Company History


In 2006, Calnetix acquired Turbogenix, a small start-up company specializing in heat recovery equipment and created Calnetix Power Solutions (CPS), a wholly owned subsidiary of Calnetix, Inc. based in Stuart, Florida.

Utilizing Calnetix’s existing technologies and design support, a state-of-the-art Organic Rankine Cycle (ORC) system was developed for the purpose of recovering heat from internal combustion engines and biomass boilers.


After working with General Electric’s Energy Division on multiple contract projects, the CPS system was recognized by GE Energy as “best in class.” Through an exclusive license of the ORC system for land-based power generating engines and turbines, CPS was purchased by General Electric’s Energy division in October of 2010.


In January of 2011, Calnetix installed its first ORC system on an active, producing oil and gas well, recovering the heat from coproduced brine. This installation served as the basis for the formation of Access Energy.


In May of 2014, Daiichi Jitsugyo acquired the manufacturing and marketing rights to the Thermapower® ORC product line in Japan.


In April of 2016, Daesung High-Tech became a distributor of Thermapower® products in South Korea.

In August of 2016, Tokyo Boeki acquired exclusive manufacturing rights to the Hydrocurrent® ORC shipboard heat recovery system for engine jacket water. The product is sold and supported by Mitsubishi Heavy Industries Marine Machinery and Engine Company (MHI-MME) through its worldwide distribution channels.

Since the first Calnetix 125kW production unit was installed at a beta site in Lakeland, Florida in June of 2009, the 125kW ORC system has been operational in various applications in the United States, Canada, Europe, the Middle East and Asia. Over 56 MW of capacity has been installed worldwide.


Our Facility

Access Energy’s headquarters, engineering and manufacturing facility is co-located with parent company Calnetix Technologies in a 66,500 square foot building on over seven acres in Cerritos, California.

Access Energy has a state-of-the-art test facility for its Organic Rankine Cycle (ORC) heat recovery systems. The test equipment can generate heat from 185° F (85°C) to 400° F (204°C) in liquid and vapor form and can handle the testing of up to three ORC units simultaneously regardless of the temperature required for each unit.
