The production of compressed air represents roughly one-third of the total energy expenses in an industrial setting. The Compressed Air Challenge indicates that approximately 30% of this compressed air is lost due to leaks. Consequently, nearly 10% of the energy costs incurred by the facility are squandered because of inadequate connections, malfunctioning air valves, and improper installations. Beyond financial waste, these leaks can lead to various operational inefficiencies. A reduction in system pressure can hinder the performance of end users, negatively impacting production efficiency. Additionally, this pressure drop may result in more frequent cycling of equipment, which can diminish the lifespan of compressors and other machinery. If leaks compromise the supply volume, it may create a false impression that additional compressor capacity is required, thereby escalating operating expenses.
When a leak occurs, it generates ultrasonic noise due to turbulence, often at frequencies above 20 kHz, which are inaudible to the human ear. The EXAIR Ultrasonic Leak Detector, model 9207, is designed to detect these frequencies and convert them into audible sounds through a technique known as “heterodyning.” This device features a signal strength indicator and a bar graph display, enabling the identification of even the smallest leaks. It includes two attachments: a parabolic microphone for detecting leaks from distances of up to 20 feet, and a tube attachment for pinpointing the exact location of a leak among multiple connections within a pipe. Once a leak is identified, it can be marked for repair.
The ULD is equipped with attachments designed to minimize background noise commonly encountered in industrial settings, featuring “+” and “-” buttons for precise adjustments to the meter’s sensitivity. This latest model enhances leak detection capabilities in difficult-to-access locations and adheres to the IEC 61326-1 standard, ensuring its functionality in the typical electromagnetic environments present in industrial facilities.
In most industrial facilities, huge amounts of savings can be realized rather easily by implementing a leak protection program. If you have questions about introducing the Ultrasonic Leak Detector to your leak protection program, please do not hesitate to reach out.
