Just downloaded footage from my secret webcam in the kitchen of @"DavecUK"#1 only to discover that he's been holding out on us! Cmon Dave, spill the beans (not the coffee ones) on this geourgeous looking leva. [URL=https://i.imgur.com/Y7e0uuz.jpg][IMG]https://i.imgur.com/Y7e0uuz.jpg[/IMG][/URL]

For this machine it's one of the first made, and I am doing an Engineering review on it for Antonio (the creator) as a favour, so I can't really comment at this stage. But I can post photos….and say that the Paddle levers on this are very basic beta ones….so that area is still in the design melting pot.

needs to be 50mm shorter for a uk work top haha i believe this is a commercial focsed machine?

I love the look of these sorts of lever machines, but they really need to at least try to make them a bit more compact in design. They're either lacking in that area of expertise or they don't care… A more compact design would look like a much better centre piece in a kitchen (and take less space in a commercial setting), rather than protruding till the near edge. The size distracts from the elegance of it.

Certainly a looker. I'm sure we will all look forward to your thoughts when you are able to comment.

@"Cuprajake"#p10000 no it's for the home market

@"Cuprajake"#p10000 from the nurri website https://www.nurri.coffee/portfolio-item/nurri-leva-sa-machine/ L-TYPE LEVA S.A. is a professional machine. Yes. But it is designed for those who want to enjoy quality espresso at home, making it with the same passion and competence of a professional bartender.

@"tompoland"#p10004 I like how they stuck Patent Pending on everything 🤣 a bit unprofessional.

@"Sham"#p10001 I agree when it comes to similar sized Levers that require external plumbing or flojet type arrangement. But the Nurri is dual boiler and plumbing is optional. Still, I agree that it's a lot for a normal kitchen. I like the footprint on the Decent for example.

Powder coated version. Wow. [URL=https://i.imgur.com/7uFzqtw.jpg][IMG]https://i.imgur.com/7uFzqtw.jpg[/IMG][/URL]

@"tompoland"#p10007 In that case they should have either decreased tank sizes and utilised quicker water heating technology (I'm sure there's loads of options from other industry's) or started with a more wide design but I guess that would've cost too much R&D time. One way to think of it is that they won't lose customers if its small, but they will lose customers if its too big. It does look pretty nice though.

Nurri Leva S.A.

Viernes It has a 3-sensor PID, not 3 separate PIDs. Does it matter? Who knows, but given that the 3 PIDs on the ACS seem to respond well to rather different parameters (at least on group and brew boiler), it might… at some level.

On materials, the only thing I know for sure, as it’s in the published specs for both, is that the body of the ACS is in AISI 304, the one of the Nurri in 430, which is a bit cheaper and a bit less resistant to corrosion. The zebrano is approximately 10,000 times nicer than the walnut, but it’s purely aesthetic, and I’m “limited” to stainless by budget and stock anyway. I can’t find any photos of the interior… [hint, hint]

dfk41 Sorry, didn’t mean to reply snarkily if it came across like that - just typing between meetings at work… Perfectly valid questions, which I have/had myself - I wish there were a few more details on the Nurri, even just photos of the inside. It’s just too new.

It might… or not. The Nurri also responds well to keep stable the desired temperature. At least in my experience.

But to what corrosion? I don’t bathe the machine in acid and I don’t pull the lever under the sea. I give it normal use. And with proper use, you are not to get corrosion.

The materials must be appropriate to the use that is required. Using the best of the best, maybe it’s cool, but unnecessary if the purpose doesn’t require it and all it does is increase the cost.

Perhaps you value a lot that the steel of a machine is 316 instead of 430. I’m not saying it’s not important to you! But we all have our preferences. I do not find it so important, which I think is ok too.

“Better materials” are not only related to what kind of stainless is used, of course. So It seems you like the little details about the quality, I’ll give some details I remember right now:

The L-Type was designed from scratch to be a lever machine. This means that the machine does not tip -despite the group height clearance and no use of counterweight (which it’s an interesting challenge)- and has the required minimal front panel flex because lever forces were emulated on computer software.

The group is attached to the body machine with teflon washers instead of a pad to minimize the heat transfer to the machine’s body, thus reducing internal heat. If my memory is correct, I think - 7ºC was calculated.

The boilers heaters are removable. Not welded.

There was a choice over different group brands. The TOF group was discarded for technical reasons. But I think still one can ask Nurri to mount one in the machine if you really want it.

I might be biased as an EVO owner, but I’m not sure I see much much merit overall in the added features from the Nurri Leva, save for the shot timer (which is convenient, although an easy to read pressure gage more than comensates)

The flushing paddle function can be achieved by pulling the lever (which can be dangerous as for flushing there is no backpressure from a coffee puck), but a clever person might be able to jerry rig a paddle to press on the small lever in the back of the group

The pressure release paddle might save a few seconds at the end of a shot, but it means more cleaning (Using plastic cup trays as DavecUK I pretty much do not need to clean the drip tray after each shot… ), and more maintenance (as dirty water flows back through the group)… it could also create some hazard as the level can move quickly when the paddle is pressed.

The fact that the motion of the paddles is not consistent (one rotates on a vertical axis; the other on a horizontal axis) seems odd.

Of course, there are aesthetic considerations and its good to have some competition/emulation, but I struggle to see much market for this machine (and I have nothing against Antonio Nurri to be clear!)

Eiffel paddle to press on the small lever in the back of the group

Tbh, we haven’t seen the need to back flush the Evo after 9 months of ownership, have we?

Btw, the below is @DavecUK’s summary of how might we back flush the Evo, at owners’ risk!

Empty group, measure amount of water in 5 seconds (use towel to depress water valve arm at back of group, not lever)

take portafilter and use rubber backflush disk, see how much it holds, then add 20ml (ish).

work out how many seconds you need to fill portafilter with backflush disk + the 20 ml

Add normal amount of Puly cafe to backflush disk

use towel (so you don’t burn yourself) to depress water valve arm at back of group for the number of seconds you calculated at step 3

Wait…I dunno 5 minutes…perhaps 10

Make sure pressure gauge has no pressure showing (if it does, it’s big towel time or main off)

Unlock group (use tupperware catch tray)

Flush water through group with no portafilter loaded as in step 5 with towel

After first short flush, you can use lever to flush again.

So Nurri design a system to flush a lever safely (you said the normal way it’s dangerous) and it has no merit? Okay…

The L-Type also has a pressure gauge. You have both, pressure gauge and timer.

Eiffel The pressure release paddle might save a few seconds at the end of a shot, but it means more cleaning (Using plastic cup trays as DavecUK I pretty much do not need to clean the drip tray after each shot… ),

If you do not want to use the release paddle, you don’t have to. You can let end the shot as any other lever machine. But if you chocking the machine, you can release the pressure easily with the paddle. You have this advantage. And also you can backflush the group if you want/need. This again isn’t obligatory.

Eiffel it could also create some hazard as the level can move quickly when the paddle is pressed.

The release paddle was created to end the shot, the possibility to backflush a lever and also vent pressure in case of choking and avoid portafilter sneezing which splashes hot water. It’s not to create a hazard but to solve it.

Eiffel and more maintenance (as dirty water flows back through the group)

There’s no dirty water flow back through the group.

Eiffel Of course, there are aesthetic considerations and its good to have some competition/emulation,

Emulation? What do you mean?

Eiffel but I struggle to see much market for this machine (and I have nothing against Antonio Nurri to be clear!)

So there’s no market for this machine because you prefer to not have features that make it easier to work with a lever… ¿?

AFAIK there are only 2 machines in the world with these features. The other one is the Kees Van der Westen Slim Jim Idrocompresso, which shares the pressure gauge, timer, flush paddle and release paddle. I guess Kees has also created these features with the intention of not selling machines on the market.

Eiffel

LMSC Tbh, we haven’t seen the need to back flush the Evo after 9 months of ownership, have we?

I must say I don’t see the point of back flushing on the Evo… On a machine with a 3-way solenoid or likely the Nurri this is different.
What is useful though is to be able to flush the group, for instance to clean the shower screen after shots (and the right paddle of the Nurri makes this marginally simpler)

LMSC

Eiffel I must say I don’t see the point of back flushing on the Evo… On a machine with a 3-way solenoid or likely the Nurri this is different.

That’s why the Evo owners have back flushed! I think, some body asked in the middle of last year about this. The response was there is no need to; if one were to be keen, hence the above summary

Cuprajake

I also like how they removed the nuts off the group

LMSC

Viernes But to what corrosion? I don’t bathe the machine in acid and I don’t pull the lever under the sea. I give it normal use. And with proper use, you are not to get corrosion.

Water that has a lower alkalinity. We assume you are going to use filtered water to avoid scaling.

CoyoteOldMan

Hi Viernes Thanks for all the thoughts/information. I think anyone spending £/€ 3,000+ on a coffee machine is either a bit obsessive and interested in the fine details, or so rich that they don’t care, in which case the suggestion made by Paolo5 probably applies…

I have been researching the Nurri machine fairly extensively over the last couple of weeks… not finding much; the Nurri site has very little info beyond a few nice photos and badly written/poorly translated marketing spiel.

For example, the fact that the group is insulated, the heating elements are removable and the group is not a TOF one are all news to me, yet these are (in my opinion) two plus points, and one interesting one re: the choice of a different group - why? I’m not keen on getting a TOF group per se, but an indication from Nurri of what are the reasons for choosing something else, and how the something else is different from a standard La San Marco group would be really interesting to know.

Viernes The L-Type was designed from scratch to be a lever machine. This means that the machine does not tip -despite the group height clearance and no use of counterweight

Well… while the ACS machine has an 8 kg counterweight, the overall weight of both is similar, so there must be some additional weighting going on in the Nurri - the other components are pretty similar in size and weight, after all. Again, one plus point (group height clearance) which is missing from all published information; it “seems so” from the photos, but only a user (you) can confirm it.

Viernes The L-Type also has a pressure gauge. You have both, pressure gauge and timer.

In fact, from the photos, it seems to have 2 - but again, there is no information on what they measure. The one on the left is clearly group pressure. I assume the one on the right is for steam/service boiler pressure, considering the scale and the fact that it doesn’t seem to move when pulling a shot.

Where did you get this information and the rest, including the use of CAD to design the structure? Just to be clear, I’m not doubting your word; I’m just trying to find out as much info as I can, be it on English, Spanish, Italian, French, Dutch or German forums… or any other language! Google search is not my friend, in this case. Again - thanks for posting, this is very useful for me in the current “undecided” situation, but it’s also going to be useful to others researching the machine.

Buen fin de semana, y gracias!

Viernes The TOF group was discarded for technical reasons.

Excuse my ignorance trying to follow this thread. What’s a TOF group?

mathof2

Viernes The Nurri also responds well to keep stable the desired temperature. At least in my experience

If you mean stable throughout the shot (as opposed to between shots), I thought one of the advantages of a traditional spring lever machine was meant to be that the brew water temperature (as well as the piston pressure) declined throughout the shot.

Viernes Emulation? What do you mean?

emulation /ɛmjʊˈleɪʃ(ə)n/

Cuprajake asiest way to check what it does is to choke the lever and press the paddle , any volunteers 🤣

I already answered this in post 111.

That’s not actually true, Antonio holds neither patent. M&V SRL (Paolos Company) owns the Patent for the Vostok and is the company that owns the sub brands Elcor and ACS. For the Vesuvius it is a similar situation.

There’s no ballast or counterweight in the Nurri. It weights what it weights because of the materials used. Also keep in mind that it has a big rotary pump

Information comes from Antonio Nurri itself. I did a lot of research and I asked Antonio a million questions before purchasing the machine.

Yes, google search is not your friend, nor mine in this case :) There’s no user information (until now), that’s why I went straight to the source.

I have another video. I suppose some of you have already seen it. But here it is.

Cuprajake

i think with any new machine there is very little info,

i remeber saying the same when looking at londiniums, and ssp burrs,etc which is why i put videos up about the products i have

im sure as more hit the market, there will be more videos for people to see,

re the counter weight would the front leg design not stop the machine pulling forward,

CoyoteOldMan

Cuprajake re the counter weight would the front leg design not stop the machine pulling forward

Yes - it seems more intrinsically stable than the ACS design which ‘reuses’ a non-lever chassis and leaves the front feet ~3 cm back from the front of the machine. My observation was just that since both machines have roughly the same component counts/sizes (2 stainless boilers of ~2 and 1 litre, a “LSM-style” group, a pump, a tank and a few valves and electronics parts) and the same weight and outside dimensions, the Nurri must also use some additional weight towards the back. The paddles don’t seem that heavy (and the ACS has more PID boards, which are not zero weight, especially with SSRs).

Either that or the body is incredibly strong: 8 kg of steel is ~1 m² of 1 mm-thick sheeting, i.e. roughly 1 mm extra thickness around all the machine (the ACS body isn’t flimsy either…)

Edit - corrected feet distance from front, as explained below

CoyoteOldMan

DavecUK I think what @Viernes may have meant is that Antonio is listed as the inventor (in fact, the “Vostok” patent lists both Paolo Cortese and Antonio Nurri as inventors). The invention/patents are assigned to Elcor/M&V.

Interesting that none of the several “patent pending” features of the Nurri are shown on Google Patents yet.

Viernes

DavecUK That’s not actually true, Antonio holds neither patent. M&V SRL (Paolos Company) owns the Patent for the Vostok and is the company that owns the sub brands Elcor and ACS. For the Vesuvius it is a similar situation.
