Solar thermal collectors


Integrated exchanger

Solar domestic hot water

High efficiency circulator pump

The solar charging station DN15 with integrated exchanger ensures optimal transfer of solar heat energy towards the hot water storage tanks.
The presence of high efficiency circulators and of the controller 600i allows a perfect adaptation of flows in response to fluctuations in solar radiation, temperatures in the storage tanks and different requirements requested.
