Dual PID Controlled boilers
The GB5 features dual PID controlled boilers, one dedicated for coffee, fed by a heat exchanger system from the second steam boiler. This ensures that the water going into the coffee boiler is above 170° F, providing increased stability to the coffee boiler. Dual PID controls allow the user to set up and adjust the temperature of the coffee and steam boilers instantly, and easily. Changing the values of the coffee boiler is reflected by the temperature in the boiler quickly, allowing the GB5 to be set up specifically for the coffee you will be serving.
Advanced Group Cap
The GB5 features a first for La Marzocco, the Peiro Cap system. This group cap, on the top of the boiler contains a ruby flow restrictor to resist erosion, and conveniently, in line mounted flowmeters and solenoid valves. This ensures that all components coming in contact with the water used to brew espresso are heated by the saturated group. Making service easier is also a side effect, allowing less downtime for servicing.
A staple feature of La Marzocco machines for decades, the GB5 features the saturated group system. The group heads themselves are part of the coffee boiler, and therefore actively heated. This ensures further tempurature stability, giving you a better quality shot in the cup.
Automatic Volumetrics (AV)
This model of the GB5 features Automatic Volumetrics, ensuring consistent dosages, even when the line is out the door. Press a button, and the machine activates an option pre-infusion cycle, then starts the shot, keeping track of the amount of water passing through the coffee. This allows your baristas to start and shot and move on to other tasks in the drink building process, or in assisting other customers.
