Brewingshack understands the true spirit of an outdoor party, the portable beer chiller holds 2 different types of beer and keeps them cool and refreshing. You might not need this portable beer chiller if you had the party indoors but, tugging your refrigerator outdoors or even to the beach might seem like an overdo. The double tap beer chiller is lined with 100 feet of stainless steel cooling coils (50ft per compartment). The stainless steel confirms to the 304 standard that is recommended for food. Spring taps shut off the moment you release the pressure, no dripping and wasting the precious beer. Few beer chiller sellers would care to provide the detailed information that we provide, check out the clear images and lucid explanation on the website at http://www.brewingshack.com/jockey-box-dual-tap/
