Course Description

Elliott Compressors and Steam Turbines

Course objective

With a detailed Technical Training course using demonstration, the attendees will get knowledge about safe and effective operation, maintenance and electrical instrumentation & control tailored to different types of Elliott compressors.

In addition a Basic Technology Training Thermodynamics Operation Maintenance the attendees can refresh and update general knowledge in the field of Elliott industrial steam turbines and will get knowledge about the most up-to-date findings and technologies in the industrial steam turbine sector.

Course structure

This training program is designed to instruct attendees in a broad range of subjects, such as basic design of compressors, compressors operation, instrumentation and specific maintenance routines.

To improve the practical knowledge, the trainees will use our Interactive Compressor Training Program. The program includes the start-up procedure, normal running, troubleshooting and the shut-down procedure. During normal running the trainee can vary process parameters and study the effect on the compressor performance.

This Basic Technology Training program is designed to instruct attendees in a broad range of subjects, such as basic design of the equipment, principles of steam turbine operation, instrumentation and specific maintenance.


Course duration: 5 days.

Who should attend?

Personnel moving into the industry Experienced operational, maintenance or instrumentation personnel recent graduates, other engineers.
