Abstract: An improved point-of-sale product chiller that is modular in design and construction whereby the server may be readily produced in various sizes and capacities for point-of-sale display and sale of chilled products. An insulated enclosure includes a base panel, a pair of sidewall panels, and a plurality of modular end wall panels that form a chilled product cavity. The panels are formed of hollow, blow-molded thermoplastic with foam insulation panels inserted therein. A chiller of a desired size is produced by selecting a base panel of the desired size and assembling to it modular end wall panels and sidewall panels of the desired size. One or more insulated central divider panels may be assembled within the enclosure to form multiple chilled product cavities within the enclosure. Removable, flat cold cell panels having cooperating edges are inserted about the inner periphery of the enclosure to maintain product temperatures inside the cavities.
