Nurri is an artisan espresso machine manufacturer based in Naples, Italy, founded by visionary espresso engineer Antonio Nurri. Drawing on decades of Italian industrial design and technical innovation, Nurri bridges traditional Neapolitan lever extraction with modern, high-precision electronic temperature architecture and bespoke materials.

1st-line Equipment is the official direct U.S. importer, master distributor, and authorized warranty service center for Nurri. Working directly with Antonio Nurri and his Neapolitan workshop, 1st-line imports factory-configured 110–120V US-spec builds, subjects every machine to multi-point bench testing in New Jersey, and maintains an extensive domestic inventory of genuine OEM replacement parts, custom body panels, and wood accessories.

The Nurri Leva L-Type (L-Type SA / Leva) is widely regarded as one of the most innovative spring lever machines ever engineered. Traditional lever designs often suffer from thermal drift and lack extraction flexibility; the L-Type solves these historic limitations through several breakthrough technologies:

• Triple PID Temperature Regulation: Independently monitors and regulates the dedicated 0.8L stainless steel brew boiler, the 1.8L steam boiler, and an actively heated grouphead collar fitted with internal cartridge heating elements. This eliminates the temperature drops common in passive lever groups and removes the need for warm-up flushes.
• Commercial 54mm Spring Lever Group: Features dual heavy-duty internal springs delivering an authentic declining pressure profile—peaking around 9–11 bars of mechanical pressure and gently tapering down to 5–6 bars as the puck degrades, yielding exceptional sweetness, clarity, and thick, velvety crema.
• Rotary Pump Pre-Infusion: Uses a commercial rotary vane pump to deliver pressurized, adjustable pre-infusion (typically 2–3 bars) into the group chamber before the lever is engaged, ensuring complete, channeling-free puck saturation.
• Dual Boiler Steam Capacity: A dedicated 1.8-liter steam boiler provides commercial, dry steam velocity for rapid microfoam milk texturing without affecting brew temperature stability.

One of the most praised innovations on the Nurri L-Type is its grouphead pressure-release dump valve, controlled via a dedicated front paddle:

• Instant Shot Termination: On conventional spring lever machines, once the lever is released, the barista must let the full spring stroke complete into a catch cup or wait for pressure to dissipate before removing the portafilter (risking the dreaded "lever sneeze" or an over-extracted, watery shot). The Nurri dump paddle releases pressure immediately at your exact target brew weight, terminating flow to the cup instantly.
• Effortless Group Flushing: It allows you to quickly purge clean boiler water through the grouphead between shots without pulling the heavy mechanical lever down every time.

Your choice depends on whether you prefer the tactile experience of manual lever extraction or the streamlined workflow of a semi-automatic E61 platform:

• Nurri Leva L-Type: Engineered for the espresso purist and specialty coffee connoisseur who values the artisanal tactile ritual, declining pressure curves, and nuanced flavor separation unique to spring lever mechanics.
• Nurri R-Type DB (Dual Boiler): Built with dual PID-controlled boilers and a classic commercial E61 grouphead driven by a commercial rotary pump. Ideal for baristas who want consistent, programmable semi-automatic brewing, rapid workflow, and independent digital temperature control for both coffee and milk drinks.
• Nurri R-Type SB / HX (Heat Exchanger): A compact prosumer Heat Exchanger machine featuring an E61 group, a high-capacity 1.8-liter boiler (1200W heating element), and customizable magnetic side panels. It offers simultaneous brewing and steaming with commercial steam velocity in a space-conscious footprint.

Nurri machines are engineered with versatile dual-source water supply flexibility:

• Internal Water Reservoir: High-capacity internal water tanks fitted with electronic low-water magnetic sensors that alert the barista and automatically disable heating elements to prevent boiler dry fire when water levels run low.
• Direct Water Line Plumbing: Models equipped with commercial rotary vane pumps (the L-Type Leva and R-Type DB) feature direct plumbing kits. This allows you to connect directly to a cold water filtration line for uninterrupted brewing, passive line-pressure pre-infusion, and continuous drainage via a plumbed drip tray.

Proper maintenance protects Nurri’s internal boilers, precision cartridge heaters, and hand-finished bodywork:

• Water Chemistry (35–85 ppm Total Hardness): Always supply your Nurri with softened, filtered water (90–150 ppm TDS, neutral pH 6.8–7.4, 0 ppm chlorine/chloramines). Mineral limescale is the primary cause of hydraulic restrictions and heating element burnout, which voids manufacturer warranty coverage.
• Grouphead Hygiene: Clean the shower screen and dispersion block with a brush after every brewing session. On the R-Type semi-automatic models with 3-way solenoid relief valves, perform weekly chemical backflushing with an approved espresso detergent (such as Urnex Cafiza or Puly Caff).
• Lever Group Seal Lubrication (L-Type): Periodically apply a thin coating of high-temperature, food-grade silicone grease (like Dow 111 / Molykote 111) to the 54mm piston seals and cylinder walls every 3 to 6 months to ensure smooth, frictionless lever movement.
• Artisan Wood & Panel Care: Never submerge hand-turned Italian walnut or olive wood portafilters, paddles, or levers in water or place them in dishwashers. Wipe with a dry microfiber cloth and treat periodically with food-safe mineral oil or beeswax.
• Descaling Precautions: Do not perform aggressive chemical descaling at home on dual boiler or actively heated lever systems without professional guidance; dislodged scale particles can clog narrow thermosyphons and gicleur passages. Preventive water filtration is essential.
