(An Infinity Modular ORC Turbine)


Organic Rankine Cycle Power Turbines are used to harvest low temperature heat or waste heat and convert it to usable energy.  This energy can then turn a generator to create electricity through a rankine steam cycle.  The ORC system works by using a high-molecular mass fluid to absorb heat.  Nanoparticle additives in the working fluid allow it to flash to vapor at a lower temperature than that of water

Infinity Turbine markets a modular ORC turbine that can be used in geothermal, biomass, and industrial waste heat applications; all of which are low temperature heat processes.  The Infinity ORC Turbine contains a closed-cycle heat transfer system that uses a high molecular mass fluid with nanoparticle additives as described above.  These additives enhance the heat transfer capabilities in the system, allowing for better operating efficiency.  Additionally, these turbines are modular, making system expansions economically feasible.  The direct benefit of this technology is the enhancement of waste heat to energy conversion in industrial and utility scale applications.
