I've built a gylcol chiller out of an old dehumidifier. It's currently set up to chill a glycol/water bath in a cooler.
I'm having trouble finding a suitable pump to pump the solution through my conical's internal stainless coils. I'm currently using a ~300 GPH fountain pump, but it doesn't quite have the power to lift the solution through the chiller when it's empty. Once it get's going, it stays going, but it takes some care and feeding which I'd like to avoid.
So my question is, do people normally circulate the glycol solution from the reservoir (cooler) through the chiller, or should I use a copper heat exchanger in the reservoir and pump within a totally closed loop?
Either way, it gets kind of tricky to disconnect the chiller and clean it. Not sure how to deal with that, since I would be breaking the loop...
Thanks
