Compressed air: Find the leaks, lower the pressure, and measure the results

Create "good practices" around continuous monitoring of system leaks


Monitoring of your compressed air system usage is a great first step to identify where your issues might be. Courtesy: Ingersoll RandCompanies often face the challenge of identifying best practices for compressed air energy conservation by assessing the value others have realized while putting best practices into action. Without fail, every month brings an assortment of technical epiphanies, attempting to inspire the compressed air consumer with an audit expert’s secrets to success.

As an organization, Ingersoll Rand has audited thousands of systems worldwide. We routinely work with multinational companies to develop and execute strategies designed to deliver energy savings while simultaneously improving operational quality, reliability, and productivity. Leveraging this experience and associated results, we have identified what appears to be the “best” compressed air best practice of all.

For the purpose of ranking the quality or significance of any product or service, it is common to use a good, better, best segmentation. With this as a guide, some easy-to-execute energy conservation measures that may be considered good practices warrant consideration. By redefining these common practices as “good practices,” what is arguably the “best” best practice can be articulated without the redundant abuse of the word “best.” 

Find the leaks

The first “good practice” is an obvious one: reduce the quantity of compressed air associated with leaks. This is an energy conservation measure that is usually executed by an organization without having to enlist the services of a specialized service provider. In theory, this should be easy because fixing a leak does not require specialized skills or capital expenditure.

Ultrasonic leak detection equipment has been readily available for years, and many organizations have purchased the tools required to easily locate compressed air leaks of all sizes during normal production periods. This technology allows an operator to hone in on the specific acoustic characteristics of a compressed air leak and filter out all surrounding production noise. This has made finding leaks easy, but unfortunately finding a leak does not impact the energy required to support a compressed air system.
