Nuova Simonelli Wave II – 2-Group Digital Espresso Machine

Professional-grade espresso performance, built for busy cafés.
The Nuova Simonelli Wave II brings commercial-level power, precision, and workflow efficiency into a compact 2-group footprint. Whether you’re running a high-volume café, a specialty roaster’s espresso bar, or a boutique shop, Wave II delivers consistent temperature stability, reliable steam, and programmable control — ensuring every shot meets your standards even during peak hours.

Built for baristas, designed for consistency and flexibility.
With a full digital touch interface, Wave II lets you program shot volumes, adjust boiler pressure and pre-infusion settings, and manage energy-saving modes for off-hours. The built-in volumetric dosing, combined with the machine’s soft-infusion system, produces consistent extraction with less reliance on perfect tamping — ideal for cafés serving many shots per hour. Two cool-touch steam wands and a hot-water outlet allow efficient preparation of milk drinks, americanos, or teas. Raised group heads give enough clearance for tall cups, and ergonomic design features help baristas work efficiently all day.
