Decent Espresso DE1PRO

The DE1PRO is the heavy-use version of the Decent DE1 platform: the same software architecture as the rest of the range, but internal components rated for continuous duty, backed by a 200,000-shot warranty versus the base DE1+'s 10,000. The dimensions on the official comparison are 23.2 x 36.9 x 42 cm (W x D x H) for 13.2 kg, with peak draw up to 1500 W on the steam element. The manufacturer states two mains-voltage versions, 110 V and 220 V, with peak draw of 15.9 A and 8.2 A respectively.

The DE1PRO's core feature is flow control: you draw the desired flow curve with a finger during extraction and the machine automatically adjusts pressure to hold it, while sensors detect when the puck is saturated to trigger the main shot. Pressure can go up to 13 bar for anyone experimenting with finer-than-usual grinds. The tank holds 2 liters, good for about 20 espressos per the manufacturer, and the machine can run stand-alone or plumbed in.

Full warm-up, with steam ready, is stated at 270 seconds (135 if only coffee is needed). The manufacturer does not specify pump type, portafilter diameter, or group type: figures anyone evaluating the DE1PRO will need to look up elsewhere.
