Here, a steady low pressure pre-infusion gently expands the grinds before stepping up to high pressure for an even extraction. Die cast, semi-automatic machine. Programmable shot volume. Electronic pid temperature control for increased temperature stability. 1600W thermocoil heating system to accurately control water temperature, espresso pressure gauge and bpa free materials.
