Get the most out of your compressed air system

Are you wasting energy because of an out of tune air system? Our central controller orchestrates your compressed air system for optimal efficiency and energy savings


Save energy

Master controllers save energy by making your compressors work together efficiently and ensure a stable pressure. All types and brands of machines can be controlled: fixed speed, VSD and centrifugal compressors and blowers as well.

Increase uptime

With our master controllers, the load will be distributed evenly among your equipment, hence equalizing the wear. Furthermore, compressors and blowers operating with our master have less load/unload cycles and operate at the lowest possible pressure/flow, to extended the lifetime of your machines.

Stay Connected

Management of facilities always involves remote monitoring, so machines should be able to send information which can be analyzed and used for improvement. This is only possible if your machines are connected: our master controllers ensure maximum connectivity, through Local Area Network (LAN) or via a cloud-based monitoring system.

What if I run multiple compressors without a central controller?

Without our central controllers, the load/unload pressure of each compressor must be set to react to changes in air demand. If the system pressure drops, an additional compressor will switch to loaded running. However, the sequence will always be the same, and this leads to a higher pressure than required (the higher the pressure, the higher the energy cost). Furthermore, the advantages of VSD or centrifugal machines are not fully used.

What about load distribution of my compressors?

Our central controllers can be set to prevent unequal wear of compressors, equalizing the running hours on multiple machines for more efficient service scheduling and reduced cost. Moreover, VSD and centrifugal units will run at the optimum point whenever possible.

Let Master Controllers optimize your compressed air system

It's all about efficiency, reliability and connectivity. Our devices can:

  • Optimize the operation of your compressed air and blower system in accordance with ISO50001, while pressure and flow setpoints are being met.
  • Maximize energy savings and keep the equipment in good maintenance condition.
  • Monitor your equipment for a proactive approach to maintenance, for live data visualization and for energy savings KPI accounting.
