Rocket Giotto Evoluzione R HX Espresso Machine — Commercial-Grade Heat Exchanger Espresso Machine with PID Control, Rotary Pump & E61 Group Head
Experience Italian prosumer espresso engineering with the Rocket Giotto Evoluzione R HX — a premium heat exchanger espresso machine handcrafted in Milan, Italy, by Rocket Espresso. Built without compromise for the dedicated espresso enthusiast, this machine brings together a commercial-grade rotary pump, digital PID temperature management, the legendary E61 group head, and an insulated copper boiler into one iconic, angular stainless steel chassis. Whether you’re pulling single-origin shots or crafting velvety flat whites before work, the Giotto Evoluzione R delivers a true Italian café experience on your countertop.
Simultaneous Brewing and Steaming — True Heat Exchanger Performance
At the core of the Giotto Evoluzione R is a nickel-plated, insulated 1.8-liter copper boiler running a classic heat exchanger (HX) system. This heat-exchange design lets you pull espresso shots while simultaneously steaming milk — a capability that sets HX machines apart from single-boiler designs that force you to switch modes and wait. The insulation around the boiler isn’t just for efficiency; it contributes to more stability and temperature control, meaning your boiler temperature stays consistent from the first shot of the morning to the last.
Rocket took features directly from their commercial espresso machine range and incorporated technology normally only found in full-sized commercial machines, including commercial-grade copper and brass internal components throughout.
The E61 Group Head — Pre-Infusion, Thermosiphon Stability, and 58mm Precision
The E61 group head has been a cornerstone of quality espresso machines since its introduction in 1961, providing thermosiphon circulation — boiler-heated water continuously cycling through the group to keep it at a stable temperature even between shots. The result is a group head that is always brew-ready, eliminating the cold-start temperature drop that plagues lesser machines.
Critically, the automatic pre-infusion built into the E61 allows low-pressure water to saturate the puck before full extraction pressure engages. This reduces channeling, improves even extraction, and is particularly valuable with lighter roasts and finer grinds. It’s a passive mechanical process — reliable and requiring no programming. The professional 58mm brass portafilter and group head are the same standard used by commercial café machines, giving you access to a wide ecosystem of precision baskets, bottomless portafilters, and distribution tools.
Digital PID Control — Four Roast Settings, Hidden by Design
Rocket was one of the first manufacturers to incorporate a PID into their heat exchangers, and it has now become an industry standard on high-end HX machines — a testament to their commitment to innovation. On the Evoluzione R, the digital PID controller is tucked behind the drip tray so it doesn’t interrupt the machine’s clean aesthetic. It can be adjusted across four settings to accommodate different roast styles — allowing you to dial in lower brew temperatures for light and medium roasts and higher temperatures for darker profiles, all with a tight thermal band that eliminates guesswork.
An integrated digital shot timer is built discreetly into the front panel. The digital readout appears when the pump is activated and disappears when it’s off, blending seamlessly with the stainless steel housing. Dual professional pressure gauges — finished in black — provide real-time visual feedback on both steam boiler pressure and pump pressure, giving you complete visibility into every extraction.
Commercial Rotary Pump — Quiet, Stable, and Plumbable
Well known for its low vibration and quiet operation, the rotary pump offers a unique option to plumb your machine directly into your water line. Unlike vibratory pumps found in entry-level machines, the rotary pump delivers smooth, consistent pressure throughout the shot — no pressure spikes, no noise disrupting a quiet morning.
The dual-source water system offers genuine flexibility: use the removable 2.9-liter water reservoir for standalone countertop use, or connect directly to your water supply via the included braided steel plumbing line for a permanent, hands-free setup. Rocket Espresso wanted to make the Giotto Evoluzione one of its most versatile espresso machines on the market, and the plumbing option is a key part of that vision.
Smart Protection — Low Water Alert and Auto Shutoff
Many espresso machines have been damaged by running on an empty tank. The Giotto prevents this by programming the indicator light to blink when the water level is low. If not refilled in time, a microprocessor-driven low-water sensor will power down the machine to prevent damage. This built-in protection is a thoughtful touch that adds long-term peace of mind for everyday use.
Premium Build Details and Barista-Ready Ergonomics
The Giotto Evoluzione R is built with a finely crafted 304 stainless steel case, non-compression hot water and steam valves, no-burn stainless steel steam and hot water wands, a two-hole steam tip, and a resettable high-limit Sirai pressure stat. New redesigned adjustable feet give you the ability to level the machine on any countertop surface — and with the cup rail removed and feet at their shortest setting, the machine clears low cabinet installations under 14 inches (keep in mind, if you use the water tank, you will need an additional 10 -12 inches to safely remove the water tank.)
The removable cup warmer tray on top keeps your espresso cups at the ideal serving temperature. A solid brass end plate aids in thermal stability and heat retention, while 9mm boiler end plates allow for even more structural stability and temperature consistency.
The cool-touch steam and hot water wands keep your hands safe during high-volume steaming sessions, and the high-output steam power generates dense, velvety microfoam ideal for latte art — whether you’re pouring a simple rosetta or attempting more advanced free-pour designs.
Iconic Italian Design — The Hot-Rod Aesthetic
The Giotto’s hot-rod-inspired angular walls overlay the machine from top to bottom, well complemented by the eye-catching sheen of stainless steel. This is a machine that commands attention on any counter — not just for what it produces, but for how it looks doing it. Every element, from the angular side panels to the discreet timer integration, reflects Rocket Espresso’s philosophy: that outstanding engineering and outstanding design are not mutually exclusive.
