The three-group KB90 is built for the highest-throughput bars La Marzocco serves. Its Straight-In portafilter pushes in on a straight axis instead of rotating through a bayonet arc — La Marzocco's own figures put the reduction in wrist strain at up to twelve times. Across three groups and a full shift, that compounds into real throughput and real injury prevention.
What makes the KB90 different
- Straight-In portafilter system: lock in with a single linear push. No twisting, no hunting for the bayonet, and a materially faster cycle at the volumes a three-group site runs.
- Auto steam flush: two seconds after the portafilter comes out, the group purges itself with a burst of steam to clear coffee oils and residue, optionally followed by hot water. Three groups staying genuinely clean without three extra things for the barista to remember.
- Three independent 1.3 L brew boilers: each group runs its own PID-controlled saturated boiler, so three different brew temperatures can run simultaneously.
- 11 L steam boiler with Pro Touch wands: dual-wall vacuum insulated wands that stay cool to the touch, standard, with the steam capacity for two baristas on milk continuously.
- Four programmable volumetric profiles per group plus a digital display with three programmable buttons.
- Barista lights, hot water economizer and an easy-rebuild steam valve — the service details that keep a high-volume machine in commission.
Choosing your configuration
- AV (Auto-Volumetric): programmable volumetric doses per group with flow-meter control.
- ABR (Auto Brew Ratio): adds precision drip-tray scales with La Marzocco's Drip Prediction algorithm, dispensing to a programmed brew ratio by mass rather than volume.
Best suited to
Very high-volume bars, drive-through and grab-and-go formats, transit hubs and stadium concessions, airport and campus sites, and any operation where barista throughput and repetitive-strain injury are real operational concerns.
Requires a dedicated 50 A circuit. Certified UL-197, NSF-8 and CAN/CSA-C22.2 No. 109. Note: the auto steam flush purges the group, not the puck — baristas still knock out as normal.
