50ULH-splash 800x399 IT

 

Designed using the most advanced technologies, the ULH-Series energy production modules by Zuccato Energia are a compact, high-performance solution to exploit low temperature heat sources. Available in a range of power outputs from 30 a 50 kWE, and capable of operating under partial load as well (i.e. with a lower than nominal thermal input), they find their optimal application in fields such as  heat recovery from engines, gasifiers and other industrial processes, as well as a primary power generation system in the exploitation of geothermal heat and concentration-type thermal solar systems.
