Audits release the full potential of compressed air

Conducting a survey and taking measurements is useful when purchasing new compressors, for example. Energy savings also matter for the environmental impact of production facilities.

Our name for compressed air system audits is Syyni system analysis  AirAudit service for international customers). You should order a survey and analysis if your system is experiencing problems or you are planning a new compressor purchase or a larger renovation of your system or network. Compressed air takes energy to produce, so it is important to maintain the whole system. Our audit targets all components of the system – not just the new compressor’s installation, for example.

In the field, we have seen how the data measuring interval of compressed air systems is often too long, leading to an inaccurate impression of the system’s actual condition. Our audits measure checkpoint pressures every three seconds immediately after the compressor as well as before and after the dryer, if necessary. We install metering points in multiple parts of the network to pinpoint all problematic areas. We also measure the total output and electricity consumption of compressors. Expanded measurements also include the temperature of dryer intake air and the compressed air’s dew point. This gives us an extensive overall picture of the system and network performance, pressure level fluctuations, and potential pressure drop points.

Surveys are essential for older compressed air plants where parts of the network may be decades old with gradual additions.

The idea of an audit is for you to have an external party handle the survey, measurements and analysis of your system to produce versatile reports. The results may surprise you if your control system’s measuring interval is lax or inaccurate, for example. Diligent measurements also take time. In many cases, our measurements take at least a week, but we can collect data for up to a month, if desired.

The measurements alone are insufficient to make improvements. The audit reports summarise the key figures and illustrate them as charts and diagrams. Based on the results, we organise a review with the customer to assess total compressor output and configuration, pressure losses in the compressed air network and downstream processing, and the sufficiency of current tank capacity. For example, poorly configured compressors may waste energy due to running needlessly. In addition, excessive pressure settings will increase the need for maintenance.
