Coban Lever Machine — Due
Tax included where applicable. Delivery and installation arranged by your concierge.
NAVERQIO Machines — nine bars, held steady
Lever machines survive because nothing about them is fashion. The Coban carries the tradition properly — machined brass, honest gauges, silence between shots — and adds the boiler control the classics never had.
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
- PID-held brew temperature, stable to a fraction of a degree shot after shot
- Pre-infusion by geometry, not gadgetry — the lever is the profile
- Silent between shots: no pump, just spring, steam and patience
- Bench-tested in Prague on your water profile before dispatch
- Sight-glass boiler with honest brass gauges you can read across the bar
- Boilers in copper or 316L stainless, insulated and TIG-welded by hand

Questions, Answered
Tank or plumbed?
Machines listed as plumbable ship with both options where the platform allows; our installation includes connection to treated water and a drain if they are within reach of the bench.
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.
