    Gb5 – Raising the bar

    La marzocco introduced the gb5 machine model in 2005. It was named after Piero Bambi’s wife, Giovanna Bambi. It is the ideal espresso machine for the most stylish and classic cafés.

    Equipped with a CPU board and designed for superior temperature control, the gb5 with powerful technological advancements is in par with classic la marzocco design and spirit. The machine is a great companion to any coffee bar. Its unmatched temperature stability provides steady brew water and steam even during the peak hours.

    The gb5 redefines the standard for temperature stability in modern espresso equipment by the use of pid technology. The dynamic preheater assembly ensures that water entering the coffee boiler is at precisely 170°. Therefore water at this degree replaces the hot water exiting the group thereby reducing temperature swings in the coffee boiler.

    The gb5 features an algorithm-based pid temperature controller, which further reduces temperature fluctuation in the coffee boiler. A group cap (designed by Piero Bambi) and the integrated ruby flow restrictor reduces channelling to ensure that water never leaves the saturated area of the coffee boiler, eliminating the possibility of thermo-instability during brewing.

     

    fb 80 paddle

    The mechanical paddle enables the barista to saturate the coffee with low pressure (line pressure) water before applying the full 9 bars of pressure. this dynamic system allows the barista to control the variable of pre-infusion and reduce channeling for a more balanced extraction.

    engineering

    • Saturated groups: ensure unsurpassed thermal stability, shot after shot.
    • Dual boiler system: separate boilers for each group optimize espresso brewing and steam production.
    • Dual pid (coffee and steam): allows you to electronically control coffee and steam boiler temperature.
    • Insulated boilers: reduce energy consumption while contributing to temperature stability.
    • Ruby flow restrictors: synthetic ruby flow restrictors resist scale formation and erosion.
    • Pre-heating system: prior to entering into the coffee boiler, water is pre-heated – thus increasing productivity.

    ergonomics

    • Stainless steel portafilters & precision baskets: for improved cup quality and consistency.
    • Digital display: temperature display, shot timers and intuitive programming simplifies the adjustment of machine parameters.
    • Hot water economizer: fine tune the temperature of the hot water spout.
    • Tall cups: allows you to use the machine with tall, to-go cups (+2.5cm /1in. in height).
    • Auto back-flush program: automatic cleaning program.

    options

    • Available models: 2, 3 or 4 groups.
    • Machine operation: automatic (av), semiautomatic (ee) and mechanical paddle (mp) versions.
    • Cup warmer: maintain espresso and cappuccino cups heated at a proper temperature.
    • Barista lights: led lighting allows you to focus on your extraction and the cup.
    • High legs: makes it easier to access beneath the machine (+7.5cm / 3in. in height).
    • Personalized colors: customizable colors based on the ral color system, on request.
    • Auto steam: simple steaming system stops automatically at your desired temperature.
