Start with Monitoring to Achieve Compressed Air System Efficiencies

By Keith Harger, Parker Hannifin

Compressed air represents one of the largest opportunities for immediate energy savings, which accounts for an average of 15% of an industrial facility’s electrical consumption. In fact, over a 10-year period, electricity can make up 76% of the total compressed air system costs. Monitoring compressed air usage, identifying compressed air waste and inefficiencies, and making investments in new compressed air equipment – including piping – are tangible ways businesses can cut their operating costs by lowering their electricity bill.

Use Baseline Measurements to Improve Compressed Air Supply Performance

By Tom Taranto, Data Power Services, LLC.

Baseline measurements include flow, power, pressure, production output, and other relevant variables impacting compressed air use. These data evaluate trending averages to develop Key Performance Indicator (KPI) and Energy Performance Indicator (EnPI) parameters and establish base‑year performance. The focus of this article is the application, evaluation, and analysis of baseline measurements to provide information necessary to improve Compressed Air Supply Efficiency.

Fayetteville Wastewater Treatment Plant Lowers Operational Costs, Increases Efficiencies

By Mike Grennier, Compressed Air Best Practices® Magazine

The plant upgrades, in combination with a progressive management strategy, allows the plant to consume less energy and reduce its reliance on outside contractors for biosolids removal, resulting in total operational savings of approximately $60,000 per year. The plant is also positioned to efficiently manage the area’s wastewater for decades to come.

Don’t Overlook Tubing Volume with Manifold-Mounted Pneumatic Valves To Conserve Energy

By John Martin, SMC Corporation of America

The advent of manifold-mounted, plug-in pneumatic valves has been a boon for machine builders. It allows them to mount complete valve packages in a safe and secure location on a machine. Using a D-sub connector, serial interface module, or similar single-point wiring system, all of the electrical control outputs can feed into one location on the manifold, greatly simplifying the wiring.

The Hydraulic Air Compressor: An Old Idea Made New

By Ron Marshall, Marshall Compressed Air Consulting

The team is building on engineering concepts that were used to develop the first hydraulic air compressor at Dominion Cotton Mills, Magog, Quebec, Canada, over 100 years ago. The basic principles of the HAC were then used to produce compressed air at 17 locations worldwide, including the last at Ragged Chutes near Cobalt, Ontario, Canada, over 100 years ago. This article discusses the development the HAC in this decade and the continuing work at Laurentian University, Ontario, to modernize the concept.
