La Marzocco Linea PB X 3 Group Commercial Espresso Machine

Advanced professional 3-group commercial espresso machine with independent saturated boilers, dual PID temperature control, Pro Touch steam wands, and AV or ABR configuration options.

The La Marzocco Linea PB X 3 Group is an advanced professional commercial espresso machine designed for busy cafés, specialty coffee shops, restaurants, hotels, roasteries, and other high-volume coffee programs. Building on the trusted Linea PB platform, the Linea PB X incorporates advanced La Marzocco technologies while maintaining the practical lower profile, increased work area, and recognizable Italian design of the Linea PB.

The 3-group configuration features independent saturated boilers for each group head, allowing baristas to optimize brewing temperature for individual coffees while maintaining excellent thermal stability. A dynamic preheating system helps provide steady brew water and steam even during demanding peak service periods, while Dual PID control allows electronic adjustment of both coffee and steam boiler temperatures.

The 3-group model features three 1.3-liter coffee boilers and an 11-liter steam boiler. Pro Touch steam wands provide high-performance steaming while remaining cool to the touch, and the Hot Water Economizer allows the operator to fine-tune tap water temperature for tea and other hot beverages.

The Linea PB X 3 Group is available in AV (auto-volumetric) and ABR (auto brew ratio with scales) configurations. The AV configuration provides automated volumetric dosing for consistent espresso preparation, while the ABR configuration adds precision scales integrated into the drip tray for enhanced consistency and extraction control by weight.

Ideal Use Case

Ideal for high-volume cafés, specialty coffee shops, restaurants, hotels, bakeries, roasteries, and other demanding commercial coffee programs that require increased espresso production capacity, precise temperature control, and powerful steam performance. The 3-group configuration provides additional brewing positions and workspace for multiple baristas during busy service periods.

Design & Build

The Linea PB X builds upon the proven Linea PB platform with updated technical and stylistic features. It incorporates technologies including a preheating system, independent boilers, an accessible hot water mixing valve, and Pro Touch steam wands. Refreshed aesthetics include barista lights as standard along with white details on the logos, manometer, display lettering, and keypads.

The 3-group model measures 38 inches wide, 23 inches deep, and 21 inches high, with a weight of approximately 170 lbs. It features three independent 1.3-liter coffee boilers and an 11-liter steam boiler. The brochure lists a minimum wattage of 5830W and a maximum wattage of 7790W for the 3-group configuration. 

Independent saturated boilers provide a separate saturated boiler for each group head, allowing the barista to optimize temperature for individual coffees while maintaining thermal stability. Dual PID control provides electronic control over coffee and steam boiler temperatures, while insulated boilers help reduce energy consumption and contribute to temperature stability. 

Pro Touch steam wands provide high-performance steaming while remaining cool to the touch. The Hot Water Economizer allows the operator to fine-tune tap water temperature for tea, while the ½-turn steam valve fully opens with half a turn to reduce the amount of movement required from the barista during milk steaming. 

AV vs. ABR Configuration

AV – Auto-Volumetric: The AV configuration is designed for consistent volumetric espresso preparation. The barista initiates the extraction and the machine automatically stops the shot according to the programmed volume, helping improve consistency and workflow during busy service periods.

ABR – Auto Brew Ratio with Scales: The ABR configuration adds precision scales integrated directly into the drip tray. The integrated scales provide an improved level of consistency and allow beverage weight to be incorporated into espresso preparation. The integrated scales are exclusive to the ABR configuration.

Advanced Brewing Technology

The Linea PB X incorporates a dynamic preheating system designed to provide exceptional temperature stability and steady brew water and steam even during peak service periods. Combined with independent saturated coffee boilers, this system allows individual group temperatures to be optimized for different coffees while supporting consistent performance throughout demanding commercial service.
