Compressed air leak survey revealed significant savings potential
Compressed air leaks are often invisible, yet their impact on a factory’s energy efficiency and costs can be substantial. At our customer’s production site, they wanted to gain a more detailed understanding of its compressed air system and invited Quant’s experts to conduct a survey to identify potential leaks.
“The customer asked if we could perform a compressed air leak survey, and we were happy to help. They are a long-term partner of ours, with whom we provide total maintenance services and continuously develop operations,” says Kristoffer Granström, Site Manager, Service Center, Quant.
Accurate and reliable inspection with ultrasound camera
The survey was carried out at the production facility in cooperation with Quant’s team. An ultrasound camera was used to detect compressed air leaks quickly and accurately, even those invisible to the naked eye.
“I first trained the local Quant personnel, and a few days later they performed the measurements on site. The results were then analyzed together with the site team, and finally we prepared a clear report for the customer, showing each leak location, its estimated size, and its impact on energy consumption,” Granström explains.
The visual and detailed report helps the customer prioritize repairs and monitor their effect on costs and energy efficiency.
More leaks than expected and even greater potential
The survey revealed several significant leaks, some large and some smaller. Although final savings calculations are still being completed, preliminary results already showed that repairing the leaks could deliver major savings in both energy consumption and compressor load.
“The number of leaks surprised the customer. The compressed air system was functioning normally, but the measurements revealed how much energy had previously been wasted,” Granström says.
Regular inspections ensure efficiency and safety
Quant recommends conducting a compressed air leak survey at least once a year, especially when production runs multiple shifts or when system modifications have been made.
“Regular inspections help keep the system in optimal condition and reduce risks. If leaks go undetected, the result can be not only higher energy costs but also increased equipment wear and potential safety hazards,” Granström reminds.
Tangible benefits for the customer
- Energy efficiency: Less waste and lower energy consumption
- Cost efficiency: Savings in compressor operation and maintenance costs
- Reliability and safety: Preventive maintenance reduces disturbances and downtime
- Sustainability: Smaller carbon footprint and more efficient use of resources
Towards more efficient and responsible production
This case example shows how preventive maintenance can uncover hidden savings potential while improving system safety at the same time.
“Even small actions can prevent major problems. When leaks are identified and repaired in time, production runs reliably and efficiently without wasted energy,” Granström concludes.
