{"product_id":"la-marzocco-linea-pb-dual-boiler-commercial-espresso-machine","title":"La Marzocco Linea PB Volumetric Commercial Espresso Machine (2 Group)","description":"\u003cp\u003eThe Linea PB is built around La Marzocco’s iconic saturated group head design — a thermosiphon system that keeps the brew group in constant thermal equilibrium with the coffee boiler, eliminating heat loss and ensuring a perfectly stable extraction temperature. Paired with two fully independent PID-controlled boilers, the machine can steam and brew simultaneously without any thermal compromise. The result is unmatched temperature stability and shot-to-shot repeatability — even during the most demanding service rushes.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSaturated Group Heads\u003c\/strong\u003e — Thermosiphon-based groups permanently connected to the coffee boiler, guaranteeing thermal stability within ±0.1°C across every shot\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Independent Boilers\u003c\/strong\u003e — Separate coffee boiler (1.4 L per group) and steam boiler (11 L) allow simultaneous full-pressure steaming and extraction without interference\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVolumetric Dosing (PB)\u003c\/strong\u003e — 4 programmable volumetric doses per group plus a continuous pour option for consistent yields and reduced waste\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectronic Pre-Infusion\u003c\/strong\u003e — Programmable pre-infusion phase gently saturates the puck before full pressure, improving extraction uniformity and reducing channelling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePID Temperature Control\u003c\/strong\u003e — Independent PID controllers per boiler allow precise on-the-fly temperature adjustment — critical for dialling in different origins and roast levels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotary Pump\u003c\/strong\u003e — Built-in rotary pump operates quietly, maintains stable 9-bar line pressure, and is designed for continuous high-volume commercial use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIdeal For\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHigh-volume specialty coffee bars and third-wave cafés\u003c\/li\u003e\n\u003cli\u003eHotel lobbies, restaurants, and airport lounges requiring reliability at pace\u003c\/li\u003e\n\u003cli\u003eTraining academies and barista competition preparation\u003c\/li\u003e\n\u003cli\u003eMulti-roaster concepts needing per-group temperature flexibility\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"La Marzocco","offers":[{"title":"Auto Volumetric","offer_id":53269094727980,"sku":null,"price":27746.0,"currency_code":"CAD","in_stock":true},{"title":"Auto Brew Ratio","offer_id":53269094760748,"sku":null,"price":29841.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2673\/0284\/files\/Linea_PB_Commercial_Espresso_Machine_9.jpg?v=1761247211","url":"https:\/\/thekitchenbarista.com\/products\/la-marzocco-linea-pb-dual-boiler-commercial-espresso-machine","provider":"The Kitchen Barista \u0026 Gifts","version":"1.0","type":"link"}
