As an industrial distributor for 65 years, C.H. Reed, Inc. has been providing ideas, concepts and sustainable solutions to help manage issues associated with three key areas of industrial plants: compressed air systems and equipment; assembly tools and ergonomic material handling; paint finishing and fluid handling equipment. Compressed air has always been a strong focus for C.H. Reed, and it’s a common thread running through all of its product families.
Compressed Air Best Practices® Magazine and the Compressed Air and Gas Institute have been cooperating on educating readers on the design, features, and benefits of centrifugal compressor systems. As part of this series, Compressed Air Best Practices® (CABP) Magazine recently caught up with Rick Stasyshan, Compressed Air and Gas Institute’s (CAGI) Technical Consultant, and Ian MacLeod of CAGI member company, Ingersoll Rand. During our discussion, we reviewed some of the things readers should consider when installing a centrifugal compressor system.
Air-operated double diaphragm (AODD) pumps are common to many manufacturing facilities. As estimated by veteran compressed air auditor Hank van Ormer of Air Power USA, approximately 85 to 90 percent of plants in the United States have AODD pumps. They are used for all kinds of liquid transfer applications, like those found in chemical manufacturing, wastewater removal, and pumping viscous food products.
The World Energy Engineering Conference provides many educational tracks for energy managers to attend, including several hosted by the Environmental Protection Agency’s ENERGY STAR® program and the Department of Energy’s Better Buildings, Better Plants Program. I was fortunate to sit in on several of the Industrial Energy Management tracks, in which energy mangers from companies like Raytheon, Nissan North America, and General Mills shared success stories and strategies for running energy management programs.
The 2015 Association of Independent Compressor Distributors (AICD) Membership Conference & Exhibition
The speaker line-up is vendor-neutral and structured to help air compressor sales and service companies improve their businesses. Presentations included an economist updating members on the state of the economy, a utility incentive program update from Clear Result, and a Q&A Session featuring Ron Nordby and Bill Scales.
Centrifugal compressors are dynamic, and each has a characteristic curve of rising pressure as capacity decreases. Without any control system, the compressor would operate along this natural curve. A centrifugal compressor's flow and pressure are typically controlled by a combination of an inlet control device and an unloading valve (UV).
The introduction of rotary screw air compressors controlled by variable speed drives (VSDs) is one of the best energy efficiency innovations introduced to the industry in the past few years. This style of compressor control can significantly reduce the energy wasted by compressors running in the unloaded condition. But the type of VSD control offered by various manufacturers can differ, and some of these differences can affect the efficiency of the system. This article discusses some little known tweaks to VSD compressor control, including some using hidden features that can sometimes be implemented to enhance the savings gained by the installation of this type of compressors.
Compressed Air Best Practices® Magazine recently caught up with Rick Stasyshan, the Compressed Air and Gas Institute’s (CAGI) Technical Consultant, and John Kassin of Cameron to discuss variable inlet guide vanes (IGV). The following interview describes how centrifugal compressor efficiency can be improved thanks to recent developments in IGV technology.
As the 21st century progresses, the environment is becoming very unsettling for distribution in the industrial air compressor industry. The forces of change discussed in Part 1 of this two-part series created a situation very unfamiliar to distribution. The stability experienced by the industry from 1960 to 1990 was displaced by the volatility of the last 25 years. Consolidation of manufacturers and distributors, loss of channel power, evolution of hybrid channels to market, and intense pressure on profitability are just a few of the major forces distribution has had to deal with. Distribution’s tentative reaction to these forces has resulted in both distributors and manufacturers questioning the long-term viability and relevance of distribution in the industrial air compressor industry.
Compressed Air Best Practices® (CABP) Magazine recently spoke with Rick Stasyshan, Compressed Air and Gas Institute’s (CAGI) Technical Consultant, and Mr. Neil Breedlove of CAGI's Centrifugal Compressor Section and member company, Atlas Copco Compressors, about centrifugal air compressors. Specifically, the discussion outlined how various inlet conditions can impact the performance of centrifugal air compressors.
Hannover Messe 2015 attracted 220,000 visitors with 70,000 coming from outside Germany. The show placed a major emphasis on the digitization of manufacturing. Deutsche Messe Board Member Dr. Joachim Kockler said, “Industry 4.0 has arrived. Digital integration is becoming a key aspect of modern manufacturing and this trend is set to continue at a rapid pace.” It is clear our sector is investing in the “Industry 4.0” trend allowing compressed air system key performance indicators to be captured and managed. The goal of this article is to provide readers with a sampling of highlights catching my eye at the show – with apologies to the many companies left out due to editorial space limitations.
