gs3 (Available configurations: AV, MP)
The La Marzocco engineering group set out to take the most advanced La Marzocco technology and translate it for a home espresso machine. The GS3 features the thermal stability system used in the La Marzocco Strada, including a preheating system, digital PID controller, saturated groups, a dual-boiler system, and digital display.
Available as AV (auto dosing) or MP (conical paddle). A feature on the MP configuration, the conical valve system assures progressive control of water flow and pressure via an internal orifice, before applying full pressure. The paddle valve controls pre-infusion while the volumetric pump is working at full pressure, allowing the barista to perform pre-infusion on one group while the other is extracting coffee. This dynamic system allows the barista to reduce channeling for a more balanced extraction.
For use without plumbed in water supply, the GS3 has a self contained 3.5 liter water reservoir makes plumbing optional.
Options:
Wood or Glass Side Panels: $550
Black or White Body Panels $450

Separate boilers optimize espresso brewing and steam production.
saturated group
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.
thermal stability system
As water passes through each feature, temperature is further stabilized.
dual PID (coffee & steam)
Allows you to electronically control coffee & steam boiler temperatures.
ruby flow restrictors
Ruby flow restrictors resist scale formation and erosion.
periscope pressure gauge (MP only)
Monitor pressure at coffee during extraction.
conical valve (MP only)
