La Marzocco KB90 3 Groups Espresso Coffee Machine – Commercial

“KB90” is the ultimate evolution of the “Linea PB” form. Designed specially to optimise the workflow for baristas in the world’s busiest bars, it boasts improved ergonomics and features. The straight-in portafilter improves the movements of brewing and eases the strain on the barista that may cause repetitive stress injuries. Efficiency is also increased thanks to “Steam Flush”: after each extraction, a burst of steam from the steam boiler purges the brewing path and is followed by a flush of hot water, keeping the group clean even during the busiest hours. This innovative feature minimises coffee residue in the group and reduces the number of times baristas need to backflush during service. Moreover, “KB90” allows for a whole new level of expression in terms of looks: the panels of this elegant model have been engineered in a way that allows for virtually infinite customisation combinations.

Available configurations: AV | ABR

Straight-in portafilter

Designed to simplify the motions required to engage the portafilter, this innovative tool reduces the strain placed on the barista by as many as 12 times. Through its ease of action, the straight-in portafilter can noticeably mitigate repetitive stress injuries, improving the natural workflow and output of baristas. 

Dual boilers

Separate boilers optimise brewing and steam production. 

Independent boilers

Separate saturated boilers for each group head allow baristas to optimise the temperature for individual coffees. 

Dual PID system (coffee and steam)

This system allows you to electronically control the temperature in both coffee and steam boilers. 

Saturated groups

Ensure unsurpassed thermal stability, shot after shot. 

Thermal stability system

Brewing water is pre-heated before entering the boiler for increased temperature stability. 

“Steam Flush”

Keep the group clean with an automatic burst of steam and a flush of hot water between extractions.

“Pro Touch” steam wands

High-performance steam wands remain cool to the touch. 

Eco mode

The machine can be programmed to enter the stand-by mode, improving energy efficiency. 

Easy-rebuild steam valve

The valve is engineered in a way that allows it to be serviced directly from the front of the machine without the need for the valve to be removed. 

Hot water economiser

This tool enables you to fine-tune the tap water temperature for rinsing. 

Digital display

Intuitive programming makes it easy to adjust machine parameters. 

Barista lights

LED lighting allows you to focus fully on your brew. 

Programmable doses

Auto-volumetrics ensure repeatability and consistency in high-volume settings. 

Personalised colours (special order)

Customisable colours based on the RAL system are available upon request.

Automatic brewing ratio/”Drip Prediction” (optional) 

Precision scales incorporated into the drip tray improve consistency by stopping the extraction based on mass. The machine uses an algorithm called “Drip Prediction” to improve shot accuracy.
