From an idea of EXERGY CEO Claudio Spadacini, after years of research

and development EXERGY launch the

Radial Outflow Turbine into the marketplace.

At theforefront ofinnovation

EXERGY become part of the Maccaferri Industrial

Group. Backed by the strong economical and organizational support

of the Maccaferri Group EXERGY start a period of rapid expansion and success in the market.

In September Exergy start up in Verbania the

first high enthalpy 1 MW Radial Outflow Turbine.

EXERGY install the world’s first Radial

Outflow Turbine in a geothermal binary plant

in Tuscany. The project is developed for the

Bagnore III power plant in Mount Amiata (Italy)

for Enel Green Power and represents a giant leap

forward for green energy allowing utilisation of

the untapped potential of an existing geothermal

resource.

Pamukören 1 and Pamukören 2, EXERGY’s

first geothermal projects in Turkey, in Menderes

Basin area, become operational. This project

was commissioned by Çelikler Jeotermal and EXERGY participated in

a Consortium with other partner companies.

In June EXERGY move to a custom-built

facility near Malpensa gathering all engineering,

manufacturing and operational functions to allow the R&D and engineering team to

work side by side with the manufacturing

department.

EXERGY experience consistent growth and success in the Turkish

market, winning key contracts and becoming established as a market leader for binary power

plant equipment.

In July EXERGY open a Turkish subsidiary

company based in the city of Izmir in order to

start local manufacturing of the EXERGY Radial Outflow Turbine and

directly serve the Turkish market.

In June the Denizli Tosunlar geothermal

power plant, the world’s first equipped with a

2-pressure-level cycle on a radial outflow

single-disk turbine, becomes operational.

This plant, commissioned by the client Akça Enerji,

represents a unique technological milestone for EXERGY confirming

the company at the forefront of innovation.

EXERGY start up their first 12 MW and 25 MW large scale geothermal

plants.

EXERGY is a global leading company in the design, engineering, manufacturing and construction of Organic Rankine Cycle (ORC) power plants for power production from renewable energy sources including geothermal, biomass, solar and from exhaust heat recovered from industrial processes and power generation.

EXERGY’s ORC systems stand out in the market for uniquely utilizing the pioneering technology known as the Radial Outflow Turbine (ROT).

Conceived by EXERGY and launched in 2009 this cutting-edge innovation has quickly become a gamechanger in the market bringing a consistent growth and success to the company.

With two manufacturing facilities in Italy and in Turkey and more than 120 employees worldwide, including engineers, product managers, technology specialists, sales professionals, service and quality managers,

01/WHO WE AREEXERGY has a global outreach and can develop, deliver and operate ORC power plants tailored for specific needs in every part of the world.

EXERGY carries out every step of the design and manufacturing process internally. R&D is a key distinguishing feature of EXERGY’s approach to any new project. The company is always committed to innovation and to new applications of the ROT technology.

EXERGY has a current installed and under delivery power generation capacity of over 300 MW and a global annual turnover of approximately 100 million USD (2015 figure).

EXERGY is a subsidiary of SECI ENERGIA, a sub-holding of the Maccaferri Industrial Group. The Maccaferri Industrial Group is an Italian corporation active across a range of industrial sectors with an annual turnover of 1.3 billion USD, counting 57 production plants and more than 5,000 employees across the globe (2014 figures).

Organic Rankine Cycle technology is employed efficiently for power production from low to medium temperature heat sources in the range of 80 to 400 °C.

The working principle of an ORC is similar to the most widely used steam Rankine

Choosing an ORC system gives several advantages over steam technology:

cycle. The main difference is the use of organic substances as working fluid, such as hydrocarbons and refrigerants, instead of water or steam. The organic working fluid has a lower boiling point and a higher vapour pressure than water and is thus able to use low temperature heat sources to produce electricity in a more

efficient way.The fluid is chosen to best fit the heat source according to their differing thermodynamic properties, thus obtaining higher efficiencies. Moreover ORC can also be an ideal solution when the size of the application is too small for a steam power plant to be feasible.

02/THE TE cHN O lOGy

1 The heat exchanger recovers heat from the primary source transferring it to a heat transfer fluid (hTF) 2 The organic fluid warms up in the preheater and vaporizes in the evaporator, extracting heat from the hTF, which returns to the heat exchanger 3 The vapour expands in the turbine, which produces electricity through the generator 4 Recuperator recovers the high-temperature heat still available in the vapor at turbine outlet transferring it to the organic liquid before the preheater 5 The condenser extracts the low temperature heat and turns the vapor back into liquid state 6 The pump increases the fluid pressure sending it to the recuperator, thus closing the cycle.

Designed by EXERGY, the Radial Outflow Turbine is a technology unique to EXERGY ORC power plants. EXERGY CEO Claudio Spadacini first conceptualized the idea of the ROT and launched it in the market and thus making a world first in the ORC industry.

The pertinent technologies are covered by multiple IP rights and EXERGY continues to work on further advances and new applications of its technology.

The key feature of the Radial Outflow Turbine configuration is the capability to convert the energy contained in the organic fluid into mechanical power with higher efficiency than the competing technologies on the market such as the axial or radial inflow turbine.

EXERGY ORC power plants utilizing the Radial Outflow Turbine as expander give some additional advantages over the common benefits given by a traditional ORC solution:
