Doug,The glycol temp needs to be about 28 deg. to be able to maintain 38 deg. at the faucet. At 38, your glycol would be returning to the cooler at about 48, thus warming your beer, causing major foaming issues. An idea that I had,was to run the glycol thru a coil box full of lots of ice before running back to the faucets, but still, you would not be at 28,may be 34 and you would constantly be replenishing your ice supply. Never got the chance to try it. It probably would not work anyway Good luck, Tapman
