The Duetto IV Pro 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. With the Duetto IV you’ll be set to produce approximately 20 beverages per hour. 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.
