As someone with responsibility for the compressed air system, you will be expected to guarantee air at the right pressure and flow, but also at least cost. To do this there are two aspects: you need to produce and use compressed air as efficiently as possible. Disproportionate emphasis on efficient generation of compressed air in the compressor house, may lead to other factors such as the value of effective maintenance and user behaviour being overlooked. Here the role of maintenance in a reliable and energy efficient system.
Compressed air systems rely on effective maintenance for reliability, safety and energy efficiency and compliance with legislation. All of these contribute to a cost-effective compressed air system.
Missing a maintenance service is a false economy, for compressors, ancillary equipment and the distribution piping connections. Effective maintenance not only saves energy it helps address the more critical issue of air supply reliability for processes. For most operations reliability of supply (whether this be pressure, volume or air purity) is paramount. Although energy efficiency receives wide coverage, reliability of supply has even greater business implications, e.g. a metal products manufacturer had paid little attention to its compressed air system, stating that it only represented 4% of the site energy costs. However if the supply failed then the cost of lost production of a number of critical processes dwarfed the energy costs, so improving the system should have been a priority and delivered energy benefits as an added bonus.
