Overview
The KB90 is a commercial espresso machine engineered to increase service speed and barista workflow efficiency for high-volume cafés. It integrates an ergonomically redesigned straight-in portafilter system, an automatic Steam Flush to reduce grouphead residue, and options for mass-based extraction control (Drip Prediction). Panels are modular for extensive customization.

Key concepts

• Straight-in portafilter system redesigned to reduce wrist strain and speed dosing.
• Steam Flush / Auto steam flush: a steam burst followed by a hot-water flush after each extraction to purge the brew path and limit residue buildup.
• Drip Prediction algorithm: integrated scales in the drip tray stop extraction by mass for repeatable shot accuracy.
• Evolution of the Linea PB form, optimized for highest-volume cafés and continuous service.

Highlights

• Straight-in portafilter with automated purge and flush to reduce cleaning frequency.
• Auto steam flush for continuous grouphead cleanliness during peak service.
• Drip Prediction (optional): mass-stop extraction for consistent dosing and easier dialing-in.

Essential features

• Dual boiler system: separate boilers for brewing and steaming to optimize performance.
• Independent brew boilers per group: allows temperature tuning for each grouphead.
• PID temperature control for coffee and steam boilers.
• Saturated group design for enhanced thermal stability shot after shot.
• Thermal stability system with pre-heated brew water.
• Pro Touch steam wands that remain cool to the touch.
• Additional options: easy-rebuild steam valve, hot water economizer, digital display, barista lights (availability depends on configuration).

Notes
The KB90 focuses on reducing service time and barista fatigue through ergonomic portafilter design, minimizing group cleaning events via the Steam Flush, and supporting consistent shot control with optional mass-based extraction. Modular panels enable wide aesthetic customization.
