The display portion has a plurality of shelves that are accessible through an opening in the front of the display portion. Access to the shelves also can be obtained from the rear storage portion of the system. A cooling unit is provided that includes a fan and two sets of refrigerating coils. The cooling unit provides refrigerated air from one set of coils to an air conduit for establishing a primary air curtain across the front of the display portion. The refrigerated air from the other set of coils is supplied to an air conduit which in turn supplies the air to the storage portion. A second air curtain is also provided across the front of the display portion; this secondary air curtain extends along a path positioned towards the outside of the display portion with respect to the primary air curtain. A return path for the air from the primary and secondary air curtain is provided along the bottom of the display portion.
