Located in Naples Italy near the famous Mt. Vesuvius, Caffe Izzo manufactures exceptional espresso machines for the sophisticated espresso lover. Since 1979 Caffe Izzo has been improving and refining its designs offering customers the ability to create a true Neapolitan espresso experience in the home kitchen with Izzo espresso machines. Check out the Alex Duetto 3.0 at 1st in Coffee which features dual boilers and independent temperature adjustment by PID controller.
The PID, or proportional-integral-derivative controller, employed by Caffe Izzo for the Alex Duetto espresso machine is the best solution we’ve seen to eliminating human error in espresso making. The scientific explanation is that the PID operates on an algorithm which attempts to minimize error by adjusting the process through use of a manipulated variable. The easier explanation is that Izzo espresso machines automatically correct for very small errors that may occur in the brewing process such as exact temperature control, steep time, and pressure consistency. This allows the home and restaurant brewer to create consistently exceptional espresso with ease.
