This 12 tap kegerator was used roughly 3 years. It works fine and has all gas lines, product lines (although I’d replace the product lines), and two gas manifolds mounted on the back interior wall. It has the tubes that stick up into the towers for cooling. I built mine into a line of cabinetry at one of my locations as you can see in the pictures. It was a good alternative to a cold room, glycol run, etc. Beverage-Air DD94HC-1-B-ALT-12T is the model number. I have it priced to sell.
