We introduced Izzo to the North American consumer decades ago and they still impress us daily! Unwavering focus on quality from the stainless steel frame, gorgeous industrial stainless steel body, down to the bits that you won’t see - like the stainless steel mushroom and gicleur. The Alex Duetto not only stands out on the counter of your kitchen, but you’ll be just as impressed as we are daily with the build quality for decades to come.
A reduction in the size of the drip tray has increased cup clearance, a common request, which leaves plenty of room - nearly six inches of cup clearance even your favorite mug will fit under the group! Not only is the Alex Duetto an impeccably made dual-boiler home espresso machine, but it has an incredibly flexible feature set as well.
Operating any espresso machine within your home or a commercial setting noise is always a concern. To reduce the sonority of the Alex Detto we have updated the motor mounts to reduce vibration while activated. The pump and motor are where a majority of your machine’s noise will stem from; in addition to the new motor mounts, an even quieter rotary pump has been installed. There is now also a solid-state relay (SSR) which is more reliable and quiet. The drip tray is equipped with two small magnets that reduce vibrations within the drip tray.
What is preinfusion? Pre-Infusion is the act of introducing water to your puck of coffee inside your insert basket at a lower pressure, usually 1-4 bars, prior to full pressure. On an E61 group, mechanical pre-infusion utilizing the three-way valve uses residual pressing either within your brew boiler or if plumbed, your water source’s line pressure. The residual pressure is used to introduce pre-infusion when your cam lever (brew lever) is in the first position. The benefit of preinfusion is that it settles the coffee within your portafilter’s insert basket reducing channeling and decreasing the likelihood of under extracting.
Switching water sources is made incredibly simple with the single toggle switch located behind the magnetic drip tray. Easily switch water sources from the nearly three-liter reservoir to direct-plumb. The Alex Duetto also has the ability to easily switch between the most common configuration for the home kitchen, 15-amps, or ‘full-power’ mode with 20-amps. Quickly switch between the two with a couple of clicks of your built-in PID controller.
Each boiler on the Alex Duetto is independently controlled and operated. If you’re not using the service boiler, this is where your steam and hot water comes from, you can turn that boiler off while leaving your brew boiler on. This switch is located on the right side of the most recent model of the machine near the illuminated power switch.
With five distinct configurations available for the Izzo Alex Duetto IV Plus we at Chris' Coffee, want to offer "best in class" machines, ones that you'll have for many years to come! The ability to customize our curated selection of home espresso machines is imperative to make it your own. Like many of our espresso machines - joysticks can easily be added during bench testing at no additional charge. If you do select that you’d like the default non-compression steam knobs you can select between 4 unique colors: black, red, white, and wood. When selecting red, white, or wood you’ll get the following in addition to the already included accessories:
- 1 Single and 1 Double Spout Portafilter with insert baskets
- 1 Matching Tamper
- 1 Brew Lever Knob in the color of your choice
- 1 Steam Knob and 1 Hot Water Knob in the color of your choice
- All original knobs and portafilters included with the machine are also included!
- All labor included! We'll install your kit while we bench test!
The tried and true construction of the Alex Duetto has been brought to their latest model, the Alex Duetto IV Plus. T.E.A Coated insulated copper boilers ensure maximum heat retention, much greater than stainless steel boilers, as well as a considerable reduction in the price! With a copper boiler, you’ll also have less susceptibility to chloride stress corrosions which could occur in other Alex Duetto models after having this lifelong companion for a couple of years.
Through our work with Izzo, some seemingly minor changes were made that increase longevity and decrease repair costs. We have inverted the motor position underneath the pump. This inversion ensures that if your pump was to fail it will not also destroy the motor by leaking into it. In addition to the inversion of the motor position, it is also easier to adjust pump pressure with the easy-to-access expansion valve. This adjustment is visible underneath the cup warming tray, which is easy to remove without even moving your cups, and adjusts your pump pressure with the turn of a screwdriver.
A common complaint we hear when people receive their machine with an E61 style machine is the flexing of the front panel over time. This is a common complaint that as you lock your portafilter into place, most particularly when you have a brand new gasket, well we’ve thought of this too! Izzo has reinforced the front panel to reduce flexing which further contributes to this substantial machine’s commercial build quality for your home.
Each boiler on the Alex Duetto IV+ is PID controlled to the degree in either Fahrenheit or Celsius which is easily changed right on the controller itself. Also integrated within the PID is a shot timer.
With almost all of our home espresso machines, they carry a two-year warranty provided directly through us, Chris’ Coffee. This two-year warranty provides nearly everything that you’d need to fix flaws that may arise during this time period. After that time, however, you are not left out in the cold! Our service technicians are always available by phone for you. Knowing that many of you will have to make some repairs yourself we have made the following adjustments to the Alex Duetto IV+ to make your life much easier while self-repairing.
- 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.
