Savings At The Steel Mill Compressed Air Best Practices

The steel mill had previously used 100 psig compressed air for many low-pressure applications (air wipes, blow-offs, etc). It was determined that the plant could reduce their compressed air system energy consumption by as much as 596 KW by switching these process over to low-pressure blowers, without any sacrifice to process or quality.
