Optimum precision, thermal stability, dual boiler technology Cinquantotto translates to 58, the new R 58 from Rocket Espresso. Dual independently operated PID controlled boilers allow for optimum extraction of any coffee type or roast style. Rocket Espresso inclined boiler technology means precise group temperature adjustment and unprecedented levels of temperature stability. Commercial grade rotary pump draws from the machine's internal water reservoir or allows for a direct water connection from the water supply. Machine functions are controlled by the touch screen communication pod that now includes an automatic on/off function – your machine is ready to go whenever you need coffee. The communication pod can easily be removed from the machine to retain the aesthetic that is Rocket Espresso.
