WHO'S THE Flow Control FOR? The single origin and light roast coffee espresso drinker that wants to experiment with taste profiling to get their favored taste out of their coffee.

If you’ve had your eye on a Rocket Espresso R58 recently, now may be the best time to pull the trigger. Rocket just updated their staple dual boiler and gave it some enhancements and items it desperately needed to compete in the dual boiler espresso machine market in 2020 and beyond. The name is the same with Cinquantotto added – The new 2020 Rocket R58 Cinquantotto has much improved New improved PDI operational Controller 

Here at Absolute Espresso Plus we’re all about helping potential prosumer espresso machine owners choose the machine that’s right for them.

Do I Need a Dual Boiler?

Before we get into the newly designed R58, we encourage you to ask yourself if a dual boiler is necessary.

Where dual boilers shine is the consistency department. Since each boiler is dedicated to one sole function (one for steaming, the other for brewing), you’ll find zero loss of pressure between use on a dual boiler when compared to a single boiler, heat exchanging espresso machine.

If you only plan on making one or two drinks per day – a dual boiler can certainly be considered overkill and unnecessary for your specific needs.

However, if you’re going to making drinks for the whole family, or entertain a lot, a dual boiler should be at the top of your list.

Steam Pressure On The Rocket R58

One of the greatest benefits of a dual boiler is pressure stability.

 dual boiler. One boiler solely dedicated to brewing shots of espresso, the other dedicated solely to steaming milk.

What this means for you is zero loss of pressure when brewing and steaming simultaneously in addition to zero recoup time in between shots. 

A single boiler, will experience some pressure or brew temperature loss when performing both functions simultaneously in addition to needed some time to rebuild pressure after creating a drink.

 Dual Boiler vs. Heat Exchanger

There are some more differences worth nothing here.

Pump type – most dual boilers are going to contain a rotary pump (not all, but most) while most HXs will be fitted with a vibe pump (again, not all, but most).

Rotary pump vs. vibratory pump – you’ll find rotary pumps to be more consistent, quieter, and allow you to plumb your machine directly to your water line (if you want).

PID temperature control – while PID is not a necessity on a heat exchanger, it is convenient. Most dual boiler will be fitted with PID to easily access and adjust both boiler temperatures

Rocket R58 Cinquantotto – What’s New Features R58

Built with the commercial-grade components and handmade craftsmanship you've come to expect from Rocket Espresso, the Rocket R58 Dual Boiler offers you double boiler functionality and NEW dual PID temperature control — all in a plumbable, classically styled chrome and stainless-steel housing. Features of the new 2020 model include a stronger chassis complete with New rails for a seamless drip tray fit, an upgraded magnetic drip tray closure, and an updated control board for optimized steaming and brewing.

Features & Functionality of the Rocket R58 Dual Boiler Espresso Machine - V2

  • Dual Boiler: Working independently for both brewing and steaming, the dual boiler along with thermosiphon system design allows for stability in the espresso boiler and increased levels of steam pressure and hot water from the service boiler. The brewing boiler holds 0.58 liters while the hot water/steam boiler holds 1.7 liters.

  • Dual PID Temperature Control: Program steam and brew boilers with an electronic remote-control PID that plugs into the side of the machine and does not interfere with the R58's classic styling.

  • Commercial Rotary Pump: Quieter than most other rotary pumps, the R58's pump gives you the ability to adjust the pump pressure with the external pressure adjustment controls while monitoring through the pressure gauges.

  • Pre-Infusion: To extract the full flavor and aroma when you brew your espresso, the R58 has a dual pre-infusion system encompassing a working piston and static pre-infusion chamber.

  • Pressure Gauges: With two pressures gauges on the face of the R58, one monitors the pump while the other monitors the boiler pressure.

  • Commercial Parts: Keeping up to its high standards, Rocket made sure that the R58 was made of quality commercial parts, including the E-61 brewhead, rotary pump and heavy weight portafilter (with single and double baskets).

  • Plumb It!: Standard with a 2.5 liter water reservoir, a control switch allows you to plumb the R58 right into your kitchen's water line.

  • Upgraded and Additional Steam Tip: The steam tip now features a 1.2mm diameter hole, and you get a replacement tip for down the road!

  • Handcrafted: Each machine is unique and hand crafted in Italy. Small warps in the case are normal and part of each machine's unique assembly process.

·         Dual Boiler - Made of lead-free copper, these boilers guarantee consistent heat retention and faster brewing and steaming turn around time. You'll be able to make more drinks in a quicker amount of time.

·         Electronic Controls - No need to crack into the brain of this machine, the double PID maintains both boiler temperatures and can be programmed with an electronic remote control box on the side of the machine.

·         Rotary Pump - To give create ideal pressure, this quiet rotary pump has an external pressure adjustment control so you can adjust the pump pressure with the use of the visible pressure gauge.

·         Stronger Chassis - The upgraded chassis ensures your R58 arrives in pristine condition!


·         External PID - The PID is on the side of the machine, attached with a USB cord

How Does it Compare?

An electronic PID guarantees consistent temperature regulation for each boiler, handy when making a wide variety of beverages in a short time frame. An upgraded rotary pump eliminates back pressure from the boiler and makes this machine plumbable.
