Designed using the most advanced technologies, the ULH-Series ORC power generation 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, 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
