Optimizing Vacuum Generators in Case Packers and Palletizers
This was a complete supply and demand-side system assessment. The supply-side audit involved shutting off old air compressors and purchasing newer more efficient air compressors and dryers. The demand-side audit involved finding ways to improve the piping and reduce compressed air consumption.
Annual plant electric costs for compressed air production, as operating today, are \$3,050,625 per year. If the electric costs of \$27,811 associated with operating ancillary equipment such as dryers are included the total electric costs for operating the air system are \$3,078,436 per year.
