Thanks for the quick response sswee. The chiller I'm looking at is on the Caswell site:
http://www.caswellplating.com/kits/heatchill.html From what you said, it looks like I would need an external pump to circulate the acid.
Your setup is very cool, thanks for directing me to the pictures. If I'm looking at the pictures correctly, it looks like there is a drain at the bottom of your tank that feeds the inlet of the pump. Then, the outlet of the pump goes through the pvc pipe back into the tank and is dispersed through small holes in the pvc. Is that correct?
I would be interested in purchasing the pump that you have, can you direct me to where you purchased it? Also, do you worry about the acid eating the pvc pipe and causing leaks? I would hate to have 20 gallons of acid all over my garage floor
.
Thanks again for your help with this,
Craig
