Case Study: Reduced Compressed Air Consumption Techniques

Three Compressed Air Demand-Reduction Projects at a Glass Plant

Compressed Air Best Practices, December 12, 2013

This glass container plant is very large and very well laid out with a very apparent “culture of quality.” They run (14) IS machines and inspection lines on four furnaces.

Currently the plant has three basic air systems: low-pressure air (52 psig); high pressure air (100 psig) and oil free instrument air (100 psig). The low-pressure air averages about 21,700 scfm with peaks to about 25,000 scfm. The high-pressure air system and the instrument air system average about 4,000 scfm at 100 psig with peaks to less than 4,800 scfm.
