    Re: New Vibiemme Dual Boiler Machine

    and chris - could you run a minoreII at 2 bar for steam boiler?
    yes i know, i know..all these minoreII Qs...

      hmm- dunno....

      The steam boiler on the minore contains a HX which feeds water to the to the brew boiler...

      Minore II machines usually run about 1.0 bar...So the immediate issues which come to mind are:[*]You muck up the temp offset between display and group- so would need a scace to recalibrate that successfully[*]You need a much more robust breaker valve on the steam boiler- so would need to replace that[*]Will the pressurestat cut it? Probably need a Parker or Sirai[*]What about if she go bang? Who knows if the boiler would sustain 2bar?

      Bottom line is that the Minore II is not designed for 2 bar steam pressure. Youd be totally on your own and nobody would provide a warranty on such wild settings...

        so then, by consequence, what youre saying is that the VBM DB| is MUCH better built that it can handle that kind of pressure (2 bar)?

        are my visions of shiny minoreII in my kitchen diminishing? and VBM coming into radar at a fast pace?

          Erm...I think Im saying that theyre two different machines at different price points built by two companies each with their own philosophies ....

          Also, the PID on the VBM is capable of providing better temp control- not that this will neccessarily be so much of an issue with a 5kg metal group :-/...

            thanks for clarifying chris.

            so the rotary vbm DB will be around 500 smackers more than the rotary minore, but you get more precise temp control, commercial pressurestat (and other stronger internals), better steaming power and good track record for reliability....

            and then i guess with both you have the old "but the e-61 aint meant for DB machines" story

              And the rest Aaron. All VBM DS went up $200 today...If I am playing Nostradamus well, that would put the dual boiler vibe pump PID version at $3465 + a premium for a special order rotary pump plumbed version. I wouldnt predict a whole heap of change out of 4 gorillas....

              Makes a pretty compelling argument out of that Vivaldi II hey? :-?

                  i dont know if its worth the risk chris - i definitely wouldnt be wrestling 4 gorillas just for some loose change

                    The PID readout has me perplexed. The photos Ive seen all have values > 100. Presumably its showing the brew temp in degrees C. Do people really brew at that temperature? Also I note the boiler pressure gauge shows about 2 bar. The HX VBMs are already steam blasters at 1 bar.

                      Thats the boiler temp BobT. Not the adjusted temp at the grouphead. Unlike the Minore which has the grouphead temp with the offest pre-programmed (I think its about 7 degreesC). Had me baffled too. Looks cool though  8-)

                        Re: New Vibiemme Dual Boiler Machine

                        Hi Bob- the PID display reads temperature at the boiler as a true indication of whatt going on, rather than an offset temperature which is estimated at the group and could be influenced by ambient.

                        Id think the 2 bar at the stram boiler more than compensates for the lower 1.4L steam boiler volume when compared to the HX version 2.7L boiler at circa 1.1 bar.

                        In the flesh, its sensational and very controllable...

                          Hey Chris,

                          Have you managed to get a Scace on that sucker yet? Id love to see some results of temp stability at the group.

                          Have you had a look at the guts of it in regards to the line from the boiler to the group? Is it insulated in anyway? Or what is expected temp at the grouphead if the PID display shows boiler temp? There is obvioulsy some losses in the tubing from the boiler to the grouphead, of which the Minore compensates for with the offeset. (It surprised me in how, acceptably, accurate that is when measured with a scace FWIW. Although it was only for a while and no real test was done).
                          What are the fluctuations, if any in the brew boiler when a load of superheated water is dumped and the HX water enters from the steam boiler? I guess one of the more important things is stability, which I reckon the PID on the VBM would do a killer job at, rather than accuracy. When it comes down to it, its more a scale, and Im just used to the scale of the Minore. And I guess one of the main things people are striving for with these machines is repeatability in the cup.

                          Im trying not to compare the Minore to the VBM DB in regards to its inners as they are IMO different machines, but gee its hard :-/


                          Sorry if all these questions are unanswerable right now as I know its early stages. Im just excited -as you can see I just rambled.

                          Sorry Chris :-[

                                Found this on You Tube, showing the VBM dual boiler PID in action.   Its a bit blurry but still shows the machine in all its glory

                                Looks so nice
