The system finds application with buffer tanks of large plants connected to solar thermal circuits, biomass boilers (e.g. pellets and wood), etc, and guarantees the production of instantaneous domestic hot water avoiding bacterial contamination phenomena (such as Legionella) due to stagnation of heated water.

The entire system is managed thanks to a bus connection that connects the control units of the individual Modvfresh 4 units. The control units by reading the flow rate coming from the hot water system, consequently activate the necessary DHW modules, by controlling the respective actuators on the cold water inlets. The Kascata system thus proves to be truly flexible and can be designed and buit with a modular approach, according to the specific needs of the system.

 

The control logic also allows you to optimize the operation in combination with medium-temperature heat sources, such as for example heat pumps (HP). By connecting in cascade the ModvFresh modules it is possible to maximize the efficiency, making the most of the thermal energy available in the buffer tank. It is possible to adapt the configuration to the project data, which generally are different from one plant to another for temperature and storage volume, flow rates and required temperature in use.
