Industrial Utility Efficiency

Air Compressors

Room temperature, or ambient temperature, has a significant effect on plant operation. The amount of space, or lack thereof, for compressed air equipment and the cooling flow all have an important impact on plant operation; because if the air compressors are down; so are you!

Variable Inlet Guide Vanes Boost Centrifugal Air Compressor Efficiency

Compressed Air Best Practices® (CABP) Magazine recently caught up with the Compressed Air and Gas Institute (CAGI) 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.

How Inlet Conditions Impact Centrifugal Air Compressor Performance

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.

Centrifugal Air Compressor Basics: Deciphering Manufacturer Performance Curves

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.

11 Key Considerations For Selecting a PET Air Compressor System

In 1979 I received a call from a business friend that had just purchased his first single-stage base cup blow machine. He was surprised to find out that he actually needed something more than 100 psi of plant air to blow bottles. This was my entry into engineering a polyethylene terephthalate (PET) compressor system. Since then, I have engineered and delivered over 350 systems—from Tobago to Tibet—and many locations in between.

Acrylon Plastics Optimizes Compressed Air Supply

Acrylon Plastics located in Winkler, Manitoba, Canada manufactures an extensive variety of custom plastic parts for a wide range of end use applications. Years ago changes to their production volumes increased the compressed air flows to above what their compressed air system could deliver. As a result the plant pressure would fall to low levels during production peak demands, which negatively affected sensitive compressed air powered machines. In addition to this during light plant loading conditions the air compressors would run inefficiently. Plant personnel tried a variety of strategies to deal with the plant peaks, with the most efficient solution coming as a result of installing VSD style compressors and pressure/flow control.

Sidel and Krones Blow Molders Stretch Conservation Potential

The beverage industry has been using polyethylene terephthalate (PET) 2-liter plastic bottles primarily for packaging carbonated soft drinks since the 1970s. As that market has grown to encompass bottled drinking water, stretch blow-molding machines continue to produce those plastic bottles. The concept is simple: A pre-form plug is inserted into the blow molding machine heated, and compressed air is injected, “blowing” into the pre-form to create the bottle.

Sullair Celebrates 50 Years of Air Compressor Excellence

A culture change is in the air at Sullair, a pioneer in air compressor technology, as the company celebrates its 50th anniversary. A global manufacturer of rotary screw air compressors used to power air-driven industrial equipment and tools used in manufacturing as well as the energy, mining and chemicals industries, Sullair operates five manufacturing facilities worldwide.

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.

Foundry Air Compressors Out of Control

Quite a number of worst-case compressed air scenarios have been encountered over the years but none may compare to the conditions that existed in a metal foundry somewhere in North America. For reasons you are about to discover, we will not reveal the name of this factory or its location, in order to protect the innocent from embarrassment.

Sullair of Houston Provides Air Compressor Solutions for Extreme Environments

Sullair of Houston, one of the largest North American distributors of Sullair industrial and portable diesel compressors, loves a challenge. The company designs customized air compressor packages that fit the rough and rugged world outside the walls of an industrial plant. It builds air compressor solutions that operate efficiently in extreme, harsh environments around the globe. This includes offshore or marine environments, high or low ambient conditions—any environment where a standard air compressor will not operate safely or efficiently.
