A refrigerated merchandising cabinet is presented including an upright insulated housing having an interior which forms a cold storage chamber. The housing is open-fronted having a front access opening closed by a plurality of juxtaposed hinged access doors. An interior of the cold storage chamber is sub-divided into three separate cooling compartments by two upstanding internal divider panels. Three refrigeration modules are mounted in a row on top of the housing and are operable to circulate chilling air in a controlled manner through the cold storage chamber for chilling or freezing product for sale stored within the cold storage chamber. Each refrigeration module is associated with one of the cooling compartments and operates independently of the other refrigeration modules in response to sensed climate conditions within the associated cooling compartment.
