This is a picnic cooler/ice chest converted to a beer dispenser using either a cold plate or a stainless steel coil to chill the beer. If using a cold plate, the plate should be tilted, and the box should be continuously drained of water. If using a coil, a mixture of ice and water must completely cover the coils in the cooler. In either case, beer should be run through the system prior to adding the ice to prevent a freeze up inside the coil. Cubed ice should be used in this type of box, and the CO2 regulator should be set between 30 and 40 lbs of applied pressure.
