The organic Rankine cycle (ORC) that we handle is a system based on a simple and highly efficient thermodynamic cycle, ideal for converting medium to low temperature (above 86°C) thermal energy into electrical energy. This cycle, invented by a Scottish physicist who is one of the founders of thermodynamics, operates in a closed loop and does not release any emissions to the outside environment. The surplus heat (Qout) released in the condenser can be directly utilized for other purposes, such as preheating or drying fuel as a heat source. 【Features】 ■ Simple, compact, and highly reliable ■ Capable of utilizing heat sources even at relatively low temperatures ■ As it is a sealed closed circuit, no emissions are generated into the atmosphere *For more details, please refer to the PDF document or feel free to contact us.
