Topic: EU Offices Scrap Espresso Machines After Tests Show (4 msgs / 136 lines)
1) From: Steven Van Dyke
Saw this news story this afternoon.http://www.foxnews.com/story/0,2933,461884,00.htmlThey're scrapping a whole slew of Cimbali's just =
because of a little nickel and lead in the cup!
Heck, I'd think poisoning top bureaucrats would be a bonus feature!
"
The coffee served in the private offices of =
European Commissioners tasted decidedly odd, even =
though the espresso machines cost more than $7,500 each.
The metallic tang was too much for one official, =
who sent samples from his machine back to his =
native Austria for testing ­ only to receive =
results suggesting that the European Union’s most =
senior figures were being slowly poisoned.
Now the Commission’s entire collection of elegant =
Cimbali coffee-makers, together worth $153,500, =
have been mothballed while the Italian company ­ =
which disputes the findings ­ carries out its own analysis

Hmmmm.......the stories didn't say what in the machines was causing  =
the high nickel and lead levels.  But I do remember my old espresso  =
repair tech (yeah, the one who stopped returning my calls) telling me  =
he was severing ties with Pasquini because of nickel flaking off the  =
boilers.  Maybe Bezzera is providing the boilers to Cimbali as well.

What is the matter with staying with high grade stainless? I'm sure I don't
know enough to comment on this in depth but there is a reason why LM's and
many other machines don't have this problem. I do have a two year degree in
welding technology but the class on building espresso machines what a wee
bit lacking. :^)
How bout it Ray O. Any thoughts on this?

Indeed-
My coffee pot boiler will have a flanged s/s cylindrical can. All boiler
electrical and plumbing devices and connections are on a flat disc with an
o-ring seal groove and fasteners. The disc bolts to the flanged can.
If lead ions can be detected in the effluent brew, there has to be Tin/ Lead
solder in use somewhere in the plumbing line or machine assembly, in contact
with the water.
Espresso machine production seems to start life as prototypes that get the
skin applied several weeks after a frame is built and hacked out to mount
the different components. Pumps, solenoids, tanks, plumbing designs and
changes all get stuffed in, hacked out, changed, and spliced back in.
European standard has been to get a few prototypes working, wrap one up and
put it in shipping and set the others as production mock ups. Customer is
beta tester for longevity, even for the insane FOMOCO-like production
changes. "Bring the old part," ad infinitum.
While THHN or THWN wiring doesn't care about boiling water temperatures,
electric connectors and controls are pretty narrow-minded about their
environment.
It's a marketing point to be able to set cups on top of the machine to heat
them. Ignorance of the problem of heat degradation in electrical connections
and devices doesn't help the customer.
For a machine spec'd to work at 2550w max at 220v, the current draw is 11.6
amperes. A 115v, 20 ampere circuit can supply 2300 watts. The machine has to
give up some performance, because there is a 250 watt shortage at 115/ 20.
Maybe it works after everything is hot, and the duty cycle is low. For $2
Grand, cut corners? Pferdescheiße!
Cheers, Mabuhay and Magandang Hapon -RayO, aka Opa!
The grinder is the primary implement!
