Turbo compressors with integrated gearboxes

The oil-free turbo compressors in AERZEN’s CC series are characterised by high stage efficiencies, smooth running and excellent adjustability, and meet the most stringent requirements for availability and process safety. They are rated for a wide range of process gases and gaseous mixtures – including corrosive, toxic and flammable substances – and are configured on a project-by-project basis.

Integrated gearbox for high performance density
The integrated gearbox technology, featuring a central main gear and separate pinion shafts, enables the speed of the individual compressor

stages to be adjusted to suit specific applications. This allows the stages to be specifically tuned with their respective operating and compression ratios. The result is high efficiency, a

compact design and energy-efficient operation, even under demanding process conditions. Electric motors and steam turbines can be used as drivers.

System expertise in development and manufacturing
Our own R&D centre and in-house manufacturing capability enable application-specific

adaptations with a short time-to-market. Aerzen Process Gas GmbH is responsible for the design and rating of the turbo compressors, including all auxiliary packages. The impellers are manufactured in-house and the rotors are dynamically balanced. The compressors are then fully assembled and inspected. In addition, customised oil systems, technical solutions for gastight seals, as well as PLC programming and measurement technology are developed and integrated in-house. Compliance with API, ASME, DIN and other relevant industry standards is ensured in accordance with the customers’ specifications.

Wide range of applications
The Turbo portfolio for the process gas industry includes both compressor units with bare shaft ends (core units) and complete systems,

including peripheral equipment. Typical applications can be found in the oil and gas industries, steel production, power plant technology, chemical and process engineering and in hydrogen and CO₂ processing. In particular large-scale industrial plants in continuous operation with high volume flows and high pressures benefit from the technological advantages of turbo compressors.

In the case of process gas compressors, unplanned downtime can quickly lead to high costs. As a standby unit is frequently not available, fast reaction times are particularly important in the event of a service call. AERZEN supports operators by providing rapid technical assistance to resolve issues promptly and to secure system availability.

Turbo solutions for a wide range of requirements
In addition to gearbox-driven turbo compressors, AERZEN offers a range of other turbo technologies for demanding process gas compression. The solutions cover pressures of up to 300 bar and volume flows of up to 350,000 m³/h.
