The first step in understanding your compressed air requirements is to undergo a compressed air audit. Here, meaningful and accurate performance data should be gathered from your existing compressed air system. This is most effectively carried out by attaching a data logger to your compressed air system for a set period of time (usually a minimum of 7 days). This collects data which can then be uploaded and analysed using proprietary software. Based on the resulting air consumption profiles, tailored system upgrade or improvement recommendations can then be made.
When it comes to selecting who will perform and analyse the results of a compressed air audit, you will find that there are numerous providers. If you look a little closer at even 2 or 3 providers, you will also find that there can be big differences in what the service provision includes and how much it costs. So, how do you determine which provider is right for you? We think there are three key factors you should evaluate when it comes to selecting a compressed air audit provider;
- Under pressure
One area that you should not compromise on is the logging of pressure. This is one of the most important indicators of the overall condition and control of the existing station and can provide valuable information in determining sizing recommendations. Unfortunately, this key audit component is often what we see missing in audit reports prepared by some providers.
- To pay or not to pay. That is the question. But what is the answer?
You will also want to consider the cost of undergoing a compressed air audit. While some providers may offer this free of charge others will charge for this service. You should be careful to compare the content of such audits as there may well be a large difference. Unfortunately as they say, there is no such thing as a free lunch! If you want value and an audit report with substance, then you should expect to pay for this service.
- Complying with uniform standards
Finally, it's worth noting whether the provider’s measurement and evaluation methods comply with ISO 11011. This standard sets out the requirements for conducting a compressed air energy efficiency assessment as well as analysing and reporting the results.
Conclusion: Make sure you’re comparing ‘apples with apples’
The recommendations that can come from undergoing a compressed air audit can have a large and defining impact on what changes you decide to make to your compressed air system. And this will no doubt therefore have cost and performance implications. So, in the end, when it comes to selecting a compressed air audit provider, you should make sure you are comparing ‘apples with apples’, just as you would if you were obtaining capital equipment quotes.
