Not if it is a true co2 unit. A 20 pounder will take a 6 pack down to about 40 degrees on an 80 plus day without a fuss. BTDT with units we were taking out of service. Of course it was soda but hey it did the job. I wouldn't use it as the method of choice though since that can get VERY expensive real quick.

That worked well, too! :-)
