CHP-Series ORC Modules
Combined heat and power generation


The CHP-Series Organic Rankine Cycle modules by Zuccato Energia are highly versatile combined heat & power generation systems capable of producing 80°C hot water as well as electricity. This makes them ideal in all those situations where a hot water source is needed and makes them eligible for state incentives for cogeneration plants. Furthermore, the ZE-175-CHP twin model also has the exclusive capability to be quickly switched from CHP mode to full-power mode whenever hot water is not needed, achieving even higher efficiency and electrical power output and offering maximum versatility to the user.
