The ST Series


The ST series is a range of integral single-stage centrifugal turbo compressor / steam turbine-units with single shaft design. Its compact design features a semi-open overhung impeller (3D design) and turbine wheel, supported on a single rotor stand, without coupling or gearbox. This ensures very low steam consumption, low maintenance requirements and smallest footprint size, while operating in harsh environments. The ST series serves demanding duties in its industries - like compression of corrosive, erosive and sticky gases or process gas or air service applications.

Gas flows up to 200,000 m³/h can be handled. The machine provides state-of-the-art safety and reliability at lowest lifecycle costs to their owners, along with minimised initial capital expenditure.

It is optionally available in a design compliant to API Standard 617 engineering practices and testing requirements.
