Just  question for those who have built Son of a Chiller rigs... anyone
experimented with using dry ice to power the thing instead of the jugs
of water?  Two advantages I can see are A) cooler temps and B) no
drips.

Would you believe suffocation?

I use a peltier device embedded in the top whose cold surface chills my beer
carboy down to 67 degrees

Re: Son of a Chiller is a S.O.B.


I was considering the same scheme to cool a sankey keg. Was you
thermoelectric device assembled and just need installed? Will you chiller
got down to lagering temps in the low 30's?  Is electronics goldmine on the
web? Did you get the power supply with the peltier device or have to come
with one?

Hi,

What were the specs of your peltier device? i.e. what wattage and
dimensions. Also what voltage are you running it at as my understanding is
that they'll work between 10.8 - 15.6v with their cooling capacity
increasing with voltage.

Re: Son of a Chiller is a S.O.B.


Peltier devices are new to brewing, but are not so new to other avenues of
science.  This is a nice thread to test a market proposal (don't get mad,
just seeing what interest is out there):

A pelitier junction complete with sink and fan (sink is machined to fit a
12" radius (ie. plastic fermenter with gamma seal lid, draws the heat away
from the beer), water-tight seal, powder coated to resist corosion, and
makes it easy to clean.  silicone seal on the outside to ensure positive
seal.  Easy DIY install instructions for plastic primary users (sorry, glass
primary is out of luck, steel primaries are doable, but require special
calculations, since steel is a good conductor of heat.)  Allows for a
disturbance-free liquid temp drop of 10-15 degrees F without adding ice.
Ale fermentation at 78 degrees ambient temperature (~68 degree wort).  Lager
without the box (in development; provides ambient drop of up to 30 degrees).
This is not "drip proof" (yet), so plan ahead and keep it dry.



I'm a nerd, who likes beer (hence the founding of my Brew Club, NLBT (Nerds
Like Beer Too!)).  I've got the plans for the above product lined up, but am
hesitant to go beyond prototyping.  First-run issue (ale temp) worked
fantastically!  Theoretical temp pull-down of 30 degrees is very possible,
just requires a bit more on the outset (I don't like lagers, so I'm not
going to investigate unless I have interest (or at least interest in driking
questionablly aged lagers)).   Temperature sensor to provide real-time
feedback to chiller is possible, although not incorporated into this
iteration.

If anyone is interested in beta testing this device, let me know via this
newsgroup.  I'll contact and see if we can research a new product together.
If you have a different radius primary, let me know, I might be able to
accomodate.

Re: Son of a Chiller is a S.O.B.


Not such a new idea -- there are actually peltier-based aquarium
chillers that have been used this way. I'm pretty sure at least one HB
fermenter manufacturer uses these as a chilling option for their fermenter.

I did some research into it at one time and unless the marketing (supply and
demand) has lowered prices you can buy a 7.0 cu ft freezer for the same
price as a peltier set up. If space is a premium, and you don't want the
freezer or fridge, then maybe. But you would also be fighting the wet
t-shirt that can drop the temp 8-10 degrees with the right conditions.

The questions seem to me to be are you fermenting
lagers or ales and how far on the cold side of the
frost line do you live.

Brewing lagers means (to me at least) having a
freezer.  A Peltier device might be justified for
one or two fermenters, but for more it would
seem a chest freezer with a controller would
be less expensive in the long run.

In the Fall, Winter, and Spring, my basement is
near perfect for fermenting and conditioning ales.

Now if I lived in Yuma, AZ or Darwin, AU, it
would be different.  Without refrigeration, I'd
be SOL.

Cooling capacity increases with voltage to a point but you have to get
rid of
the heat on the hot side or you will be disappointed.
