Here it is guys. Its a dorm fridge with a 5 gallon bucket of water inside, and 20 feet of copper tubing coiled inside of the bucket of water. The cold water cools the air line so that the water vapor can condense and be caught by the water trap on the outside of the fridge. I've got it connected with quick disconnects so I can move it if I need to. Works great! I haven't had any problems with contamination since I started using it.
