A commercial refrigerated display case includes mullions for slideably receiving removable ballast drawers from the sides of the mullions for quickly and easily servicing fluorescent ballasts.

Refrigerated display cabinets with improved mullion assembly

A commercial refrigerator cabinet is illuminated by fluorescent lamps which are located closely behind insulated glass doors for closing the cabinet. Each lamp is located behind a reflector and is at least partially enclosed by a clear plastic lens having multiple facets on its inner side. The reflector and the lens cause the light emitted from the lamp to reflect and refract in such a manner as to distribute the light substantially uniformly on products located at various distances from the lamp and to reduce glare in the immediate vicinity of the lamp.

Lighting system for commercial refrigerator doors

A refrigerator door assembly having a door mounting cabinet frame which has a thermally efficient composite design comprising a non-metallic pultrusion-formed structural frame member and an outer metallic trim panel mountable on the structural frame member for providing the desired finished appearance, which may be made consistent with conventional commercial refrigerator and freezer door assemblies. The door mounting frame includes a mullion which also includes a pultrusion formed non-metallic structural element. A rigid plastic molding assembly encompasses the rear and sides of the structural frame members and define air insulating spaces about the frame members. The pultrusion formed frame members permit thermal insulated mounting of metallic accessories by ultrasonic welding methods.
