5.6 Additional notes for models NeW 105 DTC (Dual Temperature Control)
The cooling system of the models NeW 105 DTC has the purpose of ensuring thermal stability of the water used
for serving espresso coffee. This system uses a special serving group in which the cold water from the mains
passes through a small tube located in a compensation chamber. The hot water from the heat exchanger of the
boiler passes through the serving group and comes into contact with the cooling tube. As a result it loses heat.
