Voith Paper installs a new vacuum system to Dresden Papier in Heidenau, Germany

Feb 17, 2011. /Lesprom Network/. Dresden Papier commissioned Voith Paper to install a new vacuum system for the wire and press sections of its PM 4 in Heidenau, Germany, as the company said in a press release received by Lesprom Network. Dresden Papier based its investment decision on an extensive pre-engineering of the existing vacuum system and a balancing of the entire PM and building ventilation technology. The paper mill wanted to record and implement both the economy and the energy saving potential. The examination was performed by Voith Paper. The overall concept was decisive for receiving this order, taking account of future rebuild stages to achieve an optimal PM energy balance step by step. A vacuum blower system ensures high thermodynamic efficiency, allowing at the same time power input depending on the air requirements at the paper machine. The hot exhaust air produced can be used for hood supply-air heating through heat exchangers to reduce steam consumption there. Another important aspect in terms of environmental protection is the fact that this technology does not consume any fresh water as conventional systems do. Hence, operating costs are also decreased, and maintenance is optimized due to the reduced number of vacuum generators. At present, the PM 4 in Heidenau produces 45,000 tons per year of coated and uncoated wallpaper base and the mill is thus the world's largest producer in this product segment. Dresden Papier GmbH is a subsidiary of the Canadian Fortress Paper, Ltd. Voith Paper is a division of the Voith Group and the leading partner to and pioneer in the paper industry. Voith Paper is optimizing the paper manufacturing process, focusing on developing resource-saving products to reduce the use of energy, water, and fibers.
