Product Description

Built with the same commercial-grade components and handmade craftsmanship found on other heat exchangers, the Rocket Dual Boiler R58 Version 1 offers you double boiler functionality and dual PID temperature control — all in a plumbable, professional-looking chrome and stainless-steel housing.

This product is an Open Box.

Features & Functionality of the Rocket Dual Boiler R58 Version 1

  • Dual Boiler: Working independently for both brewing and steaming, the dual boiler along with thermo siphon 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: With the ability to control the boiler temperature through the PID controls, these controllers can also be programed with an electronic remote-control box that plugs into the side of the machine and does not interfere with the Rocket's classic look.
  • 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 you 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 portafilter (with single and double baskets).
  • Plumb-able: With a 2.5 liter water reservoir, if you want to build this machine right into your kitchen, it has a control switch that give you the ability to plumb the R58 right into your kitchens water lines.
  • 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 you that 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.
  • External PID - the PID is on the side of the machine, attaching with a USB cord that could get damaged more easily than if the system was inside the caseworks.

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.

Does this open box version come with the rocket metal tamper?
Angelo R on Jul 28, 2013
Best Answer: Open Box machines come with all items necessary for operation, however a non essential item like the Rocket logo tamper would only be included if the previous owner included it with the return. Unfortunately because these machines are processed by our return department and repackaged, we cannot verify any accessories that will come in the box of the specific unit you will receive.
