Industrial Utility Efficiency    

Air Compressors

Helium is a precious noble gas that has become invaluable for leak detection, as well as cooling down magnets in medical equipment. This is why consumption of this essential industrial resource is increasing and its price is rising rapidly. To combat a looming shortage of this increasingly scarce resource, new methods of helium recovery are becoming more important than ever – as are specialized compressors for the same purpose.
Held September 16-19, 2018 in Chicago, the first-ever event drew 750 attendees who came together to learn and share ideas about the countless ways to achieve efficiencies with compressed air, blower, vacuum and cooling systems – and in the process – save energy and improve profitability.
Compressed Air Best Practices® Magazine interviewed Bob Groendyke, Vice President and General Manager, of Hertz Kompressoren USA. Hertz Kompressoren USA is headquartered in Charlotte, N.C. We’re a premium brand of the Dalgakiran Group Company, a leading international compressed air sales and service producer with a well-established worldwide network. Our parent company was founded in in Turkey more than 50 years ago and currently sells and services machines in 130 countries. Hertz Kompressoren has built a solid reputation by creating and manufacturing high-quality products offered at reasonable prices to satisfy our worldwide customer base.
Measuring the Free Air Delivery (FAD) of an air compressor can be challenging. With a proper flow meter and some mathematics this task is manageable. This article sheds some light on how to select the flow meter and summarizes parameters to be considered in the FAD measurement task.
The 2018 AICD Annual Meeting and Exhibition was held May 20-22 at the Hyatt Hill Country Resort in San Antonio, Texas.  The membership of the Association of Independent Compressor Distributors came together under the theme of “Roundin’ up New Business.”  “AICD membership has doubled over the past three years,” said AICD President Phil Kruger (Harris Equipment). “After selling out exhibit space in 2018, we believe our direction focused on serving the needs equally, of both vendors and members at our conference, is working.”
In an ideal world, we would all have plenty of space, time and money to create the perfect compressed air system. In practice, we have to balance our ideals versus what we can actually accomplish. Compressed air systems take considerable forethought and planning to achieve a perfect install; however, we can use some key takeaways from this article even if we are ever faced a less than ideal installation. Remember to keep the compressors cool, minimize piping pressure drop and to allow sufficient room around the equipment for service.
This article is going to identify two air compressor control situations that will preclude translating air use reduction in the production area into lower input energy into the air compressor.
The plant produces both molded and blow molded plastic parts on a 5 day per week, three shift schedule. Production and maintenance sometimes occurs on weekends, occasionally requiring the air compressors to run on a 24 x 7 basis so the practice was to leave the compressed air system always pressurized. The system consisted of three modulating lubricated screw compressors one sized at 150 hp and the others 125 hp (3 units), each controlled with their local compressor controllers.
A spectacular vision is gradually becoming reality in Cadarache in the south of France. Modeled on the sun, the ITER (International Thermonuclear Experimental Reactor) fusion system uses nuclear fusion to generate energy in order to secure humanity’s supply of electricity. One of the biggest challenges is the high temperature inside the reactor. Technology by Sauer Compressors is a key factor in cooling the reactor. The manufacturer has supplied the world’s largest system for helium recovery.
Compressed Air Best Practices interviewed Timo Pulkki (CEO), Hannu Heinonen (President, Tamturbo Inc.) and Mike Batchelor (Director of Sales Americas) from Tamturbo. Since the 1960’s, the Tampere region in Finland has been a birthplace of several air compressor innovations – many of which involved Kimmo Laine, a co-founder of Tamturbo. Mr. Laine was a leader in R&D in the air compressor business for many years since the 1960s. This included bringing a high-speed turbo air compressor to market later at Tamturbo. Working together in the 1980’s in a division of Tamrock, called Tamrotor-where Hannu Heinonen also worked, Mr. Laine met a gentleman named Jaakko Säiläkivi.
Today’s industrial manufacturing environment is extremely competitive, requiring companies to constantly search for cost saving opportunities and better efficiencies. In many cases, manufacturers find that centrifugal air compressors are a successful method for reducing the overall plant costs involved in supplying compressed air.
