Compressed Air Challenge

A few of us in the engineering department are attending the Compressed Air Challenge today.  The Compressed Air Challenge is a seminar which highlights the operation and optimization of compressed air systems.  Being that those subjects go hand in hand with EXAIR products and practices, we hope to not only attend and learn, but to contribute, given the opportunity.

One of the subjects to be covered is the impact of different compressor controls.  Many compressors use feedback control systems to either throttle the amount of intake air supplied to the compressor (known as modulating system control or throttling), or to reduce the compressor displacement/speed to accommodate for system load ( known as variable displacement/variable speed control, respectively).

These optional control systems can save energy costs by responding in real time to the needs of the system.  For example, if a compressed air flow of 100 SCFM at 80 PSIG is required for 2 hours of the workday and after this initial use only 50 SCFM at 80 PSIG is required, a variable speed compressor can accommodate for this change by adjusting the speed of the electric motor driving the compressor.  In this example the motor speed will lessen and the required electrical demand to product the required compressed air will lessen as well.  All the while, maintaining adequate compressed air pressure and flow.  I’m looking forward to learning more about these feedback systems.  These control systems do the same thing as an EXAIR product, they optimize and save compressed air costs!

If you have any questions about your compressed air applications or how EXAIR can fit into your current system, give us a call.
