The Advantages of Onsite Nitrogen Generation for Brewers

Compressed Air Best Practices, Oct. 2016, by Mike Robinson.

"Although the basic principles behind brewing are little changed since their advent, the technological aspects are much improved. Today, large stainless steel tanks are used for fermentation and wort aeration, and complex, automated systems help with everything from temperature regulation to bottling. A price tag comes with these high-tech systems, and it’s not insignificant. By using onsite nitrogen generation, brewers can save significant amounts of money throughout the life of their operation."

New CSA C837-16 [Canadian] Compressed Air Efficiency Standard

Compressed Air Best Practices, Oct. 2016.

"After almost three and a half years of development work the Canadian Standards Association C837-16 document “Monitoring and Energy Performance of Compressed Air Systems” has finally been published and is available for download."

Sparks Dynamics Optimizes NIST Compressed Air System

Compressed Air Best Practices, Aug. 2016, by Mac Mottley.

"Sparks Dynamics, a leading cloud based remote monitoring and data analytics technology company, entered into a Cooperative Research and Development Agreement (CRADA) with NIST researchers to develop industrial compressed air pattern analysis to enhance system efficiency and reliability."

The Importance of Bi-directional Compressed Air Flow Measurement

Compressed Air Best Practices, Aug. 2016, by Pascal van Putten.

"Technology is available which enables a compressed air flow meter to measure not only the magnitude of the flow, but also the direction. Why is this important? In this article we will describe two case studies where bi-directional compressed air flow measurement plays a key role to come to the right conclusions."

A Compressed Air Piping System Assessment

Compressed Air Best Practices, June 2016, by Gary Wamsely.

"During an Energy Review at a relatively new health care garment factory, in the Southwest, we found all three of the 100 psig nominally rated rotary screw air compressors were operating at 115-120 psig continuously. We asked the Production Superintendent if this was normal or if something had recently changed. He explained that initially they operated two air compressors but had to begin running the 3rd unit in ‘trim’ mode after some converting machines were up-graded. Then, a new larger converting machine was recently installed and air pressure quickly became a production issue. Since capital funds were tight, the project engineering team determined the third air compressor had sufficient capacity."

Don’t Skip the Most Important Meeting of Your Energy Project

Compressed Air Best Practices, May 2016, by John Molnar.

"A meeting between the auditor, incenting organization, vendor, and end user can help maximize the benefits of any energy-saving project."

Cooking Oil Factory Combines Compressed Air Systems to Save 36%

Compressed Air Best Practices, Apr. 2016, by Ron Marshall.

"To produce healthy, high-quality cooking oil, this food processing company crushes and processes oil seeds shipped in from local farms. To increase the energy efficiency of its oil seed crushing and processing facility, the company optimized its compressed air system by combining three separate systems into one."

Innovative Energy Program Assessments at Darigold

Compressed Air Best Practices, Apr. 2016, by Clinton Shaffer.

"Darigold, a farmer-owned dairy co-op located in the Pacific Northwest, has the happy cows, but production is more sophisticated. The company has eleven state-of-the-art production facilities churning out high-quality dairy products at mind-boggling rates. To maintain efficient production at scale, Darigold also has an innovative energy management program in place."

Innovative Blow Molds Reduce Compressed Air Pressure in PET Blow Molding

Compressed Air Best Practices, Mar. 2016, by Vincent Duvernois,  Stephane Larcade, and Jean Pilnard.

"Technological trends in plastics manufacturing are driving the costs of production down. In industrial PET blow molding specifically, two innovative techniques have had major impacts over the last 15 years: “light weighting” the plastic bottles, and recirculating high-pressure compressed air. Both have helped to improve the energy efficiency of PET blow molding by reducing compressed air requirements dramatically."

Is Your Desiccant Dryer Running Efficiently?

Plant Services, Jan. 2016, by Ron Marshall.

"Pity the neglected air dryer: Much time and attention is paid to efficiently controlling air compressors, but often the control of air dryers gets ignored. If your plant has desiccant dryers, it's important to manage their operation effectively, too, in order to get the maximum return from your compressed-air efficiency efforts."
