The Giotto Evoluzione machine is equipped with a copper and insulated boiler for energy saving and increased thermal stability.
Stainless steel frame AISI 304 and stainless steel cupsframe.
Twin manometers to check both pump and boiler pressure to control the correct brewing extraction process, full Commercial rotary pump and the option of direct water connection or water tank supply, the mechanical grade pressustat complete the technical advanced main characteristics of this model.
BREWING PRESSURE PROFILING CONTROL
The pressure gauge set on the group, allows to read the brewing pressure profiling of the espresso. Thanks to this instruction the barman can verify the exact milling, pressing and dose of the coffee in the filter.
If the brewing pressure is lower than the pump calibration (9 bar is our company setting), it means that the grinding is coarse, or the coffee is not pressed correctly, or the dose is not enough.
