Cooler/Chiller Question

[TTRJohn]

Would this be a good choice for a chiller:

Oceanic Systems | Products | Aquarium Chiller

1/2 HP model Or 1 HP?

For a 30 Gal anodizing system (sulf/acid bath) ~24" X 18" X 18" tank

Also, if so, do you draw the acid water through the chiller? Or do you make the chiller a closed loop system?

I was also going to use a heater & controller for USplastics so I can maintain a ~70 degree bath at ALL times...

No one?

A 1/2 hp will work for a 30 gal. tank. The electrolyte will need to be pumped through the chiller.

So it is safe for LONG term use to pump the acid solution through this chiller? Is this the best chiller out there? Recommendations?

Also does anyone know of a smaller closed loop system with a titanuim heat sink for the transfer? Something at or less than $2,000... I want to hold a very close temp for accuracy...

If you run your tank at LCD anodizing acid ratio, yes. I have been running mine for over two years now. The majority of salt water aquarium chillers do not have many differences between them. The main concern is that it has a Ti heat exchanger. As far as that particular brand of chiller, I cannot say. I can find a link to the brand I currently use.

Here is an old post from when I got my chiller. I got the SubZero model in the lower link. They have made changes to their product lines. The one I got is a 1/4hp run on a 60 gallon tank. It took a while to get down to temp but holds it alright. If ambient temp gets too high 85+, it is borderline on being big enough.

How do you use the CL-650 Chiller?

Did you get your question answered?

I am running about the same size tank as you and I went with a 1/2 hp.
