Saving Water with Cooling Towers

ASHRAE Journal, Aug 2015, by Frank Morrison.

"Saving water with cooling towers. At first glance, this statement seems counterintuitive. Cooling towers save energy but aren’t they major users of water? This article will help readers understand the critical role evaporative heat transfer systems play in a sustainable environment, explore how water is consumed in such systems, and review the strategies that help minimize the use of both water and energy."

Troubleshoot Hot Hydraulics

Maintenance Technology, July 2015, by Jane Alexander.

"High oil temperatures in industrial hydraulic systems can lead to a world of hurt. Don’t let them get you down."

Manufacturing Energy Efficiency

ASHRAE Journal, July 2015, by Charles E. Gulledge III, and others.

2015 ASHRAE Technology Award Case Studies: Caterpillar Tractor Assembly Plant, Athens, GA.

"Realizing energy use reductions at Caterpillar’s heavy manufacturing complex required optimization of multiple component and system solutions. Iterative analysis was used to determine project-responsive configurations."

10 Cooling Tower Maintenance Tips

Air Conditioning, Heating, Refrigeration News, June 22, 2015, by Baltimore Aircoil Co.

"A well-maintained unit will continue to function at the original optimum efficiency. Over time, a neglected cooling tower’s leaving water temperature will increase, raising energy costs by up to 6 percent for every 2°F increase. However, a well-maintained cooling tower will continue to function at the original optimum efficiency, keeping energy costs low. These simple preventive cooling tower maintenance tips can help users save up to 15 percent on electricity costs. Routine maintenance also helps to conserve water and extend the operating life of cooling equipment."

ACEEE Presents Four 2015 Champion of Energy Efficiency in Industry Awards

American Council for an Energy-Efficient Economy (ACEEE), Aug. 6, 2015, Patrick Kiker.

"The American Council for an Energy-Efficient Economy (ACEEE) presented four Champion of Energy Efficiency Awards last night at its Summer Study on Energy Efficiency in Industry. The awards recognize leadership and accomplishment in the industrial energy efficiency field. Winners are selected based on demonstrated excellence in industrial leadership, lifetime achievement, research and development, implementation and deployment, or energy policy."

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

Pumps & Systems, July 2015, by Mark Berube.

"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)

Pumps & Systems, July 2015, by Ray Hardee.

"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."

Barriers to Industrial Energy Efficiency: Report to Congress

U.S. Department of Energy, June 2015.

"The industrial sector has shown steady progress in improving energy efficiency over the past few decades, and energy efficiency improvements are expected to continue..... There are barriers, however, that impede the adoption of energy efficient technologies and practices in the industrial sector. This report examines these barriers and identifies successful examples and opportunities to overcome these barriers."
