STC-GV, STC-GVT Siemens Turbocompressor – Integrally Geared, Vertically split volute casing
A success story since 1948
Since its inception 60 years ago, the STC-GV compressor series has been meeting demands for compression solutions with high efficiencies and pressures up to 200 bar. STC-GV compressors, designed according to customer specifications and in accordance with both API 617 and
API 672, guarantee the highest quality and technical standards for a broad range of industrial application.
An innovative and compact design allows for an integrated turbine drive within STC-GV, where compressor stages and turbine are mounted on the same gear (STC-GVT).

Integrally geared centrifugal compressor with vertically split volute casing (STC-GV)
Siemens Turbocompressors
Answers for energy.
Design Concept
Powerful, robust and reliable
The STC-GV integrally geared centrifugal compressors feature a multi-shaft arrangement with different speeds. All shafts are mounted in maintenance-free, oil-lubri- cated hydrodynamic bearings. With up to eight compressor stages around a central bull gear, the STC-GV compressor series forms a compact unit for the multi-stage compression of a wide range of gases.
Optimized shaft speeds, modern impellers, tailored aerodynamics and mechanics along with optimized auxiliaries guarantee the highest efficiency. Adjustable guide vane units at the first and/or any other compression stage optimize the operating range. External cooler arrangements allow for operation at extreme site conditions.
Package and driver options
For most STC-GV compressor sizes, Siemens offers a package design. The package includes the compressor, driver, process gas coolers, lube oil console, process piping and all tubing and wiring. The package design leads to significantly reduced on-site installation time. These compressor types are also suitable for direct turbine-drive or integrated turbine design (STC-GVT).
Driver: depending on process and energy resources: steam turbine, gas turbine or electric motor.
Siemens also offers variants of the STC-GV:
STC-GV (H): this compressor is designed for high-pressure application with suction pressures higher than 5 bar, especially booster air in air separation.
STC-GVT: a new and compact design, STC-GV is also available with integrated turbine drive, compressor stages and turbine being mounted on the same gear.
STC-GT: singleor multi-stage expanders enable power recovery from process gases.
STC-GVT: with its single or multiple expander stages, STC-GVT is the ideal solution for simultaneous gas compression and expansion of process gas.
