Compressed air provides a safe and reliable source of energy for a wide range of industrial processes. However, with more than 80% of the input energy being lost as heat, air compressors are inherently inefficient. Energy-efficient process design should opt for alternatives wherever possible, and limit compressed air usage to only processes that require it.
Existing compressed air systems can be effectively optimized by taking a systematic approach that reduces demand side air usage and utilizes appropriate technology and controls on the supply side. A properly managed compressed air system can not only save energy, but also reduce maintenance needs, improve production uptime, and lead to more reliable product quality.
Top Five Energy Performance Measures for Compressed Air Systems
- Eliminate inappropriate uses of compressed air
- Lower system pressure
- Improve system storage and controls
- Reduce leaks
- Upgrade equipment and maintenance
