System to connect multiple ModvFresh DHW modules in cascade for installations requiring high power and flow rates, or with low-medium temperature heat sources (heat pumps).

ModvFresh Kascata is an innovative control logic that allows multiple standard ModvFresh pump units to be connected in cascade for the production of domestic hot water (DHW), enabling a maximum flow rate and thermal power exchange equal to the sum of the individual modules' performance.
The system is suitable for applications with large buffer tanks connected to solar thermal circuits, heat pumps, biomass boilers, etc., ensuring the production of instantaneous domestic hot water while preventing legionella growth due to stagnation of heated water.
The entire system is managed via a bus connection that links the control units of the individual ModvFresh units. By monitoring the flow rate from the hot water system, the control units activate the necessary DHW modules, controlling the respective actuators on the cold water inlets. This Kascata system proves to be highly flexible and can be designed and built with a modular approach to meet the specific needs of the system.
The control logic thus optimizes operation when combined with low-medium temperature heat sources, such as heat pumps.

ModvFresh cascade connections maximize efficiency by fully utilizing the thermal energy available in the buffer tank. The configuration can be adapted to the project requirements, which typically vary between installations in terms of temperature, storage volume, flow rates, and the required temperature for use.
