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, pressure-lubricated sleeve 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 optimized auxiliaries guarantee highest efficiency. Adjustable guide vane units at the first or at all compression stages optimize the operating range. External cooler arrangements do not limit i. e. with extreme site conditions and cooler materials.
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.
