2 Environmentally friendly AQYLON s organic working fluids have a very low Global Warming Potential (320). Refrigerant fluids can be used but their GWP range between 800 to Rugged AQYLON s ORC modules are designed for durability and fit into standard containers, allowing for modular deployment. Efficient AQYLON s ORC modules apply cutting edge technology to maximize efficiency according to the heat source. AQYLON holds four patents related to turbines and ORC technology, and eight more are pending. Heat recovery from diesel engines and gas turbines ORC modules are available for solutions up to 10 MWe. AQYLON s ORC modules convert waste heat contained in exhaust fumes into electricity. Our Organic Rankine Cycle (ORC) technology increases electricity production from engines or gas turbines by around 10%. Because the heat to drive the ORC cycle comes from the exhaust fumes, fuel consumption is unaffected. When recovering exhaust fumes, a heat exchanger (boiler) must be placed on the chimney to collect the heat and transfer it to a thermal oil loop that will feed the ORC module. Aqylon can valorize flue gas. Gas turbines u The heat output of gas turbines can be recovered in the form of high pressure and high temperature steam. It is possible to significantly increase the electrical output of the assembly and improve the overall electrical efficiency by installing an ORC solution to use this steam. Recovery of the heat output in the form of high pressure and high temperature steam.

3 ORC technology avoids corrosion issues and turbine wear associated with steam turbines such as blade erosion and high speed operation resulting in low maintenance costs. Our ORC modules can rapidly ramp up to match changing power needs, from 60% up to 120% of nominal capacity. Rugged design ensures a life expectancy of over 25 years.

We also propose direct condensed solutions (when the coolers are directly condensing the working fluid) Reliable and decentralized energy The organic fluid is vaporized in the evaporator(1) and then supplied to the ORC turbine(2) that drives a generator(2), producing clean and reliable power. The vaporized fluid enters the regenerator(2) to give its remaining energy to the liquid organic fluid. The steam is then condensed in a condenser(2) which is supplied with cooling water. The condensed fluid is then pumped(3) into the regenerator(2) and finally into the evaporator(1) to close the circuit. AQYLON ORC modules are preassembled in our facility workshop near Paris in two 40ft containers for the 1MW unit.
