The Professional model was born
in 1976-1977, with the aim of having a machine capable of delivering a
greater number of coffee than the model Europiccola and then be able to
meet the needs of offices or small communities..
Compared to the model Europiccola has the following characteristic:
-
the boiler is increased and
can contain up to 1,6 liters of water
-
the gauge to control the
proper pressure
-
the
pressurestat that keeps constant pressure in the boiler
-
the thermofuse to protect the heating element
Has remained basically unchanged until
today.
