During my forty years of involvement with distribution (companies that sell and service compressed air system products) as a Vice President of Sales and Marketing and Account Manager, I have witnessed a tremendous amount of change in the compressed air industry. As much as we like to reminisce about the good old days, it is quite apparent that the resources, capabilities and knowledge of distribution today are significantly better than ever before.
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.
In our discussions with Stephen Titus and James Bowers, National Sales Manager of Titus Air Systems, we talked about several examples of how The Titus Company provided custom-engineered solutions to various customers. The diversity and complexity of these jobs exemplify how The Titus Company has grown from a small distributorship operating out of a townhome to a thriving compressed air and gas solutions provider capable of tackling highly nuanced applications.
High speed bearing technology is applicable for aeration blowers operating at much higher speeds than the typical 60Hz, 3600RPM for cast multistage units. High Speed Turbo (HST) units are usually single stage (though some utilize multiple cores) and rotate from 15,000 to 50,000RPM. At such high speeds, standard roller bearings cannot offer the industry standard L10 bearing life. Two types of bearing technologies have come to dominate the wastewater treatment market for these types of machines: airfoil and magnetically levitated. Often the two technologies are compared as equals, however, in many significant ways they are not.

The company prides itself on being client-focused with a commitment to respond to service needs 24/7. “Our relationship with clients involves more than us just selling equipment, parts and maintenance. We provide system auditing, training, testing and information about innovations in our industry,” says Michael McCulley, president.
“Jurassic Park,” Michael Crichton’s 1990 novel about a theme park full of genetically engineered dinosaurs, circles around one central theme — control. In fact, there are literally nine chapters titled “Control,” and most of those chapters follow the brilliant, chain-smoking systems engineer John Arnold as he ravenously tries to restore the control systems after a catastrophic collapse.
Productivity is more reliable when equipment can be monitored to detect incipient failures and take corrective action before the plant goes down. But many devices, such as analog control valves, pneumatic valve terminals and field sensors, often do not offer diagnostic feedback, or it is not being used. This white paper describes how this problem is being addressed, and includes an example of pneumatic valve terminals that can monitor, among other things, open load or coil currents at the specific valve and pressure inside the valve terminal.
It’s one thing to move materials during the production process, but when it’s a finished product on the packaging line, choosing the right material handling system is essential. Getting it wrong results in squandered production time when product loss occurs, and wasted raw materials.
There are six basic types of cooling systems that you can choose from to meet the cooling needs of your load. Each one has its strengths and weaknesses. This article was written to identify the different types of cooling systems and identify their strengths and weaknesses so that you can make an informed choice based on your needs.
As a reader of this journal, you are well aware that large compressed air systems often have significant wasted air — often from leaks — that represent tens of thousands of dollars of waste per year. However, it is our experience that the so-called “low-cost” measures identified often go un-repaired, while other more costly capital projects get funded. Why? With an ROI of a half year or less, they seem like IQ tests to many compressed air auditors.
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.
Many thousands of dollars of annual electrical savings are being achieved worldwide using special purge reduction controls on desiccant air dryers. These controls reduce the expensive purge air that must flow through the dryer to regenerate the desiccant beds. But, unexpected problems with these controls can cause hidden problems that can reduce or eliminate the savings.
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.
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.”
In general, this article focuses on the operating principles of centrifugal air compressors, discussing them in simple terms to provide an understanding of application limitations and opportunities. One primary goal is to define often-confusing terminology, such as “rise to surge,” stonewall and surge,” “mass flow,” and “dynamic compression.” This article is not intended to be an engineering discussion of the various types and designs of centrifugal and other air compressors, but rather, a guideline for deciphering operating curves and understanding general performance.
There are many distributors in the industrial air compressor industry that are very concerned about the future role of distribution—or, more specifically—if there even is a role for distribution in the new business environment. The industry has changed, and doing business in the current environment is very different from what distribution has become accustomed to. You may describe it as a “changing of the paradigm” or “moving the cheese,” but make no mistake—it has changed drastically. There are examples of progressive distributors that have succeeded in managing change and have adapted their business strategy accordingly.
From Dehumidification to Siloxane: Parker Biogas Purification - The Importance of Removing Contaminants from Biogas
Biogas is an extremely valuable energy source. Originating from biomass, sewage, plants and landfill sites, it is gaining ever-increasing worldwide recognition as a premium source of renewable energy. It is also making a major contribution to the global energy supply mix by replacing existing fossil-fuel sources such as coal, oil and conventional natural gas.
Plug an electrical device into an outlet. Does it work? Great! For some people that’s all that matters. When it comes to compressed air, many manufacturing plants operate the same way. As long as there is enough air, that’s all that matters. But what if cost control also matters to your company? Smart compressed air users may already know how much air they’re producing, but they also want to know how much air they’re using—and whether they’re using it productively. To find out, they’re taking accurate, real-time measurements using flow meters.
