Ravenna Uno Alta — 1 Group
Tax included where applicable. Delivery and installation arranged by your concierge.
NAVERQIO Machines — nine bars, held steady
A single group done seriously beats two groups done cheaply. The Ravenna Uno carries commercial boilers, saturated temperature stability and certified paperwork — in a footprint a narrow bar forgives.
Thermal mass is the quiet ingredient. Oversized boilers, insulated lines and saturated or thermosyphon groups hold the brew path within a fraction of a degree, so the tenth shot of the morning tastes like the first. PID control reads twice a second; the needle on the gauge is there for the pleasure of it.
Design & Craft
- Boilers in copper or 316L stainless, insulated and TIG-welded by hand
- Solid brass groups machined in-house and pressure-tested twice
- Food-grade, silicone-free seals; every fastener stainless and standard
- Saturated or thermosyphon groups that shrug off the morning rush
- Two years parts and labour; parts stocked for fifteen
- Panels remove with one tool — built to be serviced, not replaced

Questions, Answered
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.
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.
The NAVERQIO Promise
Delivery is not a courier and a doorstep. Our crew carries it in, levels it, plumbs it where plumbing exists, commissions it, and stays for the first flight of shots.
