Centrifugal Compressors

Hengelo, The Netherlands: On the leading edge of advanced manufacturing

Industrial Revolutions are rather momentous events. Most historians count three such periods. The mechanization of manual work using water and steam power triggered the first Industrial Revolution, while the harnessing of electricity and mass production (Henry Ford often cited as the pacesetter) drove the second Industrial Revolution in the early 20th century. The computer set […]

Highest efficiencies for air separation and process industries

The STC-GV centrifugal compressor series has been meeting compression demands for more than 60 years. Scarce resources and stringent environmental regulations require efficient products to meet global demand for fuel and hydrocarbon products. It’s a given that compressor trains are at the core of almost any process operation. When selecting a compressor to produce, transport […]

World’s largest geared compressor rotor manufactured in Duisburg

Siemens manufactured and tested the world’s largest geared compressor rotor at its Duisburg, Germany facility. With a diameter of 1.8 meters (5.9 feet), the first-stage impeller is the largest installed on an integral-geared compressor rotor. The impeller was balanced in Duisburg at a speed of 3,970 revolutions per minute. At its average operating speed, the […]

Duisburg, Germany: where the Ruhr meets the Rhine

Editor’s Note: Over the years, Siemens has acquired several well-known suppliers in the compressor segment, including Mannesmann Demag, Demag Delaval, Delaval-Stork, Delaval, Kühnle, Kopp & Kausch (KK&K), PGW Turbo, and most recently, Dresser-Rand. Today, the Duisburg, Germany site is a major operation within the Dresser-Rand business, part of Siemens Power and Gas Division. Chimneys, industrial […]

Largest Pipe Array Ever Built Reducing Noise Pollution in the North Sea

Our pipe resonator array is a proven technology for reducing turbo compressor noise at the source. Last year, we successfully tested a 30-inch pipe array, the largest ever built, in Le Havre, France. Turbo compressors are, by nature, a loud noise source because of the high power and speed. Most compressors produce a strong tonal […]
