KB90 2 Group Espresso Machine by La Marzocco

Please contact us for availability, lead times 4+ weeks on some LM machines.

The ultimate workflow machine and designed as the new standard in high volume cafe performance. The KB90 is the ultimate evolution of the Linea PB form. Designed to optimize the workflow for the barista in the world’s busiest bars by improving the ergonomics and features of the machine.

Straight-in Portafilter

Designed to simplify the motions required to engage the portafilter and reduce the strain by 12 times on the barista for even greater performance and everyday usability. High volume coffee environments demand that a barista can work fast and efficiently to produce drinks during busiest periods of the day. The Straight-In Portafilter can noticeably mitigate the repetitive stress injuries occurring through its ease of action improving the natural workflow and output of barista.

Advanced Electronics + Eco Mode

Temperature display shot timers, flow pulse counter, and intuitive programming simplifies the adjustment of machine parameters. The Linea PB can be programmed to enter standby mode when not in use, reducing boiler temperatures to lower set-points and improving energy efficiency.

Automatic Dosing

With volumetric dosing you are able to program (4) doses and have your brews ready at the press of a button. This allows your baristas to multi-task and helps with baristas that aren't trained up as well. Keep your extractions precise and consist with the ease of a button.

Dual Boiler System

Separate boilers for each group allows for the optimization of espresso brewing and steam production. Combined with insulated boilers, you have a machine that not only delivers power and stability but also energy savings

Auto Steam Flush

After each extraction, a burst of steam from the steam boiler purges the brew path and is followed by a flush of hot water, keeping the group clean even during the busiest hours. This innovative function minimizes coffee residue in the group, and reduces the number of times baristas need to back flush during service.

Independent Boilers

Separate boilers for each group head allow barista to optimize temperature for
individual coffees. 

Dual PID Temperature Controller

The PID Controller employs an algorithm to regulate when and for how long the heating element is engaged in the brew and steam boilers. The PID controller allows more efficient and stable regulation of energy. With this level of control, temperature variability is reduced dramatically, making for a more consistent brew temperature. The barista is able to adjust the brew boiler temperature to a precise numerical value using a simple keypad without having to remove machine panels.

ABR - Auto Brew Ratio Option

With integrated scales in the drip tray, the KB90ABR lets barista brew by volume, mass, or brew ratio to suit their workflow. Precision scales incorporated into the drip tray improve beverage consistency by stopping the extraction based on mass. The machine uses an algorithm called Drip Prediction to improve shot accuracy and ease of dialing in.
