Designed using cutting edge-technologies, the LT-Series ORC power generation modules by Zuccato Energia are a compact and efficient solution for small-scale primary power generation. Available with electric power outputs ranging from 100 to 550 kWE, they use overheated water as a vector fluid and find their ideal field of application in association with biomass-fueled boilers, as well as for waste heat recovery from furnaces, ovens and industrial processes in general.
