A tap system used to dispense homebrew. It consists of a cooler full of icewater (more ice that water) with copper tubing inside. Inlet tubes and outlet tubes are connected to the copper and allows flow of beer from the keg to the tap going through the copper. The copper acts as a heat exchanger in its ice bath, and cools the beer on its way to dispensation. This will dispense cold beer from warm kegs, and is a must anywhere that you cannot keep your kegs iced down.
