Data from official source
The R58 Tune is the latest version of Rocket's dual boiler: two independent boilers, each with its own PID, so coffee and steam never compete for temperature. The group is Rocket's own design. What is new is in the name: Tune technology opens the shot with a pre-infusion and closes it with a final phase, both at a low, fixed pressure of 3 bar, for times you can program.
Everything is set from a small touchscreen, attached with a magnet, that shows the boiler temperatures. The knobs do two things: push for a purge, turn to control the flow. It runs from the 1.9-litre tank or plumbed into the mains.
It is for someone who wants a dual boiler with a little more to adjust, and a clear screen to do it on rather than a button menu. With the screen attached it is just over 40 cm wide and almost 50 deep: it needs a generous counter.
