Coating technology since 1903
KROENERT GmbH & Co KG is a Hamburg-based machinery manufacturer that develops and produces custom-engineered coating, printing and laminating systems for web materials. The product range includes high-performance production systems (RECO), compact laboratory and pilot systems (LABCO), modular production systems (MCO 5000), inline coating systems for film stretching lines (INCO) and product lines for prepreg manufacturing (EPCO). Materials processed include paper, films, aluminum, glass and carbon fibers, membranes, nonwovens and textiles, using over 60 application methods, working widths up to 3,800 mm and speeds exceeding 1,000 m/min. Customer industries include technical products, paper finishing, packaging, composites, membranes, printed electronics, renewable energies as well as medical and pharmaceutical applications. The Hamburg site portfolio is complemented by a Technology Center with test systems as well as retrofit, maintenance and service offerings. Founded in 1903 as a manufacturer of wallpaper printing machines, the group belongs to Altonaer Technologie Holding GmbH (ATH).
