About us

Experience makes the difference

For more than 50 years, we – a medium-sized company – have been active on the market. Since we have been established in 1951 our portfolio of performance has been expanded and aligned again and again. Today, our customers benefit from this experience, i. e. all relevant technical questions will be answered proficiently.


Good quality at competitive prices

In 2010, the two product categories fittings and heat exchangers were separated from G.S. Anderson GmbH and integrated into Anthermo GmbH. For our long-standing customers in numerous industries (e. g. pipeline construction, petrochemistry, refrigeration technology, mechanical engineering) nothing has changed. They continue to trust to our proven reliability and flexibility. At that, our national and international suppliers provide for balanced cost effectiveness.


Individual solutions

For us, customer orientation means in the first place that we are able to offer more standard products. Upon special request, we also sell specially made components precisely matching to our customers’ demands. This is valid for fittings as well as heat exchangers.


Technical and expert know-how

All our staff has been working in this company for many years thus having the necessary know-how for qualified consultation. By means of internal and external trainings we always are state-of-the-art.
