A refrigerated showcase has a front opening through which a consumer can view and access foodstuffs on display. The foodstuffs are cooled by coolant air introduced through a rear wall of the showcase. An air curtain directed downwardly at the front opening minimizes coolant air loss through the opening. Dual evaporator coils are arranged in housings on different sides of a plurality of fan motors. Condensate water produced by the dual evaporator coils is pumped to a primary dissipater pan arranged on top of the showcase. Because of the large amount of condensate water produced by the dual evaporator coils, a secondary dissipater pan is provided as a back-up system for any excess condensate water. A three-way solenoid valve diverts the excess condensate water to the secondary dissipater pan when the primary dissipater pan is full.
