The value of water can often not be expressed in price, especially in regions where water is a scarce asset. Learn more about Heat ReCycle in our webinar.

An ORC array uses an organic fluid characterized by high molecular mass (e.g., silicon fluids, hydrocarbons, or refrigerants) and a lower boiling point than water as a heat-transfer medium. This is evaporated in a boiler to convert industrial exhaust heat into mechanical energy and then electricity before passing through a heat exchanger for recondensation.

Because it operates at comparatively low temperatures, an ORC is especially effective for heat recovery in combination with gas-powered turbines, as well as concentrated solar power, biomass, or geothermal plants. Unlike a conventional combined cycle power plant, this hermetically sealed cycle does not require water, making it a good choice for arid locations.
