About Fritz Althoff
Fritz Althoff GmbH & Co. KG is a third-generation family business from Bad Oeynhausen in East Westphalia that has been manufacturing high-quality products and system components for almost 90 years. The portfolio covers plant engineering and sterile technology for biochemistry and pharmaceuticals in accordance with cGMP, as well as quick-release, camlock, tank and dry couplings, valves, sight glasses, strainers and sampling valves. Product-contact materials are stainless steels such as 1.4404, 1.4435 and 1.4529, as well as Hastelloy, titanium and FDA-compliant plastics including PP, PTFE and PEEK (partly USP Class VI). The in-house manufacturing depth ranges from CAD design and mechanical production through TÜV-certified welding to electropolishing with surface qualities down to Ra ≤ 0.05 µm. Customer industries include the chemical/biochemical industry, pharmaceuticals, the food and beverage industry, laboratory/medical technology (including dialysis technology) and environmental engineering.
