Abstract
A temperature-controlled case is provided including a frame and a door coupled to the frame and pivotable about a pivot axis between a closed position and an open position. The door includes a passage that interchangeably receives a door closure control assembly at one of the top or the bottom of the door, and an electrical connectivity system at the other of the top or the bottom of the door. The electrical connectivity system includes a first electrical connector coupled to the door, and a second electrical connector coupled to the frame so that the first and second electrical connectors are engaged when the door is coupled to the frame. The door closure control assembly includes a torsion spring that is fixed at one end to the door and fixed at another end to the frame, so that when the door is opened the torsion spring provides an increasing force to urge the door toward the closed position.
