Re: High tech gadget?
First I'd like to correct a mistake I made in my previous post: Bob
Goeman's review of the IceProbe is in the *May* issue of FAMA, not the
April issue as I had stated.
Also, I failed to mention that the IceProbe has an optional controller
available that costs around $49 USD.
>>Robert asked: "Are there any other important specifications not listed
here that should be considered when choosing a chiller?"
Cavan stated: "The main thing about the Iceprobe is that you can get it
for $100 and that's WAY cheaper than any other chiller."<<
The cooling capacity of a chiller as it relates to the size of the tank(s)
you want to cool is very important. This is where the IceProbe can lose
its cost advantage over traditional chillers.
The IceProbe will cool 10 gallons about 6 degrees F below ambient, 20
gallons about 3 degrees F, and 40 gallons about 1.5 degrees F. Get the
idea? As Scott pointed out, it would take a sizeable array of them to cool
a large tank much. However, an array of IceProbes would take up less room,
not require plumbing (other than drilling the holes for the bulkhead
fittings), and they are relatively energy efficient compared to a
compressor. Goeman did state that the IceProbe would cool a
"fully-insulated" 10 gallon tank 20 degrees F below ambient, so the actual
performance of the unit can be tweaked some.
The IceProbe is designed/used for everything from organ transport to
homebrewing and not just aquaria. Since the Azoo product is likely
designed specifically with aquaria in mind, it may prove to be a more
desirable product. I share the feeling that it won't be cheap, though.
In the end, it really depends on just how much cooling you want/need as to
which type of chiller is "best".
>>Robert: "The fact that this unit heats water as well
as dropping the temp sounded interesting."<<
Simply reversing the polarity of the power supply will switch the
thermoelectric unit from a cooler to a heater. Conventional chillers will
heat, too. For now, I think I'll stick with my Ebo-Jagers for heating. :)
