Izzo Alex Duetto IV Plus 1 Group Espresso Machine (White/Wood knobs)
Category: Dual Boiler
Izzo Alex Duetto IV Plus
Two boilers. Zero compromises. Set your brew temp and steam temp independently.
The Duetto IV Plus runs a true dual boiler system — one dedicated to brewing, one dedicated to steam. You control each temperature independently for total precision over extraction and milk texture. PID regulation on both boilers means the heat stability doesn't drift, whether you're pulling your first shot or your tenth.
How It Works
Unlike heat exchanger machines that share a single boiler for both tasks, the Duetto IV Plus separates brew water and steam into independent systems. Your brew boiler holds the exact temperature your coffee needs — light roasts at higher temps, dark roasts lower — while the steam boiler maintains its own pressure for immediate, powerful steaming. PID controllers on both boilers make continuous micro-adjustments, so your temperature holds steady through back-to-back shots without any recovery lag.
The Engineering
Dual Boiler System
Separate boilers for brew and steam mean you never wait for temperature recovery. Pull a shot and steam milk simultaneously with full independent control.
PID on Both Boilers
Precision PID regulation on each boiler ensures consistent heat stability from the first drink to the last. Your extraction temperature stays where you set it.
Professional Components
Built with commercial-grade internals that hold up under daily use. Reliable performance whether you're serving your household or a small cafe.
Simultaneous Operation
Brew and steam at the same time with no temperature interference between the two. Your workflow moves as fast as you do.
White / Wood Knobs
Clean white exterior paired with natural wood knobs. Warm, refined, and built to anchor any countertop setup.
Who It's For
Great Fit
Serious home baristas who want independent brew and steam temperature control. Small cafe owners who need dual boiler reliability for back-to-back milk drinks. Anyone upgrading from a heat exchanger and ready for real temperature precision.
Not The Best Fit
Casual espresso drinkers who mostly pull straight shots without steaming. Buyers on a tight budget — single boiler machines offer strong value under $2,000. High-volume multi-group commercial environments.
