The question would be how to maintain cold water at the reservoir to cool the radiator water during the transferring as the titanium as insulator itself.

I was thinking of placing these radiator in a pail or styrofoam box of cold water.

periodly put ice blocks in the sump?

My work place has a few coldroom that can chill to -5 deg celsius. Going to make a few bottle of pykrete and see how long it can chill the water reservoir. Need to purchase a few of that radiator and find some sawdust, a pail full worth, to start that project. The sawdust is tough for me to locate as I do not have transportation and with my slip disc condition, can't walk far and carry stuff.Originally Posted by Land2013

i think there is no point if you chilling to only 26 degree. just get a 2nd hand chiller will do the job. you can spent more time looking at your tank than changing the ice block.

Totally agree with this. A properly matched chiller can be quite efficient. The plus point being you don't have to worry about temperature spikes with the diy situation affecting your fauna.
Did some browsing and found it could work if using peltier TEM mount with heat sink (with fan) on this radiator however it could come with >40watt by doing so. How do you guys feel?
no point too. all you have found or wanted to do, i have already do before. hehehe

lets say TEM is running 24/7.
total wattage used will be 40 watt X 24hours X 30days = 28.8kW per mth
as for chiller. efficient rate is 1/4 kick in, 3/4 rest.
lets take 150w chiller.
(150 X 1/4) X 24 X 30 = 27kW per mth
just do the simple maths calculation yourself.

How big is your tank? TEMs are mainly effective for small tanks. Even then they are good to bring down the temp by a few degrees only. Your other issue would be how to mount the TEM for it to function effectively.
It was 2" tank.
Think you are better off looking for a second hand chiller. Can try looking for a Haelia hc 100a. http://www.hailea.com/e-hailea/product1/hc-100a.htm. It's one ov the smaller chillers around.
I've never found TEMs to be more efficient than compressor based chillers unless you have a very small tank, so even the smallest chiller is grossly oversized.
you mean 2 feet right? cannot be 2 inches hor?

Oops! It's 2ft.

I won't resort to TEM chiller, I have 1, it didn't perform to my expectation. I do have a spare 1/10hp chiller but with a aircon compressor chiller running my 4 ft marine tank, activating the 1/10hp chiller would increase my electrical consumption.
Using the amenities at my workplace to freeze the pykrete solution is a method I am looking at. I am not doing it alone, I have a colleague who would be going the pykrete path except that he is not using the titanium radiator.

hello there,
confirm inside titanium? got other sizes, please share with me details.
BFG, i went "what the hell!! -5 deg.." till i read workplace cold room

Are you bully newcomer? I already explain why write the $ in that way in the very first page to explain.
Relax, don't take it too personal, we're all here to share. Welcome to the forums, generally people here are helpful and friendly, sometimes because we are passionate, the discussion can become heated.
Personally I think it'll take a very big radiator, to bring the water down to room temperature at best, to do anything lower than room temperature, you'd have to go with an evaporative setup (which is not very efficient because of Singapore's humidity and it makes your room humid), whereby evaporating water actually can bring the water temperature down to below room temp, TEMs or a chiller.
I don't know how big the titanium radiator in your picture is, but if you could get a hold of a small fridge real cheap, I suppose you could put that into the chiller and run your tank water through that, that should probably guarantee some measure of success.
