Leak detection

Compressed air leak detection and management

Unfortunately all compressed air systems will have compressed air leaks. Statistics suggest that the average leak rate is 25% with some plants losing as much as 80% of their compressed air through leaks. Following a regular programme of leak detection, repair and on-going management is one of the most cost effective measures you can take to see both immediate and long term energy cost savings.

Ultrasonic leak detection

Compressed air leak detection with Kaeser Compressors
The most comprehensive method of detecting compressed air leaks is with an Ultrasonic Leak Detector (USLD).

The most comprehensive method of detecting compressed air leaks is with an Ultrasonic Leak Detector (USLD). Fast and accurate, a USLD is the most versatile form of leak detection and can detect leaks as small as a pinhole! 

A USLD kit consists of directional microphones, amplifiers, and audio filters. As ultrasonic is a high frequency signal, the sound from a compressed air leak is both directional and localised to the source. This allows the detector to sense and therefore locate the source of leaks with relative ease. Once leaks have been detected they are tagged, recorded and fixed in order of priority. Ultrasonic leak detection can be performed while the plant is running as background noise will not interfere with the results. This means no downtime.

Continual improvement programme

Compressed air leak detection and repair will never be a one off requirement. As a compressed air system ages or changes with time it may need further attention. For long term results compressed air leak detection and repair needs to be part of an on-going programme.

How much are compressed air leaks costing you?

As an example, a compressor which operates at 6 bar will consume an additional 0.39 kW/h for one 1mm hole. This equates to an annual cost of $512, assuming the system has a power cost of 15 cents/kW/hr*.
