SINCE 1980
Turboden is an Italian firm and a global leader in the
design, manufacture, and maintenance of Organic
Rankine Cycle (ORC) systems, highly suitable for
distributed generation.
ORC systems can generate electric and thermal
power exploiting multiple sources, such as
renewables (biomass, geothermal energy, solar
energy), traditional fuels, and waste heat from
industrial processes, waste incinerators, engines or
gas turbines.

ADVANTAGES OF GEOTHERMAL BINARY PLANTS
FOR HIGH ENTHALPY
 Capable to exploit both the separated hot brine & steam (two phase flow)
 Higher efficiency (steam consumption < 7 tph/MW) than single flash plants (for small units < 10 MW)
 Lower CAPEX than single flash plants (for small units < 10 MW)
 Early generation, relocation option, no complicate steam gathering system
 Full reinjection of geothermal fluid is possible (with dry cooling)!
 Low requirement for land (wellpad generation with simplified gathering system)
 Stable base-load energy and island mode operation
 Proven and mature technology
 Scalable to utility size (modular technology)
