La Marzocco Linea PB X 4 Group Commercial Espresso Machine

High-capacity professional 4-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 4 Group is an advanced high-capacity commercial espresso machine designed for demanding 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 4-group configuration provides extensive brewing capacity and workspace for demanding operations with multiple baristas. Independent saturated boilers for each group head allow 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 peak service periods.

The 4-group model features two 3.4-liter coffee boilers and a large 15-liter steam boiler. Dual PID control allows electronic adjustment of coffee and steam boiler temperatures, while Pro Touch steam wands provide high-performance steaming while remaining cool to the touch. The Hot Water Economizer also allows the operator to fine-tune tap water temperature for tea and other hot beverages.

The Linea PB X 4 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.

The Linea PB X uses independent saturated boilers to help baristas 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 its advanced boiler system, this helps support consistent performance throughout demanding commercial service.
