• wherein the double return flange comprises a front section, a back section, and an inner section extending from the front section to the back section such that the front section and the back section both extend outward from the inner section;
• wherein the channel further comprises first and second interior legs extending outward from the inner section to define a heating element duct.

A refrigerated cabinet comprising:

• a cabinet body defining an interior and having a door frame defining a doorway for providing access to the interior from an exterior of the refrigerated cabinet, the cabinet body comprising:
• a wrapper having a front edge margin adjacent the doorway;
• a liner having a front edge margin adjacent the doorway;
• and
• a thermal breaker having an outer interface connected to the front edge margin of the wrapper and an inner interface connected to the front edge margin of the liner whereby the thermal breaker connects the front edge margin of the wrapper to the front edge margin of the liner and provides a thermal break between the front edge margin of the wrapper and the front edge margin of the liner;
• and
• a door connected to the cabinet body for movement in relation to the cabinet body between an opened position and a closed position, the door comprising a gasket configured to seal against the door frame in the closed position, the gasket comprising an inner sealing element and an outer sealing element, the inner sealing element configured to seal against the thermal breaker and the outer sealing element configured to seal against the front edge margin of the wrapper when the door is in the closed position;
• the refrigerated cabinet further comprising a refrigeration system configured to maintain a −10° F. (−23° C.) set point in the interior of the cabinet body, the refrigerated cabinet configured to prevent condensation from forming at the door frame when the refrigeration system maintains the −10° F. (−23° C.) set point in ambient conditions of at least 90° F. (32° C.) and at least 70% relative humidity without heating the door frame.

A refrigerated cabinet comprising:

• a cabinet body defining an interior and having a door frame defining a doorway for providing access to the interior from an exterior of the refrigerated cabinet, the cabinet body comprising:
• a wrapper having a front edge margin adjacent the doorway;
• a liner having a front edge margin adjacent the doorway;
• and
• a thermal breaker having an outer interface connected to the front edge margin of the wrapper and an inner interface connected to the front edge margin of the liner whereby the thermal breaker connects the front edge margin of the wrapper to the front edge margin of the liner and provides a thermal break between the front edge margin of the wrapper and the front edge margin of the liner;
• and
