Is a VFD a Cost-Effective Option for Your Application?

Pumps & Systems, July 2015, by Mark Berube.
http://www.pumpsandsystems.com/motors/july-2015-vfd-cost-effective-option-your-application

"While variable frequency drive (VFD) technology can significantly increase system efficiency by controlling pump speed, not every application requires a VFD. To determine when to apply this technology, end users must conduct detailed calculations to verify the cost-effectiveness of using a VFD."

10 Key Facts About Reciprocating Pumps

Pumps & Systems, July 2015, by Gary Dyson and Herb Tackett Jr.

"While centrifugal pumps are the subject of much training, the dwindling population of reciprocating pumps has led to a loss of understanding of this pump type's unique system design requirements. Centrifugal pump specifications are now commonly and incorrectly applied to reciprocating pumps, which can lead to significant reliability problems. End users should consider these 10 key facts about reciprocating pumps that can influence reliability and operation."

Understanding Piping System Controls (Part 1 of 2)

"Users have several options for controlling piping systems. Previous columns established that every piping system is composed of pump elements, process elements and control elements. This column will focus on the control elements, which improve the quality of the product. Control elements can be either passive or active."

Evaluating UPS System Efficiency

Pure Power (supplement to Consulting-Specifying Engineer), Summer 2015, by Kenneth Kutsmeda.

"Many modern uninterruptible power supply (UPS) systems have an energy-saving operating mode. Data show that very few data centers put it to use because of the potential risks."

Predicting the Future of RTUs [Rooftop Units]

Air Conditioning, Heating & Refrigeration News, June 15, 2015, by Jen Anesi.
http://www.achrnews.com/articles/129853-predicting-the-future-of-rtus

"With the U.S. Department of Energy (DOE) and industry stakeholders currently working together on a negotiated rulemaking setting new energy conservation standards for commercial package equipment, and with codes and standards mandating increased ventilation and higher efficiencies for this equipment, manufacturers are finding innovative ways to meet and exceed expectations while creating comfortable, healthy indoor environments for building occupants."

Plant Engineering: Lubrication Guides

Plant Engineering, June 2015.
http://www.plantengineering.com/advertise/lubrication-guide.html

"Friction is the enemy of efficiency. A sound lubrication strategy is essential to keep all the gears in your operation running at their best. The emergence of synthetic lubricants has helped improve the performance of machinery and has become an important part of any maintenance manager’s arsenal in the fight against friction.

The Guide will provide you with a comprehensive look at the available lubricants. This year's guide also considers the important issues of environmental impact of oils, greases and fluids, the need for a strong culture of lubrication excellence, and an in-depth look at some of the new standards in bearings and seals." 

VFD Trends and Solutions for Drive Systems

Plant Engineering, June 2015, by Alex Ward.
http://www.plantengineering.com/single-article/vfd-trends-and-solutions-for-drive-systems/c655baa26fc5bd8e9e7a4e700ce2b7c5.html

"The increase in variable frequency drive (VFD) installations across the globe has meant that drives are being applied in more challenging system environments. Not only is the environment challenging, but drives also have a few inherited issues that can limit the overall system performance. Harmonics mitigation, filtering voltage spikes are two key issues."

Maximizing Dust Collection System Efficiency

Compressed Air Best Practices, June 2015, by Hank van Ormer.
http://www.airbestpractices.com/system-assessments/air-treatmentn2/maximizing-dust-collection-system-efficiency

"A commonly overlooked area of inefficient compressed air use is dust collector pulse-jet cleaning — either bag (sock) type, or reverse flow filter type. Dust collector systems are vital to many plant operations, particularly with respect to meeting both indoor and outdoor air quality standards. They are also often used to collect income-producing product. At the heart of a pulse-jet type dust collector is the proper installation and availability of compressed air."

Determining the Economic Value of Compressed Air Measurement Systems

Compressed Air Best Practices, June 2015, by Tim Dugan.
http://www.airbestpractices.com/technology/instrumentation/determining-economic-value-compressed-air-measurement-systems

"A common adage that has been quoted many times in this journal is: “If you don’t measure it, you can’t manage it.” This is partly true. It assumes that managers are willing and able to manage the costs and reliability of their compressed air system. Without data, however, they can’t do an effective job. But because managers are at times already overwhelmed with data, more data doesn’t automatically make them a better manager. A better way of saying it is: 'Appropriate measurement can make you a better manager.'"

Barriers to Industrial Energy Efficiency: Report to Congress

U.S. Department of Energy, June 2015.
http://www.energy.gov/eere/amo/downloads/barriers-industrial-energy-efficiency-report-congress-june-2015

"This report examines barriers that impede the adoption of energy efficient technologies and practices in the industrial sector, and identifies successful examples and opportunities to overcome these barriers. Three groups of energy efficiency technologies and measures were examined: industrial end-use energy efficiency, industrial demand response, and industrial combined heat and power. This report also includes the estimated economic benefits from hypothetical Federal energy efficiency matching grants, as directed by the Act."
