Rocket Espresso RE Doppia Commercial Dual Boiler Espresso Machine (Multi-Group Saturated Head Configuration, Independent Dual AISI 316L Boilers, 4.3" TFT Color Control Screen, Integrated Web Browser Wi-Fi Module) Command peak commercial morning rushes, optimize barista workflow, and establish laboratory-grade extraction consistency with the Rocket Espresso RE Doppia. Masterfully engineered as an elite commercial workhorse for high-volume cafés, specialty coffee houses, and busy roastery tasting rooms, this multi-group powerhouse balances industrial-grade thermal stability with a user-friendly digital interface. The "Doppia" (Italian for Double) features fully saturated group heads paired with independent, oversized AISI 316L stainless steel boilers. Driven by an advanced PID algorithm and a built-in web-server Wi-Fi programming network, the RE Doppia completely eliminates temperature drift across back-to-back extractions, delivering repeatable café-quality results. Saturated Group Architecture & Elite Dual Boiler Engineering Thermally Fused Saturated Group Heads: Built with a commercial saturated group layout where the heavy brass brew chambers are welded directly to the brew boiler. This allows water to circulate continuously from the boiler into the group heads, completely eliminating temperature drop or drift, even during non-stop, high-volume service hours. Oversized AISI 316L Stainless Steel Boilers: Crafted from high-grade, heavily insulated AISI 316L stainless steel for maximum thermal retention and rust resistance. The 4.0-liter coffee boiler handles dedicated espresso extractions under strict electronic PID regulation, while the massive 9.0-liter service boiler utilizes a pressure transducer to ensure instantaneous steam pressure recovery. Automatic Volumetric Portion Control: Delivers repeatable, high-speed consistency at the touch of a button. The programmable volumetric dosing interface allows baristas to save precise water volume targets across four selection buttons per group, automatically stopping the extraction once your target yield is reached. Modern 4.3" TFT Dashboard & Smart Wi-Fi Connectivity Vibrant 4.3” TFT Color Interface: Features a crisp, high-resolution central display panel that serves as your primary command hub. This screen lets you manage target boiler temperatures, program shot times, toggle energy-saving schedules, and review real-time extraction metrics. Each individual group head also features its own dedicated digital shot timer layout. Integrated Web-Browser Wi-Fi Module: Built with smart telemetry and connectivity options right out of the box. Managers and technicians can access, program, and adjust extraction profiles remotely via any standard smartphone or laptop web browser, while an integrated USB data port handles quick firmware updates. Two-Level Adjustable Drip Tray System: Features a versatile, adaptable mechanical drip tray layout that can be repositioned into two distinct height levels (ranging from 85mm to 125mm). This comfortably accommodates everything from traditional short ceramic espresso cups to extra-tall takeaway paper mugs. Industrial AISI 304 Build & Barista-Focused Safety Heavy-Duty Mirror-Polished Enclosure: Hand-assembled in Milan, Italy, the structural shell is formed entirely from heavy-gauge, premium AISI 304 medical-grade stainless steel panels over a reinforced structural steel layout. Insulated Cool-Touch Steam Wands: Outfitted with dual-walled, high-volume insulated stainless steel steam wands that prevent accidental skin burns during fast-paced milk texturing while stopping milk residue from baking onto the surface for quick, effortless wipe-downs. Mandatory Water Filtration Framework: Built as a commercial-grade direct-plumb asset requiring dedicated professional water line filtration and water softening networks to protect internal valves from scale accumulation and preserve your coffee's flavor profile.
