The fourth updated and expanded edition of the Compressed Air Handbook contains recommendations and guidelines developed by specialists from various fields of compressed air technology for the design of optimized compressed air systems. The proven structure of the book, organized into the topics of generation, treatment, and distribution, has been maintained, and the content of each chapter has been brought up to date with the latest technology. Additionally, an introductory chapter on the energy significance of compressed air generation in EU countries has been included, which also describes energy and cost-saving potentials, their realization, and utilization. Another thematic focus of the Compressed Air Handbook is the sizing and planning of compressor stations, treatment systems, compressed air distribution, control, and regulation systems – and for good reason: especially in their interaction.
