Single stage radial compressors

Siemens Energy offers a comprehensive range of single-stage turbo-compressors for applications in the metallurgical, oil and gas and chemical industries. These single-stage radial compressors are offered in a variety of designs. They can be configured with separate or integrated gearboxes, or as directly driven units. This allows to perfectly match the compressor with a wide range of prime movers including steam turbines and electric motors to meet customer preferences and specific site conditions.

High flow, high efficiency impeller technology
High-speed balancing ensures long time uninterrupted operation
Hirth-serration connection between impeller and shaft eliminates the need for re-balancing after rotor disassembly
Horizontal split gearbox casing enables easy access in case of maintenance (where applicable)
Compact design option for steam turbine driven units (direct drive)
Compliance with API standards where required

Our single stage centrifugal compressor is the perfect fit for atmospheric air compression at low pressure ratios. It covers a large flow range from small to very high volumes of up to 1.000.000 m3/h. This compressor uses well proven components from our integral geared compressor line and is designed in accordance with API 617. State-of-the-art aerodynamic parts allow a compact, single stage design. If necessary, an external gear box is used to match the driver speed. This modular design offers the advantage of an unchanged compressor design irrespective whether the machine is driven by a steam turbine, gas turbine or electric motor.
