Highlights

New PID & badge as of October 2022!

Izzo has been a trusted brand among North American consumers for decades, and their quality has consistently impressed us. The stainless steel frame, industrial stainless steel body, and hidden components like the stainless steel mushroom and gicleur are all top-notch. The Alex Duetto stands out on any kitchen counter and will continue to impress for decades to come, thanks to its enduring build quality.

Why Buy?

The Duetto IV Plus Espresso Machine is expertly designed with dual boilers and heavy duty heating elements to ensure quick recovery time and the ability to make multiple café style drinks in a row with ease. Its sleek appearance is matched by its unparalleled reliability and functionality. Equipped with a dual PID with a built-in shot timer, this machine provides extreme temperature stability for efficient and consistent shots. The PID accurately monitors water temperature and ensures that it stays within a narrow range, unlike traditional thermostats which can cause temperature fluctuations. The Duetto also features lead-free copper and brass boilers, known for their superior heat retention compared to stainless steel. This means you can enjoy this machine for many years without worrying about chloride stress corrosion. With a raised E61 group head, it's easy to fit larger cups for to-go drinks or when you're running late. The 8-pound chrome plated brass group head also helps maintain water temperature for perfect shots with minimal heat loss.

 

Size

The reduction of the drip tray's size has maximized cup clearance by nearly six inches, fulfilling a common customer request. This allows even your favorite mug to fit under the group. Along with its impeccable construction, the Izzo Alex Duetto IV Plus espresso machine boasts a highly versatile range of features.

Noise

When using an espresso machine in your home or a commercial setting, noise is often a concern. To reduce the sound levels of the Alex Duetto, we have upgraded the motor mounts to minimize vibrations while in use. The main sources of noise in the machine are the pump and motor, but with the addition of a quieter rotary pump and a solid-state relay (SSR), the noise level is significantly reduced. Furthermore, two small magnets in the drip tray help to further reduce vibrations.

Pre-Infusion

Pre-infusion involves introducing water to the puck of coffee in your portafilter at a lower pressure (usually 1-4 bars) before full pressure is applied. This can be achieved through automatic pre-infusion using residual pressure from either your brew boiler or water source's line pressure on an E61 group. Benefits of pre-infusion include reducing channeling and improving extraction by settling the coffee grounds within the portafilter's insert basket.

Water Source

The Alex Duetto IV Plus Espresso Machine features a single toggle switch located behind the magnetic drip tray, making it effortless to switch between water sources. Easily transition from the three-liter reservoir to direct-plumb for added convenience. Additionally, the machine offers the flexibility to swiftly switch between the standard 15-amp mode for home kitchens, or the 20-amp 'full-power' mode. Simply use the built-in PID controller to toggle between the two options.

Boilers

Each boiler on the Izzo Alex Duetto IV Plus Espresso Machine has its own independent control system. When the service boiler is not in use, the steam and hot water are provided by the other boiler. You can turn off the service boiler while keeping the brew boiler on. The switch for this is located on the right side of the newest model, next to the illuminated power switch.

Internal Improvements

The Izzo Alex Duetto IV Plus Espresso Machine has undergone slight yet significant changes that improve its durability and reduce repair expenses. The motor has been relocated above the pump, preventing any potential damage in case of a pump failure. Additionally, the machine features an easily accessible pump adjustment screw on the left side for simple pressure adjustments using a screwdriver.

Reinforced Group

A common issue often reported when customers receive an E61-style machine is that the front panel tends to flex over time. This is especially noticeable when locking in the portafilter, especially if a new gasket is being used. However, this problem has been addressed by Izzo with the reinforced front panel, increasing the overall build quality of this commercial-grade espresso machine for home use.

15 Amp vs. 20 Amp

The Duetto IV has the capability to operate at either 15 or 20 amps. When making your selection, you can choose either option and we will configure the machine accordingly during the bench testing phase. Moreover, if you opt for 15 amps, we will provide you with a complimentary convertor cord. If you have any uncertainties or need further details, feel free to chat with us live in the bottom right corner of the screen.

Easy Repairs

• Boiler drain plugs make it incredibly convenient for you to drain your boilers for either shipping your machine during cooler weather or in preparation for descaling.
• Changing the heating elements on your Alex Duetto IV+ is now incredibly easy, two screws and you have full access.
• Heating elements and boilers anchored to prevent shifting, also rubber insulating boots cover key connections (similar to spark plug wires) for protection.
