Jason,
 
We've two different vintage Kiel III's.  The older one has a Waldkircher
type E2 E1K1.B oven fan motor and the "newer" one has a Waldkircher-Dreger
type E2C (can't find anything on it that resembles the E1K1.B script).  They
look identical and have the same power ratings(220V 50Hz, 2900 1/min, 2 µf,
.025 kW, COS .8, .42A) - though the power electronics are re-arranged a bit.
We've not had to replace either of them just yet (recently lubed the newer
one) so no help on what to order as a replacement.  They seem very sturdy.
The Thermo part number for the kiel III oven "fan" is 003 0440.  Could you
email me (directly if need be) in regard to the bearing replacement?  Some
preventative maint. might be a good thing about now.  Good luck.
 
Andy

Hi All, 
The fan motor in my Kiel III (1998 vintage) just failed last night.  The
bearings were getting loud late last week and I was scheduled to replace the
bearings this morning - I should have done it on Saturday instead of trying
to push through a few more "vital" samples!  I had even set out all the
tools and the new bearings set out and ready on Friday.

Back in 2002 I had some fan issues with the same Kiel and Rindy from WHOI
sent me the part numbers for the fan in her Kiel.  But the strangeness is
that the fan in my Kiel is completely different compared with the one in
hers.  Here is the story:

My Kiel has a motor mounted outside the Kiel oven inside a cover on the back
of the Kiel.  The motor shaft runs through the back of the oven box and
there is a fan on the long shaft mounted directly behind the heater coils.
It was made by a company in Germany - Waldkircher, part number E1K1.B  I
can't find anything on the web for this company.  The motor is something
like 12 cm in diameter by 12 cm thick, shaped like a cylinder

The fans that Rindy provided information on look like a square fan from the
back of a computer.  They are different sizes.  One is PAPST model 4550N,
230V, 11.7 by 11.7 cm.  The other is COMAIR Rotron model SU3B1, 230v, 8 by 8
cm.

So, my questions to the list are:   Is the fan in my Kiel different from
others?  Does anyone have a part number for replacement of one like mine?
What type of fans do other people have in their kiel?


If Rindy and I were communicating correctly then I will probably just try
retrofitting my Kiel with one like she told me about.  My first assumption
is that I would mount the fan on standoffs maybe even using the mounting
holes that the original fan used.


Thanks for any help on this somewhat smelly (due to burned insulation)
Monday morning!  Jason
