The minimum operating temperature is 90 °C, and it can complement the electrical generation with the production of useful heat with temperatures of up to 50 °C. When the heat source temperature of the ORC machine is between 120 °C and 150 °C, Rank® MT equipment offers excellent electrical performance.

η=WnetQin=1−QoutQin. The basic Rankine cycle is presented in terms of temperature and entropy change in Figure 10.2. The ideal state of this cycle is reflected in the vertical lines 1-2 and 3-4, when the fluid compressed and expanded. Those processes are shown to proceed isentropically, i.e., without entropy change.

An Organic Rankine Cycle (ORC) system is a closed thermodynamic cycle used for power production from low to medium-high temperature heat sources ranging from 80 to 400°C and for small-medium applications at any temperature level.

The ORC is a thermodynamic cycle that converts low-grade heat, such as waste heat from boilers, furnaces, engines, or solar collectors, into useful mechanical work or electricity.
