A refrigerated cold beverage merchandiser ( 10 ) includes an enclosure defining an insulated, refrigerated display cabinet ( 25 ) and a compartment ( 30 ) heat insulated therefrom wherein a compressor ( 40 ) a condenser ( 50 ) and a condenser fan ( 60 ) are disposed. The condenser ( 50 ) is formed by a plurality of in-line tube banks ( 52 ). Each tube bank ( 52 ) is a serpentine tube formed a plurality of unfinned, straight tube segments ( 54 ) extending in parallel rows ( 55 ) between a pair of spaced, opposed end plates ( 58 ) and elbow turns ( 56 ) connecting neighboring straight tube segments ( 56 ) in a conventional manner. Each successive tube bank ( 52 ) is arranged with the other tube banks so that respective parallel tube rows ( 55 ) are disposed in-line from the front to the rear of the condenser ( 50 ) or with each successive tube bank being offset in a slightly staggered arrangement.
