The Expobar Office Control has four programmable buttons and one manual button. This allows any user, independent of their skill level, to brew a volume-specific shot, to their taste, at the press of a button. Expobar's redesigned E61 group head incorporates a pre-infusion chamber above the shower screen, delivering even saturation of the coffee during the pre-infusion and through the pour for superior espresso shots.
The thermo-syphon system automatically circulates hot water through the group head while the machine is idle. Hot water flows from the heat exchanger into the group head through the upper pipe. As heat is transferred to the group head the water cools and leaves the group head through the lower pipe. The continuous movement of hot water maintains the group head at a stable temperature vital for producing a consistently great espresso.
Over Pressure Valve
An adjustable OPV (Overpressure valve) limits the group head pressure for optimal extraction.
The steam wand produces a powerful dry steam ideal for texturing milk. The ball joint connection allows perfect positioning of the steam wand. The commercial soft-close valve provides easy steam pressure control with minimal wear.
