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.

What is the temperature range of the organic Rankine cycle?
Applicable fluid heat sources are between 70°C and 150°C. Gaseous heat sources above 150°C can also be used with the deployment of a secondary heat exchange loop. Our low-temperature ORC solutions use hot water as fuel in order to generate up to 125 kWe of clean electricity, at no additional cost to the operator.
What temperature does Rankine cycle work at?
The Rankine cycle applied using a supercritical fluid combines the concepts of heat regeneration and supercritical Rankine cycle into a unified process called the regenerative supercritical cycle (RGSC). It is optimised for temperature sources 125–450 °C.
What is the range of Rankine cycle?
Technology | Power Cycle | Performance Level |
Steam turbine | Rankine cycle | 30-40% |
Gas turbine | Brayton cycle | 30-40% |
Combined cycle | Brayton topping/Rankine bottoming Diesel cycle | 45-60% |
Diesel | Diesel cycle | 40-50% |
What is the minimum temperature for ORC?
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.
