean Air Solutions

One decade later, in the 1980s, the first thermal oxidizer is being delivered. Further internationalization is also actively pursued in the 90s, for example by signing a large-scale contract for the Airport in Athens (Greece).

Continued development

After the turn of the millennium and a social focus on pandemic research, the development and distribution of special filters for laboratories with the highest safety class BSL3 and BSL4 in Hong Kong followed. Krantz also invested into its own further development. In 2009, the in-house Research- and Development Center is being completed. Six years later, in 2015, the Space for Innovation opens to the public. It is a permanent exhibition that conveys the specialties of both Krantz products and services, all shown through the usage of concrete examples.


During the more than 130-year corporate history, Krantz changed its name over two dozen times, until the brand finally became a part of the STEAG Corporation in 2018. Since that date, there is a strong interconnectedness between STEAG and Krantz.
