Detect leaks in compressed air
March 1st 2006

Compressed air has many benefits in terms of safety, reliability and flexibility. However, it is relatively costly to produce and the leak rate on an unmanaged compressed air system is as high as 40%.

domnick hunter offers a range of testing services, including leak detection. When compressed air escapes from piping it generates a frequency of 38lhz, although the sound level varies according to pressure, temperature and humidity, the frequency remains consistent, which allows leaks to be detected ultrasonically without background noises distorting the measurement.

Service engineers use the latest ultrasonic equipment to detect leaks up to 50m away. The service includes a detailed report that estimates the consequential cost of the leak, recommends a solution and indicates the likely savings.

While the obvious saving that comes from correcting air leaks is reduced electricity bills, pressure drops affect the efficiency of downstream processes and can lead to product defects
