Industries today face growing pressure to improve efficiency and earn profit amidst rising energy prices and operational expenses. Compressed air leaks in pressurized systems are among some of the highest cost drivers, leading to substantial financial losses due to energy waste. Detecting compressed air leaks and resolving them is essential for improving profitability.
In this blog, we will examine the financial impact of compressed air leaks and how acoustic imaging technology uncovers invisible losses, enhances industrial efficiency, and accelerates ROI.
How much do compressed air leaks cost?
Compressed air leaks are essential for driving pneumatic tools, production lines, and safety systems, accounting for approximately 10% of Europe’s industrial energy consumption. However, undetected leaks are a hidden drain on industrial resources, resulting in:
- Energy losses: Compressed air leaks account for an estimated 20–30% of energy waste in industrial systems, driving up costs and reducing system efficiency.
- Operational inefficiencies: Leaks often prevent systems from running at full capacity, with up to a third of compressors compensating for losses in others. This results in increased maintenance costs, unplanned downtime, and reduced productivity.
For example, energy costs from compressed air leaks in a petrochemical plant can be significant. Just a 6-millimeter (1/4-inch) leak can cost around €12,812 annually ($13,500).
Now imagine if the plant experiences multiple leaks, let’s say 10 leaks of this size, the total annual cost of leaks would be:
10 leaks × €12,812 ($13,500) = €128,120 ($135,000) annually in energy losses.
Limitations of traditional compressed air leak inspection
Compressed air leak inspection is a challenge, often relying on outdated methods such as listening for hissing sounds or applying soapy water to exposed joints. These techniques may work for detecting some leaks, but they fail to uncover those that occur at ultrasonic frequencies, which are inaudible to the human ear. This can create a false sense of confidence in the airtightness of the system. Leaks in hard-to-reach areas or those too small to detect with traditional methods are frequently overlooked, even in systems that are regularly checked.
- Inaccuracy: Small leaks in noisy environments are often missed, leading to overlooked problems that escalate over time.
- Manual effort: Inspections require significant time and labor and can result in human error.
- Operational disruptions: Traditional methods often require downtime, delaying production and increasing costs.
Given the complexity and scale of today’s industrial operations, these methods no longer suffice. Industries need a smarter, more reliable solution to inspect compressed air leaks proactively.
The solution: Acoustic imaging technology
Acoustic imaging technology, such as the handheld Sorama CAM iV64s or fixed acoustic monitor Sorama L642, represents a breakthrough in compressed air leak detection. These acoustic cameras visualize the sound waves (both audible and ultrasonic) emitted by escaping air, providing actionable insights in real time.
How an acoustic camera works:
When a pressurized system leaks, the leak creates sound waves, due to turbulence and rapid pressure changes in the air. The acoustic camera uses an array of 64 microphones to capture these ultrasonic air leaks and pinpoint their exact location. The results are displayed as a heatmap overlaid on a real time video from the integrated HD-camera, enabling maintenance teams to detect leaks with precision.
Advantages of acoustic imaging technology
• Accurate detection: High-resolution imaging localizes even the smallest leaks in noisy environments.
• Efficiency: Real-time visualization allows for immediate action, minimizes downtime and accelerates repairs.
• Flexibility: Sorama CAM iV64s is ideal for field inspections while Sorama L642 can be used for continuous monitoring or integrated with robotics for autonomous inspection.
• Scalability: Detect leaks in systems ranging from small installations to complex infrastructures using handheld device or combine multiple fixed monitors to cover large areas for 24/7 monitoring.
Real-life applications and benefits
Industries such as petrochemical, food and beverage, and manufacturing rely on pressurized systems and can benefit greatly from acoustic imaging for compressed air leak detection.
- Proactive inspection: By detecting compressed air leaks early, businesses can prevent costly energy losses and ensure uninterrupted operations.
- Maximized efficiency: Optimized maintenance schedules reduce unplanned downtime, extend equipment lifespan, and conserve valuable energy resources.
- Enhanced ROI: Reducing energy waste, downtime, and ensuring longevity of machinery result in accelerated ROI.
Return on investment
Investing in an acoustic camera for industrial leak detection offers measurable financial returns. Consider the earlier example of a petrochemical plant with 10 small leaks costing around €130,000 ($136,552) annually.
Addressing leaks early can lead to 30% to 50% savings on these costs.
- With 30% savings:
€128,120 ($135,000) × 30% = €38,436 ($40,500) savings per year
- With 50% savings:
€128,120 ($135,000) × 50% = €64,060 ($67,500) savings per year
With an average purchase price of €10,000 ($10,504) the ROI for an ultrasonic compressed air leak detector like the Sorama CAM iV64s is realized within 2 months. These savings free up resources for operational improvements, increase efficiency, and strengthen profitability.
