Corvina Due — 2 Group
Tax included where applicable. Delivery and installation arranged by your concierge.
NAVERQIO Machines — nine bars, held steady
The Corvina Due is the working heart of a café: two saturated groups with independent temperatures, steam that never runs out of argument, and volumetrics that keep the queue moving without flattening the coffee.
The shell is brushed AISI 304 stainless over a welded steel chassis; boilers are marine-grade copper or 316L stainless, insulated so the element works less and the room stays cooler. Groups are machined from solid brass, chrome-finished where lips and spouts touch, and every joint is TIG-welded by hand and pressure-tested twice before the panels go on.
Design & Craft
- Boilers in copper or 316L stainless, insulated and TIG-welded by hand
- Independent group temperatures for a multi-coffee menu
- Bench-tested in Prague on your water profile before dispatch
- PID-held brew temperature, stable to a fraction of a degree shot after shot
- Panels remove with one tool — built to be serviced, not replaced
- Two years parts and labour; parts stocked for fifteen

Questions, Answered
Does it run on Czech household power?
Single-group and home machines run on standard 230 V / 16 A. Two- and three-group commercial machines may require a dedicated circuit or 400 V supply — the exact requirement is in the specification, and our crew confirms it before delivery.
How fast is service if something fails?
Prague and Brno: typically next business day on site. Elsewhere in CZ/EU: advance-exchange parts by courier with a technician on video, or an on-site visit scheduled within the week.
The NAVERQIO Promise
