There are 2-3 options for kegging. have a look thru this thread -
LinkyThe most common would be those who build kegerators. That is, the fridge/freezer holds the kegs and taps come out the front.
The 2nd option is the one i have and that is a regular font on a beer with lines running from a fridge.
These 2 options rely on you being able to store the beer in a fridge/freezer.
There is a 3rd option and that is a temprite. Beer is stored in kegs at room temperature and as run thru a temprite (heat exchanger) and then out thru a tap.
