Preventive Maintenance for Profit

Plant Services, May 2014, by John Kravontka.
http://www.plantservices.com/articles/2014/preventive-maintenance-for-profit/?show=all

"The challenge facing manufacturers is how to implement a maintenance program that will provide immediate return. It can take as many as five or 10 years to train maintenance staff and introduce programs for them to carry out."

Determine Total Cost of Ownership When Selecting Medium-Voltage Drives (Part 2)

Pumps & Systems, Jun. 2014, by Mark W. Harshman.

"Part One of this two-part series (Pumps & Systems, May 2014) explained how factors other than initial purchase price work together to generate the total cost of ownership (TCO) for medium-voltage variable frequency drives (VFDs). Part Two discusses what creates high reliability in a medium-voltage VFD."

The Next Generation of U.S. Energy Efficiency Motor Regulations

Pumps & Systems, Jun. 2014, by John Malinowski.

"Several years ago, the U.S. Department of Energy (DOE) conducted a technical study about how to raise “small” motors’ efficiency levels. After years of study, the Small Motor Rule was passed, covering General Purpose two-digit NEMA frame (and IEC equivalents), single- and three-phase, 1/4- through 3-horsepower motors in open enclosures. Totally enclosed, fan-cooled (TEFC) motors are not included. This regulation will take effect on April 9, 2015."

Grounding Rings Rescue Paper Mill’s Bearings

Maintenance Technology, May 2014.

"At a paper mill in the Midwest, every new motor that is to be controlled by a variable frequency drive (VFD) must be tested. If shaft voltages are found, the motor must be equipped with an AEGIS® Bearing Protection Ring to divert damaging currents to ground. The plant’s electrical reliability engineer established this money-saving specification after many years of frustration from recurring bearing failures."

Eccentric Disc Pumps Create Product Recovery Cost Savings

Pumps & Systems, Jun. 2014, by Wallace Wittkoff.

"Targeted product recovery in hygienic manufacturing reduces waste, decreases operating costs and maximizes the use of raw materials and end products."

Industrial Drive Provides Savings for Swedish Paper Mill

Pumps & Systems, Jun. 2014, by Ken Graber.

"The pumping operation experienced an 80-percent reduction in energy use."

Same Treatment Quality, Less Energy [Wastewater]

Treatment Plant Operator, Jun. 2014, by Doug Day.

"A Mississippi plant copes with high flows from two poultry plants with a new SCADA system and automated control over dissolved oxygen.... After the first year of operation, Parker found the plant’s annual electricity use had dropped by 12.5 percent (21,500 kWh)."

How to Design & Control Waterside Economizers

ASHRAE Journal, Jun 2014, by Steven T. Taylor.
http://tinyurl.com/nkt8x2x

"ASHRAE/IES Standard 90.1 requires either airside economizers or waterside economizers for most cooling system applications. Air economizers are more common and almost always more energy efficient. But there are some applications where water economizers are preferred."

Energy Management and Water Heating Systems

Consulting-Specifying Engineer, May 2014, by Peter D. Zak.
http://www.csemag.com/single-article/energy-management-and-water-heating-systems/ead2ce605965e4cf773a4842cb5ee1b0.html

"Over the years, HVAC engineers have been challenged to provide more efficient and sustainable designs that meet societal demands to reduce the overall carbon footprint of a facility. Performance guidelines provided by programs such as the U.S. Green Building Council, Green Globes, and Energy Star provide guidelines for energy efficiency, while agencies such as the Environmental Protection Agency (EPA) and the Dept. of Energy (DOE) establish compliance guidelines for commercial HVAC systems."

Fully Measuring the Non-Energy Dollar

ACEEE, May 29, 2014, by Christopher H. Russell.
http://aceee.org/blog/2014/05/fully-measuring-non-energy-dollar

"ACEEE is now building on earlier research to quantify the dollars provided by non-energy benefits. The ideal outcome is to amass sufficient data from past energy improvements to statistically infer non-energy benefits. We think this effort will require the collaboration of multiple utility jurisdictions, culling through the project feasibility data generated by past and future energy programs."
