ST Turbo Compressor

ST series: Single stage turbocompressors with integrated steam turbine driver.​

​The ST series is a range of integral turbo compressor / steam turbine-units with single shaft design. This compact design - impeller and turbine wheel are supported on a single rotor stand, with no coupling and gearbox - ensures very low steam consumption, high efficiency, low maintenance requirements and smallest footprint size.

Gas flows up to 150,000 m³/h can be handled.

This machine range serves demanding duties in process gas or air service, even in harsh environments. It provides state-of-the-art safety and reliability at lowest lifecycle costs to their owners, along with minimised initial capital expenditure.

This machine range is optionally available in a design compliant to API Std 617 engineering practices and testing requirements.
