Control & business case3 min read
Your compressors. Working as one team.
Production changes pace. Your compressed air station should keep up. Discover when central control can help your compressors work better together.
When is central compressor control worthwhile?
01Which signs justify an assessment?
Frequent load/unload cycles, several large machines running at low demand or unstable network pressure are reasons to measure station behaviour. A production expansion or compressor replacement can also make the previous configuration unsuitable for the new demand profile.
02What does central control change?
Individual compressors retain their own machine and protection functions. Station control coordinates enable signals and required capacity within a shared pressure band. It considers the available machines and their operating ranges, aiming for a suitable combination with limited unnecessary idle running and acceptable switching cycles.
03Are variable-speed compressors enough?
Variable speed alone does not ensure an efficient combination. These machines also have minimum and maximum flow capacities. Poorly coordinated transitions can create inefficient states, so fixed and variable capacities need to be assessed together.
04How is the business case calculated?
Measure actual electrical power, machine states, pressure and, where possible, air flow over a representative period. Simulate an improved operating strategy for the same demand, then compare annual savings with control, interface, installation and commissioning costs. Simple payback is investment divided by annual net savings; changes in production and additional operating costs must be considered.
05When should other measures come first?
A single compressor, disconnected air networks or unsuitable machine capacities may require a different intervention. An audit also considers leaks, bottlenecks, pressure losses and air treatment. Measurements determine the order of improvements.
