Energy balancing in utility and supply processes at the Krombacher Brewery, GermanyInternal energy balancing is an important instrument used by many breweries to determine the leading consumers throughout the entire brewing processes. In the plants, necessary energies such as heating water, steam and air are typically provided without exact knowledge of where and in what quantity they will be required. Virtually every production operation has a compressed air network but only rarely are those networks monitored and adapted to reflect actual consumption rates. Costs can easily be reduced if the compressors used to provide the compressed air can be controlled in keeping with consumption.
