Andritz Fiedler history Fiedler was founded in 1889 as a company for punched plates, mainly used in agriculture, breweries and mills for feed and food industry for general plant production and engineering. Fiedler specialized in producing perforated materials as drilled and milled components for pulp and paper-, food- and other industries. This led the company to a leadership position worldwide. In the 90ies Fiedler developed different screen basket and rotor types, respectively complete screens for pulp and paper industry. Strainers for power plants, plant engineering and pump manufacturers. In September 2003 the acquisition of Fiedler by Andritz (a former customer) was completed. 8 Individual footer (e.g. title of presentation, date, name of presenter): Arial 9 pt, gray, align center, max. 1 line
