In the conversion of low temperature heat into electricity the greatest efficiency is obtained in many cases by using an organic Rankine cycle (ORC). This paper deals with an ORC-design, in which a high-speed oil free turbogenerator-feed pump is used. Freedom from oil significantly increases the thermal stability of the organic fluid and makes a hermetic design possible.
