Ijen Lever — Bar Edition
Tax included where applicable. Delivery and installation arranged by your concierge.
NAVERQIO Machines — nine bars, held steady
The Ijen is espresso at walking pace: a spring lever that draws its own pressure curve, a boiler you can hear think, and shots with the soft sweetness only levers pour. No pump, no hurry, no apology.
We build espresso machines the way boiler-makers used to: thick copper and stainless, brass groups machined in-house, silicone-free food-grade seals, and wiring looms labelled so a technician in ten years thanks us by name. Panels come off with a single tool; nothing structural is glued; every fastener is stainless and standard.
Design & Craft
- Spring-lever group delivers a natural pressure curve from 9 bar down
- Pre-infusion by geometry, not gadgetry — the lever is the profile
- Boilers in copper or 316L stainless, insulated and TIG-welded by hand
- Sight-glass boiler with honest brass gauges you can read across the bar
- Solid brass groups machined in-house and pressure-tested twice
- Bench-tested in Prague on your water profile before dispatch

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.
Is training included?
Every machine handover includes a commissioning session; espresso machines add a barista induction on your own equipment — dialling in, milk, cleaning and the daily routine.
