Refrigerated merchandiser with foul-resistant condenser

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