La Pavoni Cellini Evolution Professional Rotary Pump Espresso Machine (Commercial E61 Thermosiphon Group, 1.8L Heat Exchanger Boiler, Whisper-Quiet Rotary Pump, Convertible Direct Plumb System) Bring the perfect blend of elegant Italian form and high-performance engineering to your kitchen counter with the La Pavoni Cellini Evolution. Hand-assembled in Milan, Italy, by one of the world's most historic coffee names, this professional-grade prosumer machine packs heavy-duty commercial internals into a beautifully compact, space-saving footprint. The Cellini Evolution utilizes a high-capacity copper heat exchanger boiler paired with the legendary E61 brass group head, allowing you to extract rich espresso shots and texturize silky milk microfoam simultaneously. Driven by a whisper-quiet commercial rotary pump and a convertible water supply system, it removes all hydraulic limitations to give home baristas laboratory-grade extraction pressure and repeatability. Legendary E61 Thermal Architecture & Heat Exchanger Power Tried-and-True E61 Thermosiphon Group: Features a commercial-weight brass E61 group head known for its superior thermal mass. Water circulates continuously between the boiler and the group via a natural thermosiphon loop, locking in even heat distribution and minimizing temperature fluctuations for shot-after-shot consistency. Simultaneous Brewing & Dry Steaming: Built around a high-capacity 1.8-liter copper boiler configured as a Heat Exchanger (HX) system. This internal design gives you a virtually bottomless reservoir of dry steam, allowing you to froth milk for large lattes and cappuccinos while extracting shots without waiting for the machine to recover. Mechanical Pre-Infusion System: The classic mechanical lever layout features a gentle low-pressure pre-infusion step. This saturates the coffee puck evenly before the full extraction force is applied, reducing channeling and maximizing sweetness. Silent Commercial Rotary Pump & Plumb-In Versatility Whisper-Quiet Commercial Rotary Pump: Driven by a robust rotary pump that replaces the loud buzzing of entry-level vibration pumps with a smooth, near-silent operation. It provides superior pressure stability throughout the extraction and is user-adjustable via an external dial. Convertible Water Source Engineering: Offers complete workflow flexibility right out of the box. Use the integrated 2.9-liter removable internal water reservoir for a standalone portable configuration, or use the included braided stainless steel line kit to connect the machine directly to your home’s water main. High-Contrast Dual Manometer Gauges: Features a large, clear dual-needle manometer on the front panel. This display lets baristas monitor both internal boiler steam pressure and real-time extraction pump pressure at a single glance. Compact Kitchen Footprint & Premium Milanese Build counter-Friendly Efficiency: Standing at under 14.5 inches tall, the Cellini Evolution delivers uncompromised commercial-grade performance while sliding easily beneath standard kitchen upper cabinets and into tight workspaces. Insulated Cool-Touch Steam Wand: Outfitted with a dual-walled, insulated cold-touch stainless steel steam wand. This layout prevents accidental skin burns during milk frothing and stops milk residue from baking onto the steel for fast, hygienic wipe-downs. Polished AISI 304 Stainless Steel Chassis: The exterior skin is crafted entirely from heavy-gauge, mirror-finished commercial stainless steel, built to withstand daily sanitation cycles and retain its showroom shine.
