Nerdy Bird; Rocket r58 update

Close up at the Rocket r58

Rocket r58
The Rocket r58 semi-automatic espresso machine is creating a stir among quality espresso consumers around the world as they eagerly await the launch. Rocket have always used commercial/professional components and technically meticulous construction and continues that tradition in the release of the r58.

The r58 features a two water intake opportunities of plumbing the machine directly to the water source or using the internal 2.5 L reservoir with the flip of a switch. The advanced Rocket r58 also features an intriguing electronic PID remote-comtrol 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.

The Italian espresso machine manufacture produce a machine with a robust body construction incorporating stainless steel, that ensures a life-time of quality service. You can expect a excellent performance and quality drinks from the Rocket r58´s E-61 brew-group, super quiet rotary pump and dual-boilers with long-life elements.

Features; Brewing
Commercial E-61 Brew Group
The Rocket r58 has a professional quality nine-pound E-61 brew-group made of chrome plated marine brass to ensure proper heat stability. The 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 dual boiler comes with a commercial portafilter as well as single and double-shot filter baskets.

Pre-Infusion
The Rocket 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 ectractions.

Silent Rotary Pump
The Rocket 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 efficient 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 controls and stability.

Pressure Gauges
The Rocker r58 has two 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 (Propertional Integral Differential) controllers are located independently at the boilers to monitor and maintain boiler temperatures and can be 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 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 degree, therefore you can tweak the temperature settings with confident precision for the particular coffee bean you are using and extract the maximum potential flavor.

Dual 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.

Cup watmer
The insulated coper 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 sups 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 deducated control swtich allows you 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; Frothing & Hot Water
No-Burn Stainless Stell Steam Wand
Rocket´s patented cool-touch technology ensures that the steam wand is safe to use (only the nozzle gets hot). The wand has a two-hole tip and is engaged with a large ergonomic controls 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.

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 cafe Americano, instant soup or hot chocolate, drink mixes or hot cider.
