Market Position/ History

Atlas Copco Group was founded in 1873 and is headquartered in Stockholm, Sweden.

Initially, the company focused on manufacturing railroad equipment, particularly steam engines, before expanding into other areas of machinery. In the early 1900s, Atlas Copco began producing air compressors, a move that would set the foundation for its future success in industrial equipment manufacturing. The company’s name, "Atlas Copco," reflects its origins, with "Atlas" referring to the ancient Greek titan and "Copco" an abbreviation of "Compagnie Pneumatique Commerciale," emphasizing its early focus on pneumatic technology.

By the 1980s and 1990s, Atlas Copco had solidified its reputation for high-quality products and began acquiring several key businesses to further expand its reach. Notable acquisitions during this period included companies in vacuum technology, air compressor systems, and industrial power tools, all of which helped to diversify and strengthen its business portfolio.

High-Efficiency Impellers

High efficiency is a fundamental requirement for all processes involving turboexpanders. Company achieves this performance through the use of the latest technology tools and a vast experience base.

Precision That Meets Your Needs

To ensure top efficiency, we utilize computational-fluid dynamics (CFD) and finite-element analysis (FEA) in the design of our impellers, and the latest 5-axis computer-aided manufacturing processes. As an established turbomachinery manufacturer, we can choose from a wide variety of proven impeller designs in our data base to precisely match clients process needs. This combination of experience and technology ensures that our customers receive maximum efficiency and the most reliable impellers available in the industry.

Variable Inlet-Guide Vanes

To compensate for the varying operating conditions found in many processes, turboexpanders must deliver efficient off-design performance. Atlas Copco turboexpanders use variable inlet-guide vanes (IGVs) engineered to produce optimum flow patterns and provide precise, continuous control across the full range of operation.

Full Control Over Your Process

Apart from an optimal control range and excellent efficiency for all parts, our IGVs feature a wide range of regulation capabilities and excellent partial performance. Combined configuration ensures maximum control flexibility.

Bearing Systems

Atlas Copco Gas and Process bearing designs include hydrodynamic bearings as well as Active Magnetic Bearings. Final bearing selections are made specifically for your process applications.

Oil Bearings

The company offer horizontally-split, high-speed pinion bearings featuring five self-centering pads that ensure stable rotation. Horizontally-split bearings are especially easy to inspect and maintain. Tilting-pad bearings, which are used on high-speed shafts, and sleeve bearings, used on low-speed shafts, ensure reliable performance, efficiency, and optimal speeds for each process.

Active Magnetic Bearings

Atlas Copco also offers designs using active magnetic bearings. Active Magnetic Bearings generate a magnetic field to align the shaft in its centerline. This eliminates friction and the need of lubrication. The electromagnets of Active Magnetic Bearings are controlled with rotor position sensors by a digital control cabinet. The resulting combination of lower maintenance, higher reliability, and increased durability boosts equipment performance. Its dedicated service team supports customers at every step, before and after installation.

Hydraulic-braked expanders

Expander is braked by the presence of oil in the chambers surrounding the rotor shaft.
