Description
The GB5 has redefined the standard for temperature stability in modern espresso equipment. A dynamic preheater assembly ensures that water entering the coffee boiler is at precisely 170° F. 170° F water replaces hot water exiting the group, reducing temperature swings in the coffee boiler.?An algorithm-based PID temperature controller further reduces temperature fluctuation in the coffee boiler. A group cap designed by Piero Bambi and an integrated ruby flow restrictor reduces channeling and ensures that water never leaves the saturated area of the coffee boiler, eliminating the introduction of temperature instability during the brewing process.
Specification
Mechanical Paddle
The mechanical paddle is inspired by the original mechanical group used on the La Marzocco GS – the first dual-boiler espresso machine with saturated groups (1970). This valve system enables the barista to saturate the coffee with low pressure (line pressure) water before applying the full 9 bars of pressure. While more complex, this dynamic system allows the barista to control the variable of pre-infusion and reduce channeling for a more balanced extraction.
Dual Boilers
Separate boilers optimize espresso brewing and steam production.
Saturated Groups
Ensure unsurpassed thermal stability, shot after shot.
Digital Display
Intuitive programming makes it easy to adjust machine parameters.
Hot Water Economizer
Enables you to fine-tune the tap water temperature for rinsing.
Dual PID (coffee & steam)
Allows you to electronically control coffee & steam boiler temperatures.
Barista Lights
LED lighting allows you to focus on your extraction and the cup.
Personalized Color*
Customizable colors based on the RAL color system on request.
*special order
Ruby Flow Restrictors
Ruby flow restrictors resist scale formation and erosion.
Thermal Stability System
As water passes through each element, temperature is further stabilized.
