In the 60s Linnhoff developed the Screen Drum concept for Asphalt Plants, a unique and pa- tented technology which eliminated the use of the hot elevator and vibrating screen associa- ted with conventional Asphalt Batching Plants. This concept reduced overall operating costs by not only reducing plant maintenance but fuel LINSTAL Factory Poland consumption as well. Since then a number of Screen Drum patents have been established. By August 1970, Klaus Thesenitz, the grandson of Eduard Linnhoff took over the company and renamed it Linnhoff & Thesenitz. 3 LINTEC Factory Buxtehude CSD 2500 – Hungary 4 CSD 3000 – Poland Containerized Asphalt Batching Plants CSD1500 – Buxtehude, Germany LINTEC Containerized Asphalt Batching Plants offer many advantages com- Containerized batching plants – the key to ease of pared to standard Asphalt Mixing Plants.
