This paper discusses an energy efficient compressed air system at an industrial automation components manufacturing facility. The authors performed and energy assessment as part of the DOE’s Industrial Assessment Center program and followed up with additional investigations on the compressed air system. The compressed air system utilizes an outlet pressure transducer to a microcontroller to adj...

In recent years, energy engineers have examined industrial compressed air systems looking for opportunities to reduce the energy consumption, which in turn leads to operating cost savings. After identifying possible actions that might lead to a reduction in energy usage, it is necessary to perform an analysis to determine the projected energy and cost savings, and to estimate the cost of implem...

Detection of Low Frequency (around 40kHz) Ultrasound is a powerful method for maintenance inspection of plant and machinery. Many failure conditions give early indication by the production of ultrasound. These include pressure leaks, electrical discharge and deterioration of bearings and other machinery. Leakage of compressed air has become a particular issue recently with the promotion of ener...

The power draw characteristics of air compressors are primarily determined by the type of compressor control and the relationship between the compressor’s output capacity and the compressed air demand in the plant. In this paper, we review the most common types of compressor control for small reciprocating and rotary air compressors, and derive relations for estimating compressed air output as ...
