Bezzera Duo MN Dual Boiler Espresso Machine – V2, Double PID
If temperature control and stability are what you're looking for, your search is over! The Bezzera Duo MN uses two separate PID's to control the temperature of the coffee boiler and the water/steam boiler. We caught a first-look of the DUO at HOST Milan 2017, and we were thoroughly impressed with the thought Bezerra has put into this beginner dual boiler espresso machine that will make distinct flavor profiles with ease.
The Bezzera Duo MN equips the DUO with a beautiful 3.5" LED touch display that allows the user to program a number of functions with ease. Adjusting the temperature between the two boilers is crystal clear, as well as checking the water levels. Other programmable features on the touchpad include:
- pre-infusion, priority heat up between boilers
- auto on/off settings
- switch between direct plumb and reservoir
- automatic backflush program
- maintenance reminders
- selection of language
Independently Controlled Boilers
Two separate PID's control the .45 L coffee boiler and 1L water/steam boiler. You can even program through the touch display which boiler you'd prefer to heat up first!
E61 Grouphead
The E61 grouphead ensures consistent water stability. Hot water circulates from the boiler through the grouphead and back to keep the grouphead and your portafilter nice and hot. Lever next to the grouphead activates a microswitch which turns on the pump to draw water through the coffee grinds.
Multi-Directional Steam and Hot Water Wand
Allows for more flexibility. Joystick controls for steam and hot water wands give instant on/off operation as opposed to knobs that you must turn clockwise / counter-clockwise. Each has a rubber cover to prevent fingers from burning.
Wooden Elements
Less plastic is always a bonus in our eyes. The Matrix is designed with wooden handles on not only the portafilter but the joysticks and lever as well.
Three Way Solenoid Valve
Allows quick removal of portafilter after espresso extraction by relieving the pressure built up in the grouphead. The result is a dry puck of coffee you can easily knock out of the portafilter.
Rotary Vane Pump and Motor
Produces a quieter extraction vs a vibratory vane pump. Situated underneath tank/reservoir and adjustment can be made from underneath the espresso machine.
Very Large Water Tank
A 4 L water reservoir means fewer refills for higher volume use, low water levels are detected by an electronic sensor and are indicated on the touch display. Refilling occurs from the top of the machine by lifting up the lid on hinges.
Passive Cup Warmer
Able to hold up to six cappuccino cups and passively warm them to ensure the coffee remains hot.
Automatic Water Refill to Boiler
Automatic plus safety cutout to prevent machine damage.

- Since this is a new model, every Bezzera Matrix/Duo model gets inspected, bench tested, and calibrated with 'water only' prior to shipping. Upon arrival, please use the machine within 5 business days.
- Do not move or lift the machine from the top rails as damage may occur to the rails or body of the machine.
- The Bezzera Matrix DE comes from Bezzera on a mini pallet, which is why we will ship this machine out to you, the customer, on a pallet. Additionally, it is less likely that your machine will arrive damaged with this shipping method.
- 15 AMP plug and cable are designed to be used with 15 AMP in a continuous way and they admit pick of current until around 20 AMP. During our tests, we recorded 17,76 AMP (as maximum current) only in the 3:20 minutes of the warm-up time (when both boiler heat up together).
- During the coffee brewing the service boiler heating element is disabled and when the machine is not used, thanks to the PID controls, only current impulses are given to the heating elements.
- Note from Bezzera dated 03/25/2021
- 20 AMP plug will continue to be used on Matrix and Duo 110 Volt versions because the safety standards do not allow the use of an undersized plug compared with the power consumption reported in the machine data label.
- We will add advice into the machine box where we explain to the final user that it is possible to use the machine with a 15 Amp plug adapter only setting a boiler priority.
- We would like to inform you that, according to our tests, the major difference in the machine performance, setting or not the boiler priority, is in the warm-up period.
- We faced no big performance differences in the coffee thermostability and water/steam services, in the regular machine use, giving priority to a coffee or steam boiler.
