Energy consumption cut by more than half

Summary: Those who consider all components of compressed-air supply and coordinate them well will be able to generate compressed air in a very energy-efficient way even with strongly varying requirements. Walhalla-Kalk has set up a new central station, which requires less than half the energy previously required for the same amount of compressed air and, consequently, which will pay off quickly. This is due to the modern compressor technology including speed control and superimposed control as well as to the change between refrigeration drying and adsorption drying depending on the season.

1 Using the ­efficiency potential

Walter Fuchs has scored a hit with his concept of a completely new compressed-air station. The technician for mechanical engineering, who is responsible for project planning and maintenance at the Regensburg-based Walhalla Kalk GmbH & Co. KG, succeeded in reducing the energy consumption and, consequently, the costs as well, for com­pressed-air generation for the lime manufacturing plant by more than 50%. The plant manager Wolfgang Scheurer is more than satisfied with the result. Previously four stations, spread out over the works area, supplied the compressed...
