MACS® TECHNICAL DATA CHART
The curves in below charts are useful to calculate the flow rate of DHW product by a
MACS® module unit depending on the DHW desired temperature( value reported on
the horizontal axis)
The various curves are determined according to 3 parameters: the temperature of the
storage tank; the temperature of the heating water flow returning to the storage
tank and the inlet temperature of the DHW water.
