We have built expertise in designing, prototyping, and testing turbogenerator systems for various applications. Our internal research has explored different thermodynamic architectures for automotive, aeronautics, naval, and bus applications.
Currently, we are developing a high-efficiency and high-power-density turbogenerator based on the Intercooled Recuperative Reheat Gas Turbine (IRReGT) thermodynamic cycle.
Our turbogenerator system has a power range from 3 kWe (for small-scale concentrated solar power applications like Hélios) to over 150 kWe (for buses, trucks, and naval applications).
We are currently conducting comprehensive testing of this machine in our dedicated test bench facilities. Exergetica holds a license for more than 10 patents related to the IRReGT thermodynamic architecture, showcasing our commitment to innovation in this field.
Known also as the vapor cycle, Rankine machines use changing phase working fluid as a working medium to achieve the Rankine thermodynamic cycle. This cycle uses a pump, a boiler (evaporator), an expander, and a condenser.
Water is used for medium and high-temperature sources and organic fluids for low temperatures.
We have designed different Rankine systems
for low, medium, and high temperatures.
Different expansion machines have been developed including:
– Piston expander
– Turbocompressors
– Scroll and impulse turbines.

Stirling engines are external combustion engines that have versatile applications such as Auxiliary Power Units (APUs) and Waste Heat Recovery (WHR) machines.
These reversible engines can also function as heat pumps, converting electric power into both hot and cold temperatures.
Stirling machines offer numerous advantages:
At our company, we specialize in designing and developing Stirling engine prototypes for various applications. Our prototypes range in power from 2 kWe to 20 kWe. We have developed a high-efficiency and high-power-density Stirling machine based on a patented architecture, incorporating recuperative reheat technology. This machine is fully enclosed, and the electric generator is driven by a magnetic clutch, resulting in reduced emissions.
Thermoacoustic machines are external combustion and waste heat recovery systems that produce acoustic power.
These reversible machines can also be used as heat pumps, converting electric power into both hot and cold temperatures.
Thermoacoustic machines offer several advantages:
At our company, we specialize in designing and developing thermoacoustic prototypes for various applications, including main energy converters, APUs, waste heat recovery systems, and heat pumps. Our prototypes have a power range from 100W to 10 kW.
