Becoming a more efficient businees
Compressed air is often considered an on-site generated energy source since energy is needed to convert electricity into compressed air. It can be one of the most expensive sources of energy in a plant.
Very often, the actual cost of generation is unknown. Only 10% to 20% of the energy required to generate compressed air ever reaches the point of use, while the remaining energy is wasted in the form of heat.
The over-all efficiency of a typical compressed air system can be as low as 10%-15%. A study by the U.S. Department of Energy suggests that more than 50% of industrial compressed air systems could see significant energy savings through low-cost improvements.
The following information includes tips to help ensure that compressors are running as efficiently as possible:
• Reduce the pressure, test for and fix leaks
• More efficient delivery of compressed air
• Switch off compressors when not in use and measure air use
• Use variable speed drive technology and heat recovery option
