Di Pacci — Dual-Boiler Saturated-Group Commercial Espresso Machine
La Marzocco Linea PB 3 Group Custom Canary Yellow
The La Marzocco Linea PB 3 Group is the cafe workhorse that set the specialty standard, here in a custom canary yellow finish that nobody walking past will miss.
The La Marzocco Linea PB 3 Group is a dual-boiler commercial espresso machine with saturated groups, a 5 litre coffee boiler and an 11 litre steam boiler, and dual PID temperature control. Separate boilers mean espresso temperature is held independently of steam demand, so the third group pulls the same shot as the first even in the middle of a rush.
This unit is brand new with a custom canary yellow finish over the standard Linea PB body, and it's the only one we have. Inside it's a stock Linea PB: insulated boilers, a digital display, auto backflush programme, a hot water economiser and eco standby. If you want a 3 group that works as hard as any on the market and doubles as the centrepiece of your fit-out, this is it.

Key Features of the Linea PB 3 Group
♨️ Separate coffee and steam boilers
A 5 L coffee boiler and an 11 L steam boiler work independently, so heavy steaming doesn't pull espresso temperature around.
☕ Saturated groups
Each group is flooded with water from the coffee boiler, keeping the brew path at a stable temperature from the first shot of the day to the last.
🌡️ Dual PID control
Coffee and steam boiler temperatures are set electronically on the display rather than by a mechanical pressurestat.
🧊 Insulated boilers
Boiler insulation cuts heat loss, which saves power and helps hold temperature steady.
💧 Hot water economiser
Mixes cold water into the hot water spout so you can set long-black and tea water temperature.
🧼 Auto backflush and eco mode
A programmed backflush simplifies end-of-day cleaning, and standby programming drops power use when you're closed.
Why Saturated Groups Matter on a 3 Group
On a large machine, the risk is that groups drift apart in temperature as the bar gets busy. The Linea PB's saturated group design is La Marzocco's answer to that.
- Water from the coffee boiler circulates through each group head, so the metal the coffee touches sits at boiler temperature.
- The PID holds the coffee boiler within a tight band, and because the groups are part of that water circuit they follow it closely.
- Steam comes from its own boiler, so a queue of milk drinks doesn't drag brew temperature down.
The practical outcome is that whichever group your barista reaches for, the shot tastes the same, which is what keeps a busy specialty cafe consistent.

Linea PB: 2 Group vs 3 Group
Both share the same dual-boiler, saturated-group design. The 3 group adds a station and the boiler capacity to support it.

Di Pacci recommendation: Buy the 3 group if you regularly run more than two people on the bar or serve a long morning queue, and you want the finish to be part of the brand. Don't bother if a 2 group would cover your volume; the standard La Marzocco Linea PB saves bench space and power.
Best Grinders for the Linea PB 3 Group
A 3 group bar usually runs two grinders, one for the house blend and one for decaf or a single origin.

Who This Machine Is For
✓ Ideal if you:

- Value La Marzocco's service history and parts availability

✗ Consider alternatives if you:
- Have less than about 1 metre of bench width; the machine alone is 95 cm wide
- Only have a standard 10 or 15 amp outlet; a 6100 W machine needs a dedicated circuit
- Want a plain stainless finish; see the standard Linea PB
- Are buying for home; see our La Marzocco home machines
