Strong through tradition and innovation
The name Fritzmeier For decades, it has stood for expertise and pioneering spirit in plastics and automotive technology. As early as the 1970s, Fritzmeier made a name for himself as an innovator: The first all-plastic skis contributed to Rosi Mittermaier's triple Olympic victory, followed by the founding of the cult brand in 1977 mistral, whose boards led surfing legend Robby Naish to 15 world championship titles.
This know-how in plastics technology has been the basis of Fritzmeier's environmental technology activities under the brand since 2012 COALSI — specializes in innovative odour prevention solutions.
The next logical step followed in 2025:
With the founding of coalsi GmbH The successful brand became an independent company. This strengthens our position as a specialist in odour protection and foreign water solutions and enables us to react even more flexibly to the requirements of our customers.
The COALSI odour filters are used wherever there is a nuisance of odors. Smells impair well-being, impair concentration and can even be harmful to health. Due to fermentation, rotting or decomposition, unpleasant odors from sewer shafts, pump and collection shafts, silo or roof vents are a real problem in many places.
The COALSI hybrid activated carbon filters have been specially developed to permanently eliminate these odors and the associated nuisances and dangers. In contrast to conventional activated carbon filters, the effectiveness of COALSI odour filters is significantly improved by innovative hybrid technology combined with high-quality and handy components. This makes COALSI an effective odour barrier.
In doing so, we strive for a sustainable partnership with municipalities and industry. The focus is not on the product, but on holistic solutions. For a better quality of life and a livable environment.
