Highly accurate material distribution guarantees that even WKH OLJKWHVW FRQWDLQHU PHHWV \RXU VSHFLȴFDWLRQV In many industrial applications, it is important for the compressed air to be as clean as possible. One example is the beverage industry. Franz Bunte went into the beverage trade in 1895. His business grew rapidly and he was soon well known across the region of eastern Westphalia. In 1932 Franz Bunte’s son-in-law Paul Gehring took over the business, which has since operated under the name Gehring- Bunte. After securing a licence in 1934 to make and sell Coca-Cola within a 30 km radius of its headquar- ters, Gehring-Bunte expanded into the beverage production business. The third generation assumed control of the family business in 1955, when Paul Gehring’s sons Dr Paul Gehring and Werner Gehring took the helm. They made the company what it is today: a leading seller of brand-name beverages. This success was built on Chris- tinen-Brunnen, a mineral water plant in Ummeln, Germany. The new company’s first bottle, labelled “Teu- toburger Mineralbrunnen”, left the production line on May 1, 1966. Today “Christinen” is among Germany’s most recognised mineral water brands and is also very popular across Europe. Since 1994, the company’s activities have been complemented by a bot- tling operation in the town of Wiesen- burg am Fläming in the state of Brandenburg and the products of the Erkrath mineral spring near Cologne. In 2011 Gehring-Bunte had a total output of 155m litres bottled in 300m containers by approximately 220 employees. Compressed air – food-grade and economical As an energy source and control medium, compressed air is used eve- rywhere in a bottling plant. However, these applications are subject to strin- gent air purity standards. A basic air supply is also needed for the boosters of the two PET bottle production lines. Consequently, when it came time to replace the entire compressed air system, it was clear from the outset: the new rotary screw compressors would have to be dry compression models. Moreover, the compressed air treatment equipment would have to ensure the necessary quality on a reliable basis. Compressed air stations often generate more compressed air than is actually used, as the end users’ requirements vary over the course of the day. As a result, there is often an imbalance between production and consumption. The best approach is therefore to start with an analysis of the actual needs and then to build a system based on the results. In 2011, Christinen-Brunnen bottled 155m litres of beverages in 300m containers.
