Wonding about tower cooling going from a single tower to larger dual tower. The current kegerator pass-through hole is 1 and 5/8 inch diameter. The dual faucet Micromatic tower I want to add is 3 inch diameter. Concern is the opening size and if it will be adquate to keep the 3 inch tower and beer lines cold enough to perserve the beer properly. The two lines will fit through the hole but there will not be much excess space. There currently is no fan inside the kegerator. It will be a pain to widen the hole.
Anyone upgraded a tower like this?
Did the smaller hole opening workout okay?
