Back pressure steam turbines STG I
The turbines are only equipped with one turbine stage located on the shaft overhang and equipped with only one seal. The turbine stage is in two basic modifications - a radial stage and an axial stage. Alternatively, partial admission of the impeller is used.
They are characterized by their high efficiency in comparison with competing turbines of the same design thanks to a wide range of specially designed turbine stages.

Back pressure steam turbines STG II
These are double-shaft turbines with a high-pressure and low-pressure STG I module, which are connected in series and suitable for double-pressure steam boilers, as they allow steam to be supplied to the turbine at two pressure levels.
They are equipped with one turbine stage on each shaft. The stages are in two basic modifications - radial and axial. They are characterized by their high efficiency in comparison with competing turbines of the same design as well as multi-stage axial turbines in terms of parameters and price, thanks to a wide range of specially designed turbine stages.
