Adjustable Pre-Infusion Pressure: Fine-tune line-pressure or pump-driven pre-infusion via dedicated under-chassis controls to saturate coffee beds gently before full lever engagement.

Bastone Group Operation: Intuitive operation via custom "Bastone" levers that offer volumetric control alongside manual lever interaction.

Cool-Touch Steam Wands: Double-walled, non-burn stainless steel wands operated via Tulip turning steam knobs.

Easy Stop & Flush Push-Buttons: Integrated quick-action levers allow instant shot termination or immediate screen purging without requiring a full main lever stroke.
