Rocket Espresso delivers with the R58 V2, featuring dual independently operated PID controlled boilers and a commercial grade rotary pump. Rocket Espresso’s unique aesthetic shows in the tapered height-adjustable feet and large, gear-like steam & hot water knobs. At the core of the machine are the 0.58 and 1.8 liter copper boilers reinforced by 9 mm boiler end plates, and 1200 watt long-life heating element that work in concert with the E61 group for temperature stability. The R58’s dual boilers allow the you to brew and steam simultaneously. Thanks to the full-sized commercial rotary pump, you can expect near silent brewing and the option to plumb the machine into a direct water line. To complement the R58’s brew and steam power, the removable PID temperature controller can be adjusted to accommodate different roast styles. Machine functionality is controlled through the communication pod, which can be detached to preserve the R58’s style.

Brewing

Commercial E-61 Brew-Group

The Rocket Espresso R58 has a professional quality, nine-pound E-61 brew-group made of chrome plated brass to ensure proper heat stability. Espresso extraction is aided by a thorough pre-infusion process to preserve coffee flavor and aroma. Hot water is constantly circulated between the boiler and brew-group to ensure proper brewing temperature. This Rocket Espresso unit comes with a commercial portafilter as well as single and double-shot filter baskets.

Pre-Infusion

The Rocket Espresso R58 has a dual pre-infusion system, consisting of a mechanical pre-infusion system with progressively working piston and a static pre-infusion chamber, resulting in flavorful, aromatic, and crema-rich extractions.

Dual Boiler

At the heart of the R58 is its 0.58 liter and 1.8 liter insulated copper boilers, equipped with a 1200 watt heating element. The copper design shows improved heat retention and temperature stability, resulting in greater energy efficiency. In combination with the thermosyphon system, the R58 enjoys unprecedented temperature stability.

Silent Rotary Pump

The R58 model has a quiet, commercial grade rotary pump with external pressure adjustment controls, allowing users to fine tune pump pressure while viewing the dedicated pressure gauge. The internal architecture of the machine has been reconfigured increasing efficiency and further reducing pump noise creating the one of the quietest rotary pump machines on the market. Coupled with the Sirai commercial grade pressure stat it delivers superb temperature control and stability.

Commercial Portafilter

The commercial-grade chromed portafilter comes with single and double shot filters and baskets for your convenience.

Electronic Controls

The boiler and reservoir water levels are monitored by sensors that will alert the user if the machine needs to be refilled, and shut it off if ignored. This feature helps to prevent a dry-boil and prolong the life of the machine.

Removable Cup Warmer

The copper boiler also heats the removable cup warmer located on top of the machine. Heat is released through holes in the top of the machine, ensuring that your cups are heated.

Plumbable

A dedicated control switch allows users to alternate between drawing water from the 2.5 liter reservoir or plumbed water lines. The large water reservoir is removable for easy refilling and maintenance.

Frothing and Hot Water

No-Burn Stainless Steel Steam Wand

Rocket Espresso’s patented cool-touch technology ensures that the steam wand is safe to use (only the nozzle gets hot). The heavy-duty wand has a two-hole tip and is engaged with a large ergonomic control knob at the top of the wand. Below the steam wand is the steam pressure gauge – the machine is at steaming pressure when the gauge measures around 1 bar. Use the steam knob to foam and steam milk, soy milk, or half and half for a cappuccino, latte, café breve, or latte macchiato.

Stainless Steel Hot Water Nozzle

The hot water nozzle is located to the right of the brew group and features another large ergonomic control knob like the steam wand. You can dispense hot water for tea, a café Americano, instant soup or hot chocolate, drink mixes, or hot cider.

Cleaning, Maintenance, and Other

Water Sensor & Reservoir

The Rocket Espresso R58 comes equipped with an electronic microprocessor controlled automatic low-water-level sensor that will automatically shut off the machine to prevent a dry boiler. A warning system will also alert you when the water reservoir needs to be replenished. The water reservoir has a generous 2.5 liter capacity and is removable for easy cleaning and refilling. Remove the cup tray from the top of the machine, and remove the water reservoir using the handles. Rinse with non-abrasive detergent, and refill at the tap. A water softener can be used to increase the length of time between descaling cycles.

Regular Upkeep

Use a damp cloth to keep your brew group head free of excess grounds, and use a brush to clean the shower screen and group gasket on your brew group. The portafilters’ metal filter-basket and filter handle can be cleaned in warm water and non-abrasive detergent to remove excess grounds and coffee oils. When the drip tray fills, empty it and clean the drip tray and stainless steel drip tray grid with a damp cloth. The stainless steel body of the machine can also be wiped down with a damp cloth to keep it looking its best.
