The Duetto IV Plus

Innovative and professional, suitable for domestic use, named Duetto from its capacity to manage separately both steam and coffee delivery with a dual boiler system. This prosumer espresso machine is solidly built from stainless steel and is very aesthetically pleasing. 

It can work with a water tank or can be plumbed directly. It is equipped with an E61 group, pre-infusion, plumb-in or water reservoir options, a professional and noiseless rotary pump and a thermo regulation managed by a PID (added controlled temperature stability) which now features a shot timer.

The new Duetto IV Plus features a new tank design which allows for ease of access to the tanks and heating elements and now both tanks now have drain plugs. The new motor has been installed vertically over the pump thus eliminating the concern of the water leaking into the motor. It is now also possible to adjust the pump without dissembling the machine by way of a small cutout in the bottom side panel. The new upgrades all add up to an amazing new design of the Alex Duetto.

PID Controls

Some of the functions of the PID include:

• Controls the temperature in the group boiler AND the steam boiler. (No Pressure stat)
• Easily changes the machines operational mode from 15 amps to 20 amps.
• Temperature display easily changed from Fahrenheit to Celsius.
• Can program the offset settings for both boilers.
• Default values for P, I, and D can be changed (please consult with our Service Department prior to changing).
• Either boiler can be turned off. (save energy and turn the steam boiler off if you only want espresso)
• Note: You can also turn the steam boiler on and off with a switch on the side of the machine.

Because it is a double boiler espresso machine, the Duetto IV is a wonderful tool for both traditional espresso and milk based drinks and it is a quiet worker. Whether at home or in the office this sleek, conversation starter will quickly and quietly perform.
