Organic Rankine Cycle (ORC)

Concepts NREC Knows About Heat Recovery

Concepts NREC can design custom compact, high-speed, hermetically-sealed turbogenerators based on your-specific needs. These turbogenerators convert low temperature heat to electric power using an Organic Rankine Cycle (ORC) process.

Concepts NREC also offers design plans and the intellectual property needed to manufacture your own turbogenerator. To find out more about licensing options, please contact

These systems produce electric power by converting thermal energy to electrical energy. And, when site conditions involve temperatures too low for conventional heat recovery systems, ORC processes become the best solution. These are typically defined as any heat source at temperatures below 800oF. In fact, according to one U.S. Department of Energy report, there could be as much as 1.5 to 2.0 quadrillion BTU/year of heat with temperatures below 500oF available from exhaust gas streams in the industrial sector alone. Naturally occurring heat sources may be just as plentiful.

Concepts NREC has developed several ORC energy recovery machines for customers, similar to the one below. The design is a patent-pending, hermetically-sealed design, with an ORC turbine and permanent magnet generator directly coupled that improves mechanical efficiency by up to 10 percentage points over conventional designs.Cn300_Illustration.jpg


With its inherent flexibility, our design offers more power and revenue for a given heat source, greatly reduced operating and maintenance costs, increased reliability, and a significantly smaller footprint than any other ORC turbogenerator available in the world today. To consider anything else for low temperature waste heat recovery systems could be an expensive mistake.
