A still further object is the provision of a beer drawing and cooling system designed to convey beer or similar beverages from the keg to the dispensing spigot, and cool it at the same time.
The beer drawing and cooling system shown and described in this application has been designed so as to form as simple and compact a unit as possible, the entire system being self contained, with of course the exception of a refrigerant compressor which can be readily positioned along side of the unit when in operation. The unit has been designed to cool and dispense beer or similar beverages from one or more kegs as desired, and is particularly adapted for multiple keg installations utilizing kegs of the kind described above.
