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, there are no emissions released into the atmosphere *For more details, please refer to the PDF document or feel free to contact us.

This product is a power generation system that converts medium to low-temperature thermal energy into electrical energy using a simple and highly efficient thermodynamic cycle. Unlike the conventional Rankine cycle using steam, which is employed in thermal power plants, this system uses an organic fluid with a lower boiling point than water as the working medium. This allows for power generation even from low-temperature heat sources that have been difficult to utilize and often discarded. Furthermore, the working medium circulates within a sealed closed circuit, so it is not discharged outside the system. 【Features】 - Capable of recovering heat from medium to low temperatures - A rich lineup ranging from 30 to 500 kW - Environmentally friendly organic working medium - Small installation space required - Easy installation with a packaged module - No need for a designated boiler and turbine chief engineer for small binary power generation - Achieves energy savings and decarbonization by utilizing unused heat and energy *For more details, please refer to the PDF materials or feel free to contact us.
