Air leakage diagnosis

It is commonly said that 15-30% of compressed air is lost due to leaks. To save energy in compressed air systems, it is essential not only to optimize the compressor but also to address air leaks. However, detecting air leaks by sound or sight alone is extremely difficult. At KOBELCO, we provide a diagnostic service that visualizes air leaks using frequency detection at pipes, joints, hoses, and connections. Our reports clearly present annual cost losses and CO2 emissions, making it easy to understand the impact of air leaks.

■Benefits of air leak diagnosis
・Reduces electricity costs and CO₂ emissions
・Enhances motivation and awareness of on-site workers
・When combined with a compressor-side energy-saving diagnosis, the "system air cost" (electricity cost required to produce 1m³/min) can be calculated, providing a more accurate understanding of loss costs and improvement effects
・Offers a one-stop solution for compressed air energy-saving across the entire system, including the compressor side

■Flow of air leak diagnosis
1.Identify leakage points using the Fluke ii905 diagnostic device
2.The device's ultrasonic sensor detects frequencies and determines the direction of the leak source
3.Generate a report on annual cost losses and CO₂ emissions based on the findings
