I have a used 3 tap tower. It is air cooled not glycol. It comes with shanks, elbows and faucets. All you need to do to usebit isninstall your lines and handles. The faucets are the traditional style not perlicks. It is used and shows some wear but is inngood shape and it was in service until this morning when I installed a new 5 tap tower. 100 plus shipping.
