Abstract: A gasket for a door of a refrigerated cabinet has a bellows chamber extending backward from a base connected to a door. A magnet chamber is supported on the bellows chamber, and a cantilevered arm extends from the inner side of the magnet chamber. The cantilevered arm includes a proximal middle chamber, a distal sealing bulb chamber, and a partition wall between the middle chamber and the sealing bulb chamber. A condensation shield is outward of an outer bellows chamber wall and extends from the base to the magnet chamber. An inner support chamber is received between the bellows chamber and a profiled section of the door. A wiper extends forward from the inner support chamber. The sealing bulb chamber is configured to be pressed backward against the wiper such that the gasket defines a supplemental chamber when the door is closed.

Abstract: A refrigerated cabinet is equipped with a thermal breaker between the cabinet liner and wrapper. The cabinet can operate at the −10° F. (−23° C.) set point in ambient conditions of at least 90° F. (32° C.) and at least 70% relative humidity without door frame condensation. A cabinet door gasket can have an inner sealing element that seals against the thermal breaker and an outer sealing element that seals seal against the wrapper. The wrapper can have a double return flange nested in an outer interface of the thermal breaker. The thermal breaker can hold a door frame heater inboard of a magnetic contact region with the door gasket. The frame heater can be located so that only plastic material is directly in front of the frame heater. Corner joiner elements can be ultrasonically welded to the thermal breaker to join four thermal breaker pieces together at mitered joints.
