The kegerator holds 2 x 5 gallon cornelius kegs and 2 x 2.5 gallon kegs. It is fed by a 5lb CO2 tank. The top was hand built from red oak and the drip tray was built from laser cut acrylic. The kegerator has 4 temperature sensors to monitor temperature in the kegerator and the draft tower. The CO2 tank and each keg is monitored by modified scales to keep an eye on liquid levels. The taps are stainless steel in order to sever anything from beer to soda.
