So I have a spare Sanke keg that I'm planning to turn into a temperature controlled fermenter. My current plan is to wrap a coil of copper tubing around the keg and circulate chilled glycol through it. I would like to put a bucket of glycol in my chest freezer with a submersible pond/fountain pump which would be controlled by a STC-1000. I might also use some Flex Watt For heat also controlled by the STC-1000. Once I have the kinks worked out, I'll probably wrap the whole shebang in Refletix.
I guess I'd like to know if anyone else has tried something similar. What size pump will I need? Will the glycol be too viscous for a pump designed to handle water? What size and length of copper line will be optimal? I was thinking 50' of 3/8" soft copper, but that might be overkill.
I don't want to turn the chest freezer into a keezer because we actually use it for food storage. Also, this plan would allow independent control of multiple fermenters just by adding an additional pump and STC to subsequent kegs.
Thoughts?
