How to reduce operating costs with a compressor audit

Energy consumption accounts for up to 70% of the lifecycle cost of a compressed air installation. With the increase and the general uncertainty about energy prices it’s better to lower consumption as soon as possible.
An important question these days is how can we reduce the environmental impact of our company and lower operating costs? Nobody still needs to be convinced that we need to save energy and many companies have clear targets to reduce their energy consumption.
In this article we will explain to you how to reduce the operating costs. Is it time to buy a more modern compressor? Or to replace the piping system? It all starts with an air compressor audit.

Every compressed air installation can be improved!

In most compressed air installations, there are many possibilities to save energy and very often they are unnoticed.

  • Leakages: Compressed air installation of more than 5 years old has on average 20% of air leakages.
  • Unloaded hours: Air compressors running unloaded consume on average 25% of their total power.
  • Pressure band: Reduction of 1 bar net pressure results in 7% energy savings.
  • Latest technology:Motor exchange can bring you up to 2% additional energy savings.
  • Energy recovery:Use the heat of your air compressor to generate hot water. Compressors running at full load (24/7) will give you on average 80% of energy savings.
The most proactive and efficient way to minimize operational costs is conducting a compressor room audit like AIRScan.

How does AIRScan work?

AIRScan is one of our tailor-made solutions which is fully consistent with your operating budget and can range from a basic to a full compressor inspection. The advantage of AIRScan is that there is no need to interrupt the production because the audit runs while the compressors are operational. Atlas Copco’s energy consultants determine an acceptable operating balance to satisfy production needs and minimize operational running costs. The logged information is evaluated via our in-house audit software, which can simulate various configurations of compressed air installation. The received information is interpreted and presented in a detailed compiled report that includes:

  • Cost & return analysis
  • Measurements insight 
  • Optimization recommendations

An AIRScan report provides a clear summary for decision-makers, as well as an in-depth evaluation of problems and solutions for technical people. This allows us to provide realistic projections on potential energy savings, as well as environmental benefits.
