Izzo Alex Duetto IV Plus Semi-Automatic Espresso Machine
Bridging the gap between consumer and commercial espresso machines has been the aim of Izzo’s Alex Duetto since the V1 was released several years ago. Features like a 2.6 liter combined boiler capacity, a built-in shot timer, an E61 grouphead, and PID temperature control raise the bar for home espresso machines and maintain the Duetto’s position as a quality standard for both home and light commercial use. Now in its fourth iteration, the Izzo Duetto IV Plus is better than ever. It combines classic features with new, convenient upgrades aimed to enhance both the user experience and serviceability. Most notably, the Duetto now includes a PID with an integrated shot timer, and an external adjustment for brew pump pressure. At heart, the Duetto IV Plus is a feature-filled commercial machine packed into a home machine’s body -- the espresso lover’s dream.
The Duetto IV Plus is small enough to fit into most kitchens, yet large enough to handle light order volume in a commercial setting. We often recommend the Duetto to small businesses or catering operations where coffee service is secondary. Utilize the Duetto’s 20 amp power option and you’ll be set to produce approximately 20 beverages per hour -- or about 1 every 3 minutes. A 32 oz drain tray and 2.4 liter water reservoir are sufficient for sustained use, but to avoid interruption the Duetto can also be direct plumbed (intake and drain) which negates the need to refill the reservoir and dump the drain tray. The Duetto also features a rotary/vane pump instead of a vibratory pump, which helps it run quietly. Rotary pumps reach full brew pressure almost immediately, and tend to be more dependable in the long run. Precision temperature control via the PID display on the front of the Duetto offers control in increments of 1 degree over both brew and steam temperatures. Customize your extraction and steam power to your desired parameters for commercial-quality results.
