No-cost and low-cost actions
- Reduce header pressure to the minimum the process actually requires
- Fix tagged leaks and re-measure to confirm the recovery
- Isolate air supply to idle sections and shifts
- Sequence compressors so machines run loaded rather than part-loaded
- Keep inlet air cool and filters clean — inlet condition changes specific power
- Restore inter-cooler and after-cooler performance on the cooling water side
- Replace air-driven applications where an electric alternative exists
