Linea PB 4 Group Espresso Machine by La Marzocco

Please contact us for availability, lead times 4+ weeks on most LM machines.

The Linea PB represents the first full update to the technical and stylistic workings of the Linea in the nearly 25 years it has been in production. The Linea PB features the iconic La Marzocco polished stainless steel body, updated with simplified lines and a lower profile.

Styled to Perfection

To complement its stylistic updates, the Linea PB features improved component longevity and new electronics that give the barista control over functions directly from the machine interface – including boiler temperatures, brewing volume, hot water tap dose, and auto-backflush, among others.

Automatic Dosing

With volumetric dosing you are able to program (4) doses and have your brews ready at the press of a button. This allows your baristas to multi-task and helps with baristas that aren't trained up as well. Keep your extractions precise and consist with the ease of a button.

Advanced Electronics + Eco Mode

Temperature display shot timers, flow pulse counter, and intuitive programming simplifies the adjustment of machine parameters. The Linea PB can be programmed to enter standby mode when not in use, reducing boiler temperatures to lower set-points and improving energy efficiency.

Dual Boiler System

Separate boilers for each group allows for the optimization of espresso brewing and steam production. Combined with insulated boilers, you have a machine that not only delivers power and stability but also energy savings

Dual PID Temperature Controller

The PID Controller employs an algorithm to regulate when and for how long the heating element is engaged in the brew and steam boilers. The PID controller allows more efficient and stable regulation of energy. With this level of control, temperature variability is reduced dramatically, making for a more consistent brew temperature. The barista is able to adjust the brew boiler temperature to a precise numerical value using a simple keypad without having to remove machine panels.

ABR - Auto Brew Ratio (optional)

With integrated scales in the drip tray, the Linea PB ABR lets barista brew by volume, mass, or brew ratio to suit their workflow. In Mass mode baristas program a preferred weight in the finished cup and the machine stops automatically, removing the need to place an additional scale on top of the drip tray. Auto-Brew Ratio works by programming in a given ratio and letting the machine dispense the appropriate water to reach the given ratio.

Paid Installation and Extended Warranty + Training ($1000 Value)

You have enough to worry about and coordinate, order your commercial espresso with Coffeeionado and we'll pay to have a professional technician install your machine for you. Not only will they install it, they will also train you on the equipment to make sure you are comfortable working with your new machine. Also, havepiece of mind that should anything happen your coverage is extended beyond the normal year warranty.
