The screw-rotor steam engine possesses the following advantages in comparison with steam turbines:
1. High reliability and long life potential that is defined by simplicity of its massive design
2. Small dimensions in size and in weight that allow erecting a STEAMASTER even in already existing facilities with limited footprint
3. Tolerance to deviation of steam quantity and quality
4. Quick start up and stopping procedure
5. Higher internal relative efficiency (67 ^ 70 %)
6. Extreme simplicity of service
7. Very low operation costs
8. Oil free output steam
9. Skid-mounted and modular structure allows
Easy installation and easy increase of capacity
10. Very quick return of investment.
