Data from official source
Bezzera Duo, in the DE version described here, is a dual-boiler machine: a 0.45-litre coffee boiler and a 1-litre service boiler, each with its own PID thermostat, for a stated total of 3 PIDs. The manufacturer describes it as a compact semi-professional machine with the production capacity of a professional unit, with stated dimensions of 326x470x425 mm and a weight of 31 kg.
The hydraulic system is powered by a rotary pump that can draw from a 4-litre internal tank or be connected directly to the water mains, as stated for both versions of the model. Pre-infusion is settable, and the DE version dispenses coffee volumetrically via microprocessor with 4 keypad-programmable doses plus a button for continuous dispensing.
The manufacturer does not specify the brew group type (E61 or proprietary), the boiler material, the operating pressure in bar, the heat-up time, the presence of a pressure gauge or a 3-way valve, the steam wand type, or the portafilter diameter.
