Businesses are struggling to cope with compounding costs and rising energy bills, that much is clear. In the face of surging costs and the absence of certainty, businesses across the globe are looking to reduce consumption and cut costs wherever possible.
In this new (increasingly costly) reality, acoustic imaging is offering manufacturers a crucial lifeline; it is helping energy-intensive industries to keep the lights on by driving down operating costs and slashing maintenance expenses. Users have heard of ‘lossless sound’. Well, acoustic imaging takes that quite literally.
Detecting previously undiscovered air leaks
For the UK and much of the EU, the cost of energy has almost doubled from 2023 to 2021, with prices at 34.0p/kWh (versus just 18.9p/kWh in 2021). That’s 179% higher.

Gas prices have increased in 23 of the 24 EU Member States for which data are available, with the biggest jumps after the UK being seen in Estonia (+154%), Lithuania (+110%), and Bulgaria (+108%). This begs the question ‘how can energy-intensive industries survive in this climate?’ With large-scale industrial processes driven largely by compressors and vacuum pumps to operate machines and transport assets, that’s a critical question.
Condition monitoring
The answer is of course to look at the outgoings and real, tangible ways to cut expenditure on the factory floor. One way that is rapidly picking up traction among manufacturers across the breadth of the EU is acoustic imaging.
No piece of equipment is immune to the issue of machine failures and wear, however high-tech they are. Machines that aren’t operating optimally are costing users money in very real terms. This is where acoustic imaging comes in; on the frontline of condition monitoring, it promises to yield savings by picking up air leaks in real-time.
Savings costs
While isolated incidents may seem minimal, the costs of wasted energy can quickly snowball from a minor inconvenience to an acute concern.

Consider that with the average compressor system, approximately 80% of energy is lost through heat dissipation, meaning only 20% makes the transition into a usable output on the factory floor. From this, up to a third of this usable energy is lost to leaks. The energy that the users are paying more and more to use.
Why are air leaks so expensive?
Let’s put a measurable scale on a problem that can vary substantially by application. To do this, operators must first explore exactly how much a leak can impact production costs.
Take, for example, a compressed air leak from a small hole of just 1.5 millimetres on a network of compressed air at seven bars of pressure. Two years ago, with a price of €0.07 per kilowatt hour, that alone would have cost a company roughly €1500 (£1300) if users assume an operating time of 6000 hours per year.
Uncertain energy situation
The energy situation is worsening which could be a cost of up to £7500 a year for failing to identify a single small hole
Of course, the energy situation is worsening, which means that costs may be three, four, or even five times higher in some cases which could be a cost of up to £7500 a year for failing to identify a single small hole in a vital production component.
When users consider the scale of industrial manufacturing and the scope for leaks to crop up unnoticed, it is staggering that such a comparatively small hole can compound into such a large problem.
Driving down energy bills with the FLIR Si124 range
Newer acoustic imaging camera models such as the FLIR Si124 use several high-spec audible and ultrasound microphones to detect air leaks as they appear and boast an optimal bandwidth range of 2 - 65 kHz.
This range yields unmatched detection accuracy and identification down to even the smallest breach.
Detect discharge
The technology also gives handlers the ability to identify, photograph, or video the location of an air leak up to ten times faster meaning minimal downtime for the facility and prompt repair or replacement of the defective component.
In addition to this, it also detects partial discharge, floating discharge, and corona helping to curb potentially life-threatening events, as well as general maintenance issues.
Quicker identification of problem
Sound is superimposed by functional AIs to render a visual depiction of where the leak is
Operators benefit from the much quicker identification of problem parts and even can see the detected leak(s) as they appear.
This is because the sound is superimposed by functional AIs to render a visual depiction of where the leak is as well as gauge its severity, including recommended actions to resolve it.
Projective algorithms with FLIR Si124
In the case of the FLIR Si124, projective algorithms even estimate how much the leak will cost by evaluating the air lost in real-time, calculating the spend per kWh, and displaying an expected saving per year (or on a specified timeframe) ensuring that inspectors have clear evidence needed to solve problems and justify any incurred repair costs across the production line.
If users are a manufacturer struggling with the rising cost of energy, explore the new si124 range now to radically improve inspections in their facility.
