A temperature controlled case includes a housing that defines a temperature controlled space and a multi-circuit cooling element in thermal communication with the temperature controlled space. The multi-circuit cooling element includes two or more cooling coils. Each of the cooling coils is coupled to a different circuit structured to selectively circulate coolant through the multi-circuit cooling element. Each circuit is fluidly separate from each remaining circuit such that the coolant circulated through each circuit is not shared with each remaining circuit. The multi-circuit cooling element further includes a plurality of heat exchange fins coupled to each of the two or more cooling coils such that each of the heat exchange fins facilitates heat removal from the temperature controlled space by each of the two or more cooling coils.
