Water Cooled Kegerator Tower?

[Cpt_Kirks]

I always here about glycol cooling, but why hardly ever water cooling for a tower? I know you need glycol if you are going below freezing, but it's not that cold in the kegerator.

It seems a small container of water, with a quiet aquarium pump, would work fine. Just turn the pump on when you are about to have a pint.

Glycol is less efficient than water for heat transfer. But in many applications corrosion, growth, issues also apply.

Why not just let the pump run continuously? It's an aquarium pump so it should be meant for continuous running.

Glycol can go below the freezing point of water and remain a liquid. That's its main appeal. If you are not going that low, than use water and a corrosion inhibitor.

A lot of systems use mostly water and a small amount of glycol. As mentioned above, you'll want a corrosion inhibitor if you're using water. I think most people figure why not use a little glycol as the corrosion inhibitor and get the added benefits of a lower freezing point and better heat transfer?
