Improving the Efficiency of Pumping Systems through Pump System Optimization

By Matthew Derner, Manager, Business Development, Pump System Programs, The Hydraulic Institute

The U.S. Department of Energy’s 2002 Motor Market Assessment established that pumping systems offer the greatest optimization potential of all types of fluid systems, with potential savings up to 75% and an average net savings of 20.1%. In this article, The Hydraulic Institute defines the steps for a pump system optimization.

Pneumatic vs. Electric Tool Calculations and Considerations

By Jerry Zolkowski, PE, CEM, Senior Engineer, Consumers Energy Business Solutions

Figuring out the energy savings for the switch from pneumatic to electric tools requires an estimate of energy use for each case. The effect of replacing a few tools in a large compressed air system may be too small to detect using power monitoring on the air compressors. However, it is still a good practice, and when part of a larger program to reduce air consumption, the combined efforts will amount to something measurable. Another positive aspect may be that reduced compressed air use frees up needed air compressor capacity.

Pneumatic Control in Modular Wastewater Treatment Plants

By Compressed Air Best Practices® Magazine

The design of wastewater treatment plants is changing, and it has something to do with LEGO® bricks. More specifically, it has to do with how large and complex LEGO structures are built. If you follow the instructions carefully, you build module after module, eventually piecing them together to create a fully functional and cohesive unit.

Remote Diagnostics for Water Filtration Systems

By Craig Correia, Process Automation Industry Manager, Festo Corporation

Productivity is more reliable when equipment can be monitored to detect incipient failures and take corrective action before the plant goes down. But many devices, such as analog control valves, pneumatic valve terminals and field sensors, often do not offer diagnostic feedback, or it is not being used. This white paper describes how this problem is being addressed, and includes an example of pneumatic valve terminals that can monitor, among other things, open load or coil currents at the specific valve and pressure inside the valve terminal.

Choosing Durable “No-Air-Leak” Pneumatic Tubing Fittings

By Don van Ormer, Air Power USA

Over many years of reviewing industrial compressed air production machinery, of many types and styles, there is one common thread or complaint; “push-to-connect pneumatic tubing connections/fittings are a continual source of compressed air leaks and production interruptions.”  Probably seventy-five to eighty percent of push-to-connect type tubing fittings use flexible tubing selected for lower material cost and assembly rather than an alternate appropriate hard metallic tubing.

Machine Builders Optimize Pneumatic Circuit Tubing Volumes

By Jon Jensen, John Martin and Chris Latham, SMC USA

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. Plumbing issues are reduced, since a single air pressure line can be used to feed a common pressure gallery. The same advantage applies to the common exhaust gallery. No longer would both a plumber and an electrician be required to replace a valve, since any valve can be replaced without disturbing electrical connections or plumbing lines.

Advanced Automation Lowers Labor Cost and Improves Performance at the Las Palmas, California, Waste Water Treatment Plant

By Nate Ventress, Process Automation Specialist, Western Region, Festo

Recently the capacity of the Las Palmas, California, waste water treatment operations were expanded by combining two plants and making one centralized filtration center. The new center expanded the flow capacity from 162,000 Gallons per Day (GPD) combined to 288,000 GPD when the manually controlled reclaimed water operations were updated to a state-of-the-art automated system. Reclaimed water from the plant irrigates local community green spaces. The new automated system ensures lower labor costs, consistent quality, and peak efficiency in the process of reclaiming waste water for irrigation.

Pneumatic Circuit Analysis for Energy Efficiency

By Clint Hodge, ASCO Numatics, EMERSON Industrial Automation

Currently, and for good reason, much attention is being focused on the conservation of energy. Compressed air, like electricity and gas, is an energy resource. It has often been referred to as the third utility. As with all energy sources, our global environment demands that it be conserved and used wisely.

Improved Aeration Efficiency through Design and Control

By Matthew Gray, Senior Process Engineer and Steve Kestel, Lead Systems Engineer, BioChem Technology, Inc.

With the recent and future increases of the cost of energy, operating a wastewater treatment plant (WWTP) as efficiently as possible has become one of the most important factors that operators and managers are facing today. The implementation of a properly designed aeration control system has been reported by the United Sates Environmental Protection Agency to reduce aeration energy by 25 to 40 percent.

How Efficient Are Those Pneumatic Valves?

By Richard F. Bullers, SMC Corporation of America

Back when gasoline was 35 cents a gallon, the term “environmental technology” was not well known. Engineers did not often promote the benefits of building low-energy consumption pneumatic valves among their peers. Recycling or conservation of resources was seldom discussed with any seriousness. In reality, the conversation was more likely to have turned to the muscle cars of the day and how much horsepower they would generate.

Plastic Molder Reduces $3.2 Million Energy Spend with Pneumatic Cylinder Retrofits

By Gary Wamsely, JoGar Energy Services

A plastics molding plant had engaged us to conduct an ‘on-site’ Energy Assessment of their facility. The annual ‘spend’ for electricity, natural gas, and water was about \$3.2 million for this modern 275,000 square foot, fully air-conditioned facility. During the Review, several opportunities were identified and delineated in lighting, HVAC, process ventilation, the water systems and energy supply contracts. However, the most significant savings were in their compressed air system.
