High-Altitude Mining and Steel Production in Peru

By Troy Dreier, Senior Editor, Compressed Air Best Practices® Magazine

Before CAGI data sheets were created, air compressor distributors and their customers could only go by the manufacturers’ claims. He found there wasn’t any uniformity to the numbers manufacturers put out, so making comparisons was challenging. Some compressed air manufacturers measured capacity from the bare airend, while others measured from the air compressor’s outlet.

Compressed Air Efficiency Opportunities in the Plastics Industry

By Dean E. Smith, iZ Systems for the Compressed Air Challenge®

As in most industrial categories, compressed air is critical to the operations of a plastics plant whether it is blow molding, injection molding, or other processes. The opportunities to improve supply side (compressor room) efficiency are similar to all industrial compressed air systems, but are even more prevalent in some plastics facilities, especially blow molding.

Saving Energy in Automotive Assembly

By Jim Timmersman

This automotive assembly facility has tremendous peaks and valleys in compressed air demand. Our audit using flow meters and pressure transducers with calibrated gauges has proven this. Our Phase 1 audit recommends the use of storage tanks and flow meters to reduce air consumption while stabilizing pressure.

Advanced Air Leak Detection Services

By Ed Attanasio

“Instead of adding supply equipment, we fix air leaks and incorporate high-efficiency air nozzles, blower packages and point-of-use receivers.” These demand-side actions stabilize compressed air system pressure and this ultimately increases production output, reduces production down-time and spoilage costs, and decreases the power costs of the compressed air system.

The “Dirty Thirty” – Discovering Pressure Differential at the Far End

By Ron Marshall for the Compressed Air Challenge®

Much attention and expense is often directed towards optimizing compressor control, clean-up equipment, system pressure / flow control and main system piping in an attempt to maintain adequate and stable pressure at the end use. Often forgotten are the components of the distribution system between the main system header and the end use.

Compressed Air Piping Distribution Systems

By Gary Wamsley, PE, CEM, JoGar Energy Services

Perhaps your facility recently had a compressed air system survey, conducted by an air systems services company, that resulted in a couple of major recommendations, such as:  • Install a new smaller compressor and new control systems on all of the units • Repair the many air leaks (identified as 30% of your system capacity)

Distribution Piping: Understanding Pressure Drop

By the Compressed Air Challenge®

The Compressed Air Challenge® (CAC) is a voluntary collaboration of industrial users; manufacturers, distributors and their associations; consultants; state research and development agencies; energy efficiency organizations; and utilities. This group has one purpose in mind - helping you enjoy the benefits of improved performance of your compressed air system. The mission of the Compressed Air Challenge (CAC) is to provide resources that educate industrial users about optimizing their compressed air systems.

Printing Facility Reduces Air Demand

Ron Marshall, CET, CIM, Manitoba Hydro

This article will focus on a compressed air system assessment done at a printing facility in Canada. The energy costs at the time, in Manitoba, were \$0.025 per kWh and the installation was of just 65 horsepower of air compressors.
