Air Compressors

Properly sizing a compressed air system can help determine if your facility has enough air to adequately supply your production equipment. Designing a cost effective system that minimizes any interruptions to productivity requires thoughtful planning and design. Typically, the desired outcomes of such a system focus on stable pressure and efficient operation, though it is important to note that each of these elements requires a unique solution. This article will provide guidance in proper selection considerations and suggest when a centrifugal air compressor may be ideal for your needs.
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.
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.
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.
The air we breathe and the air compressors ingest is a mixture of gases, aerosols, biological material, and particulates. It’s a real mess! Particulate, for instance, is very harmful to humans, because lungs are complex oxygen separators, not filters. They tend to load up with particulate, this is harmful over time. There isn’t a sufficient “pre-filter” to prevent all harmful particulate from entering the lungs. However, humans prefer water in the air, gas, aerosol, and to a certain level, liquid form. A de-humidifier would not typically be a healthy addition to our built environments.
