The Cascada Fresh Water Vertical Buffer Tank (Counter Flow) is the new compact solution for FRESH WATER production (In-line water heating) and heating.
It can be thermally supplied by many heat sources such as Solar Field, Heat Pump, Boiler and Heating Element.
System operation can be fully automated via PLC with real-time display provided via touch screen or computer.
