TÜV SÜD confirmed to Festo AG that the company's "Energy Saving Services" scheme is a suitable and qualified method for the analysis of compressed-air systems.
Many compressed-air systems used in the manufacturing industry offer the opportunity of saving up to 60 per cent of operating costs. Esslingen-based Festo AG & Co.KG developed a method which enables reliable analysis and evaluation of the energy and cost-efficiency of these systems to be performed. The company, a market leader in pneumatic solutions for process and factory automation, commissioned TÜV SÜD to verify its methodological approach.
TÜV SÜD's assessment of the "Festo Energy Saving Services" method was based on an audit standard that comprises elements from various standards, including ISO/DIS 11011 and the EN 15900 "Energy efficiency services", VDI 3922 "Energy consulting for industry and business" and EN 16247 "Energy audits" standards.
Modular approach: audit, engineering, implementation, maintenance
Specifically, Festo's service technicians examine the compressed-air systems at their clients' companies, taking into account aspects such as the production, consumption and quality of compressed air, but also detection and elimination of leakage. In addition, they also look at the efficiency of the connected consumers. With the help of various tools, including questionnaires, audits and on-site measurements, the experts then collect the data for the evaluation of the compressed-air system.
The audit carried out by TÜV SÜD's impartial experts revealed that the "Festo Energy Saving Services" scheme ensures methodologically correct analysis and evaluation of the energy efficiency of compressed-air systems. "The company's training programme and intensive training courses within the scope of "Festo Didactic" provide employees with all the qualifications they need to conduct a compressed-air energy efficiency audit in compliance with the standard", says Dr Michael Bunk, Head of the Energy Systems department at TÜV SÜD Industrie Service in Dresden. Analysis of the compressed-air systems further supplies important information for maintenance, modernisation and the planning of new systems.
"In industry, compressed air is an important energy carrier that should be used as efficiently as possible. Our objective is to ensure that our clients bring out the maximum energy and cost efficiency in their compressed-air systems", says Sven Lensdorf, Head of the Service Management department at Festo. "The successful assessment of our service performance by TÜV SÜD shows that we actually live up to this ideal."
