Leak Detection for Compressed Air and Gases
Making energy losses visible and turning them into savings
Studies show that up to 30 percent of the generated compressed air volume is lost through undetected leaks. The result is high energy costs, overloaded compressors, and inefficient compressed air production. Therefore, it is essential to identify, monitor, and repair leaks in compressed air systems. Modern leak detection methods allow precise localization of leaks, which can then be permanently fixed by qualified personnel.
SUTO iTEC offers ultrasonic leak detection instruments that are easy to use. This is complemented by the LMS Leak Management Software, which generates audit reports with one click and supports efficient energy management.
SUTO iTEC Leak Detectors and Software
SUTO iTEC offers modern solutions for the efficient detection and analysis of compressed air leaks. They enable fast localization, quantification and documentation to save energy and ensure system performance.
Why Early Leak Detection Matters
Leaks in compressed air and gas systems often develop gradually and remain unnoticed for long periods. During this time, energy consumption rises because compressors must run harder to maintain the required operating pressure. These hidden losses accumulate over months and can significantly increase operating costs. Early leak detection prevents this escalation by ensuring that leaks are identified and repaired before they impact system performance.
Modern ultrasonic technology and acoustic leak cameras with visual leak mapping make even the smallest leaks immediately detectable and provide clear guidance on their exact location. This allows for targeted repairs without unnecessary downtime. At the same time, operators gain a transparent overview of the system’s overall condition. Regular inspections improve efficiency, reduce energy consumption, and contribute to a stable and reliable compressed air or gas supply.
Costs and Savings Potential Illustrated with an Example
Many companies wonder: What does leak detection in their compressed air system cost, and is the effort worthwhile?
The answer is: Yes. Eliminating just a few medium-sized leaks can yield annual savings in energy costs ranging from four to five figures. Today, there are clear tools and tables available for calculating compressed air leaks, making it easy to determine the savings potential.
A concrete example
A leak with a diameter of just 2 mm causes a compressed air loss of approximately 13 l/s at a working pressure of 7 bar. This corresponds to annual additional costs of about 1,200 euros with 8,000 operating hours. The sooner you act, the greater the impact.
Where Can Leaks Occur in Compressed Air Systems?
Leaks are among the most common maintenance issues and can occur anywhere in the system. They require careful localization and subsequent repair.
Leaks frequently occur at the following points in the compressed air system:
-
Fittings, pipes, hoses, and couplings: Undetected Push-to-Lock connections and improperly installed hoses are among the most common causes of compressed air losses.
-
Open condensate traps: Improper operation, contaminated seals, and defective valves are frequent problem sources that can lead to inefficient operation.
-
Regulators, lubricators, and filters: Incorrect installation or inadequate maintenance can lead to leaks and thus a drop in pressure.
-
Connection separations: Missing or damaged O-rings can compromise the sealing of connections and lead to leaks.
-
Shut-off and control valves: Worn seals on the shaft can also lead to leaks, reducing system efficiency.
-
Point-of-use devices: Poorly maintained or outdated devices may exhibit internal leaks that increase compressed air consumption.
-
Thread sealants: Improperly applied or unsuitable thread sealants can cause leaks and jeopardize system integrity.
-
Flanges: Missing welds or inadequate seals are common issues that can lead to pressure losses.
A systematic leak check with professional leak detection devices helps to quickly identify and address these leaks, ideally as part of regular energy monitoring.
Ultrasonic Leak Detection – The Modern Method
Ultrasonic measurement is one of the most effective methods for locating compressed air leaks. This technique captures the high frequency sounds generated when compressed air escapes and converts them into audible signals. It allows precise identification of leaks, even in noisy environments, helping operators optimize compressed air consumption and reduce operating costs.
In addition to handheld ultrasonic devices, modern acoustic leak camera technology uses an array of ultrasonic microphones to visualize leaks directly on a live image. This makes it possible to scan large areas quickly and pinpoint leak locations with high accuracy, even in complex or hard to access installations.
The advantages of ultrasonic and acoustic leak camera detection
- Reliable detection of even the smallest leaks
-
Independent of ambient noise levels
-
Quick and easy application with minimal training
-
Testing possible during operation
- High detection accuracy through directional signal capture and visual mapping
Wireless headsets, visual displays, and advanced filtering functions ensure efficient and comfortable use, even in loud industrial environments.
