A binary power generation system that can generate electricity with water at around 70 degrees Celsius.
The rotary heat engine is a system that incorporates a Wankel-type rotary expander (developed in-house) into a Rankine cycle system's expander. Unlike conventional expanders, the Wankel-type rotary expander utilizes static pressure to convert it into rotational power, allowing it to operate efficiently even at low pressures. The waste heat, which is low-temperature and has low energy value, can be converted into high-value energy by transforming it into electricity. This technology is patented in Japan, China, the EU, and the USA.

Company information
While it is easy to 'transfer heat,' it is very difficult to 'transport heat.' We propose methods and technologies to transport heat from the heat source to where it is needed. Additionally, we are working on thermoelectric generation as a research project within our company.
