The other day I performed a Google search for ‘How to detect an air leak’. Not surprisingly it came up with millions of results, over 18 million in fact.
Whether solving the problem in a commercial establishment or a domestic home environment, the majority of search results pointed to one solution. Namely, soapy water!
Before we all ridicule the idea as belonging to a bygone era, take a vehicle with a slow puncture to a tyre fitting depot and the chances are they remove the wheel and spin it in water to determine the leak. It’s a simple time proven method for determining leaks from pressurized systems.
But of course, not all equipment can be placed in soapy water. What if a system is known to be losing pressure and yet the lines carrying the compressed air from the source are located 10 metres above the ground, and dismantling the system is out of the question? Thankfully there is a fast and effective solution to hand.
Each time air or indeed any gas, leaks from a pressured system there is an associated sound. If the leak is significant, it can be audible to the human ear and therefore easily identified and rectified accordingly. However, most leaks in high pressure systems are extremely small and are out of the range of a human ear.
Think about a pressured air system on a large factory delivering compressed air from a bank of compressors to various stages of production throughout the manufacturing process. The chances are there are hundreds if not thousands of connections in the form of joints, reducers, valves, elbows, condensers etc. Each of these has the potential to leak small amounts of air, reducing the pressure of the system.
One leak might make very little difference but multiply this by the number of potential leaking joints and efficiency can be significantly compromised. The compressor will seek to compensate for any pressure loss by simply working harder. However, as any engineer will know, compressors can be expensive to operate in terms of energy and therefore will certainly increase an operators energy consumption.
With electricity costs being so much higher in Europe due to geopolitical factors in recent years, most companies are seeking to reduce the amount of energy used. Having a compressor work overtime to compensate for leaking joints is certainly not something senior management would smile about!
These scenarios are certainly not uncommon, in fact one European compressor manufacturer has stated that in some industrial settings, up to 80% of air generated is lot in leaks. So clearly identifying these small leaks can make a real difference to a company’s energy bills.
Although the sound produced by a small leak is inaudible to the human ear a high performance acoustic imaging camera such as the FLIR Teledyne Si2 – LD will have absolutely no problem identifying the source. Launched earlier this year the camera is capable of detecting leaks of 0.05 litres per minute at a distance of 10 metres, meaning those elevated air lines pose no problem for this latest instrument in the FLIR acoustic imaging camera line up.
For closer work the camera is even more sensitive and can detects minute leaks of 0.0032 litres per minute at a distance of 2.5 metres. Coupled with this improvement, the third-generation camera has improved microphones now capable of detecting sounds over an extremely wide frequency range, namely 2 – 130 kHz.
Areas of plant are often dark or dimly lit. for this reason FLIR have fitted the FLIR Si2-series of cameras with two powerful LED lights to make component identification easy even in poorly lit conditions.
Of course, it’s not just compressed air that the camera is capable of detecting; noise emitted by any escaping gas is identified by the powerful microphones. However that’s only part of the story.
The FLIR Si2-LD has built in software termed Industrial Gas Quantification. If the leaking gas is ammonia, hydrogen, helium, or carbon dioxide, very commonly used gases in a number of industries, the software is capable of quantifying the financial loss caused by the leak. By simply entering factors such as the cost per litre, the software identifies the amount each leak is causing over a given period of time. Such data is invaluable to financial analysts and senior management within an organisation.
It goes without saying that the financial considerations are only one aspect of leaking gas. The gases mentioned above all carry significant health hazards and can present a variety of dangers to personnel if allowed to leak for any period of time. Ammonia and carbon dioxide can cause serious breathing problems and asphyxiation even in smaller concentrations, whereas hydrogen can explode in the presence of oxygen. Clearly the cost of such problems goes way beyond any financial considerations.
We’ve come a long way since the ‘soap and water’ approach. See how the latest technology from FLIR Teledyne can help in reducing downtime, lower energy bills and improve safety in your organisation.

The AHR Expo (International Air-Conditioning, Heating, Refrigerating Exposition) is now accepting submissions for the 2023 Innovation Awards. Exhibitors are encouraged to enter recent or upgraded products for the competition. Entries are welcomed through August 9, 2022. The 2023 AHR Expo will return to Atlanta at the Georgia World Congress Center February 6-8, 2023. To request more information about the Innovation Awards, or to receive forms for entry, please email Kim Pires at kpires@iecshows.com.
“If Vegas is any indicator of what’s ahead for HVACR then Atlanta will certainly be an impressive showing,” said show manager Mark Stevens. “Our ten category winners and 2022 Product of the Year winner, Danfoss, blew us away with innovative solutions that demonstrate just how revolutionary the technology within this industry is becoming. It’s really a remarkable gauge of just how fast this industry is moving,” continued Stevens.
The Innovation Awards aim to honor the most inventive, useful and original products, systems and technologies in the marketplace. Exhibitors are encouraged to submit products and technologies to showcase solutions for new and existing challenges and new avenues for industry growth.
Once submitted, all entries are evaluated by a panel of third-party ASHRAE members with over 20 years of professional engineering experience. The panel uses a review process to tally points based on application, innovation, value and market impact. Winners are then selected in ten industry categories, including building automation; cooling; heating; indoor air quality; plumbing; refrigeration; software; sustainable solutions; tools and instruments; and ventilation. An overall Product of the Year will be selected from the pool of category winners and will be announced at the show in Atlanta.
The Innovation Awards as an investment in our workforce
In 2022 AHR Expo introduced a workforce development program in which entry fees from the Innovation Awards program were used to support a local dual-HVAC high school. With the success of the awards in Vegas, AHR Expo was able to donate $25,000 directly to the program as well as host 25 students for a field trip on the show floor. In 2023, AHR Expo aims to work with the Atlanta Public School district to award donation funds to a similar program, with the hopes of growing into other areas of service within HVAC including computer programming and engineering.
“This industry is special,” said Stevens. “If you’ve been to the AHR Expo you understand the feeling of community and connectedness−even more now than ever coming out of the challenging years behind us.
“We are poised to build a fantastic future with HVACR leading the transformation of our built environment. The Innovation Awards lend a preview of this and it is encouraging to see how we are moving forward as an industry. Manufacturers continue to exceed expectations by showing up, making improvements and pushing forward; and while we award only ten companies, we see hundreds in our submissions. We can’t wait to see what’s to come in Atlanta,” concluded Stevens.

A part of Emerson’s professional tools portfolio, RIDGID employs 16 fathers and their children
RIDGID®, a part of Emerson’s professional tools portfolio, celebrated Father’s Day by creating a tribute video recognizing how the work fathers do can inspire their children’s career choices. The inspiration behind the video came from RIDGID’s own workforce: currently sixteen RIDGID employees are considered “legacies” – meaning they have dads that worked for the company’s manufacturing team before them. These “RIDGID Dads” and now their children build RIDGID tools in Elyria, OH, that are used by skilled trade professionals across the country, many by family-owned companies that also include fathers and their children.
“When we ask trade professionals how they got into the industry, learning from their fathers is a common response,” said Becky Brotherton, director of engagement marketing, RIDGID for Emerson. “Passing along their skills to the next generation is a legacy that lasts, not only in their children, but also in the infrastructure built and maintained through their challenging careers. Father’s Day seemed like the ideal time to celebrate the legacy that we see regularly on jobsites and in our manufacturing team.”
The video, shared last week on RIDGID social channels and viewed more than 2,000 times, features Russell and Josh Halstead, co-owners of Valu-Rooter® in Elyria, OH, and Jose and Bryan Gonzalez, RIDGID employees.
“I remember him having this determination and hard work to get the job done, but to do it right the first time,” said Josh Halstead, of his dad. “I started working in high school to make some money, but coming out of school I became more interested in this line of work. I wanted to be the best that I could be. I’ve always had the goal of being the best plumber. I want people to hear our name and think of quality.”
“The number of generations, including fathers and their children, working at our company is a unique aspect of our team,” said Danielle Hart, director of human resources, RIDGID for Emerson. “It’s a distinction that we’re proud of and one that we think contributes to a positive work environment.”
View the video on RIDGID social channels, including Instagram – @ridgidtools – and Facebook – @RIDGIDTools.
RIDGID has released Father’s Day videos the last several years, each a tribute to dads in the trades and the influence they have on their children. Previous videos can also be viewed on their YouTube channel.
