A low-enthalpy, high-efficiency LT-ORC module that's ideal for waste heat recovery from low temperature thermal sources (e.g. engine cooling jackets, flue gases, geothermal heat)
A Rankine-cycle power production module ideal for primary power production in small/medium sized plants when combined with any type of boiler
Our Low Temperature Organic Rankine Cycle power generation modules are all mounted in self-contained skids ready to be integrated in your system by simply connecting them to the thermal loop (hot or overheated water depending on the model).

Location: Arzene (Pordenone, Italy)
Plant: 1 x ZE-150-LT power generation module
Application: Primary energy production in connection with a boiler fueled by chicken dung
The Biagi Alfio farm, located in Borgoforte, near Mantua, Lombardy, Italy is a livestock farm specializing in pigs, which has decided to acquire a biogas production system fueled by the fermentatio of the sewage created by its 10,000-odd pigs.
The biogas produced in the fermenting tanks is used as fuel for a micro power plant based on a 637-kW engine by the german firm Jenbacher. Said plant takes advantage of the favorable all-comprehensive tariff the Italian government grants to new small power plants powered by renewable energy sources.
The system Zuccato Energia supplied is a ZE-50-ULH low temperature organic Rankine-cycle module which recovers waste heat from the flue gases and cooling jackets of the forementioned Jenbacher engine, thus contributing significantly to the overall system efficiency and productivity.
The LT-ORC module is entirely contained in a custom container, located outdoors, which is both compact (4,2 x 1,5 x h 3,1m) and totally weatherproof. This container hosts the whole ORC system, including turbine, secondary heat excangers and control panel, as well as a climatization system for the control panels. Cooling for the condensation part of the cycle is ensured by an EvapCo cooling tower located beside the container.
The fuel used by the Jenbacher engine (biogas) is an environment-friendly, renewable energy source made competitive by state and regional incentives. It is also CO2-neutral, as burning biogas releases in the atmosphere the same quantity of CO2 which was once captured by the plants that went to feed the animals.
