Fresh water station FRIWA 50 HE

Hygienically DHW preparation ...

High Efficient fresh water stations FRIWA 50 HE are available with plate heat exchanger either copper welded or full stainless steel. Upon request of the flow sensor hot water is pumped from the buffer tank through the heat exchanger. On the reverse-flow-through principle the hot water hygienically is heated up only as much as required. A constant hot water temperature is guraranteed via electronic control of the loading pump. A calcination protection is given by the intelligent design and construction of the different components. An integrated dirt trap valve on the cold water side protects the heat exchanger against impurity. Stop and flush valves assure a high level of usability and an easy maintenance. Special wall brackets are integrated for a quick and simple wall fastening. FRIWA 40 HE is completely premonuted the station has just to be connected with the buffer tank and the drinking water circuit.
