Features
The Rocket Espresso R58 semi-automatic espresso machine is creating a stir among savvy consumers around the world as they eagerly await its 2012 debut showing off its dual-boilers and dual PID temperature control sensors. Rocket Espresso has always used commercial components and technically meticulous construction and continues that tradition in the creation of the R58.
Connect the Rocket Espresso R58 directly into a plumbing water source or use the 2.5L reservoir with the flip of a switch. The advanced Rocket Espresso R58 also features an intriguing electronic PID remote-control box, a very quiet iso-mounted rotary pump and a commercial-grade Sirai pressure stat. The pump pressure can be adjusted externally, allowing you to fine-tune extraction rates.
Robust body construction incorporating stainless steel ensures that this Rocket Espresso model will provide a life-time of quality service. Users can expect excellent performance and quality drinks from the Rocket Espresso R58’s E-61 brew-group, super quiet rotary pump and dual-boilers with long-life elements.

Features & Benefits: Brewing
Commercial E-61 Brew Group
The Rocket Espresso R58 has a professional quality nine-pound E-61 brew-group made of chrome plated marine brass to ensure proper heat stability. Espresso extraction is aided by a 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. The R58 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 consistent flavorful, aromatic, and crema-rich extractions.
Silent Rotary Pump
The Rocket Espresso 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 is configured for best efficiency reducing pump noise and creating a very quiet rotary pump machine. Coupled with the twin PID controls, dual boilers, and Sirai commercial grade pressure stat it delivers superb temperature control and stability.
Pressure Gauges
The Rocket Espresso R58 has 2 full, round manometer displays that allow users to easily monitor both pump and boiler pressure allowing the Barista to fully understand the extraction parameters.
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.
Twin PID (Proportional-Integral-Derivative) controllers are located independently at the boilers to monitor and maintain boiler temperatures and can be set with an electronic remote-control box with digital display that plugs in via a cable to the side of the machine, thereby keeping the classic look of the R58 pristine without adding a digital LED interface to the polished front panel. The remote can also switch the hot water / steam boiler on or off, and switch between using the on-board water reservoir or the directly plumbed water supply.
The brewing boiler PID controls will maintain temperature with a deviation less than 1° Celsius. Rocket Espresso developed the R58 using Greg Scace’s temperature determination method for extraordinary accuracy. Subsequently you can tweak the temperature settings with confident precision for the particular coffee bean you are using and extract the maximum potential flavor from the coffee.
Dual Heavy-Duty Copper Boilers
The lead-free copper 0.58L brewing water boiler and the 1.7L hot water / steam boiler, which has thick brass end plates for increased heat retention, are wrapped in special thermal-insulating blanket material that provides increased heat retention and thermal stability resulting in greater energy efficiency. The overall boiler design optimizes the boiler-capacity to heater-power ratio resulting in a very fast heat up time.
Both boilers have 1400W heating elements made from special long-life material (5 times longer life than normal elements). The boilers operate completely independent, turning on and off according to the needs of each, and can be on at the same time; however, even though they both have 1400W elements, when on together they will not exceed a 1550W power consumption rate.
The electronic PID remote-control can toggle the hot water / steam boiler on and off. This mode is useful for those that only drink espresso and do not need steam or hot water and want to conserve energy.
Commercial Portafilter
The commercial-grade chromed portafilter comes with single and double shot filters and baskets for your convenience.
Cup Warmer
The insulated copper boilers also heat the cup warmer located on top of the machine. Heat is released through holes in the top of the machine, ensuring that your cups are warmed. There is a hatch cover at the rear of the tray allowing you to fill the water reservoir without removing it from the machine.
Plumbable
A dedicated control switch allows users to alternate between drawing water from the 2.5L reservoir or plumbed water lines. The large water reservoir is removable for easy refilling and maintenance.
Features and Benefits: Frothing & 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.
Features and Benefits: 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 84oz capacity and can be filled in the machine through an access hatch at the rear of the cup warming area on top of the machine, or you can remove the reservoir and fill it at the tap.
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.

BlrdFX My R-58 makes a very loud racket when the boilers are filling, but the pump is indeed quiet. The plumbed pressure is 40 pounds and the brew pressure idles at 9 Bars and pumps at 9.5 Bars. Wish the boiler fill was quiet and it has the same noise filling from the built in reservoir.
Other than the above the machine works well and is a welcome upgrade from my Rancillio Silvia that I owned for 6 years.
