Copper from a chiller? Need Titanium Radiator?

[funman1]

Well That mystery chiller I got seems it's not made for saltwater at all..
It was turning the water in the bucket light blue, so I wondered since dissolved copper is blue.

I got a hold of a copper test kit and the water in the bucket was reading at the top of the scale for copper, and it could have been off the scale?

So now I know I can't use this on my reef tank, Thank heavens I didn't ever put it in contact with tank water yet!!

So here's what I need to fix it (I think, I want to hear your ideas too)

I want to make a closed loop for the chiller and fill it with antifreeze or something, then somewhere find a titanium radiator or something that I could run in the closed loop with the chiller.
Then drop that titanium radiator in my sump.

Good idea, bad idea?
Also I would need to find a tiny EXTERNAL water pump.

Do you guys know where I could find either of these two items to make the chiller work with saltwater?

Thanks in advance..
Here's some pics of the chiller and the water..

if u can't find a titanium radiator, you can use Ti tubing and bend them into a lot of loops, run antifreeze through it and make the Ti loop as a drop-in for the tank. beware not all Ti are corrosion resistant against salt water, be sure to check the grade before you purchase it.

or you can open the chiller up to see if you can replace the copper tubing with titanium ones. good luck.

The way the chiller is built, it's impossible to tear it apart and change it out.


Where would I find Ti Tubing?
Any recs on a small external pump?

Here is the problem....by the time you buy the materials and fab it up, you still won't have a reliable, overly efficient system, and its not so much the tubing....what about fittings, you could have $20 in one fitting. Bending it? Never worked with it, who knows if it will handle the stress of a steel jawed tubing bender.......I would try a Via Aqua Polar Bear, pretty good and cheaper.


try McMaster for the pump or Grainger......

That sucks Steve... the guy who sold you that thing should be taken out and shot. Outrageous!

What your looking for is called a "heat exchanger".

This model looks fairly cheap in terms of a Ti exchanger goes:

EKE05 Titanium Heat Exchangers by Ericksenâ"žÂ¢, 1/2 hp, 17-25 gpm In Stock $276.00
2+ $262.20

You simply gut that chiller for it's compressor and hook this directly up to the freon. Granted this isn't the cheapest way to go, but it's the professional way to go for sure
