Claim 14:
15. A dual redundant cooling system for a container, comprising:
a first cooling unit positioned in a first cabinet attached to the container, the first cooling unit having a first controller operating a first cooling loop to cool an interior of the container;
a second cooling unit positioned in a second cabinet attached to the container and adjacent the first cabinet, the second cooling unit having a second controller operating a second cooling loop to cool the interior of the container, the first controller and the second controller communicate a switch signal between each other so that either the first cooling unit is a primary cooling unit operating the first cooling loop or the second cooling unit is the primary cooling unit operating the second cooling loop, wherein the first controller or the second controller of the primary cooling unit controls the first cooling loop or the second cooling loop to cool the interior of the container to a predetermined set point temperature; and
a system interface box connected to the first cooling unit and the second cooling unit, the system interface box having a first user interface connected to the first controller of the first cooling unit and a second user interface connected to the second controller of the second cooling unit;
wherein the first controller or the second controller of the primary cooling unit operates the first cooling loop or the second cooling loop for a longer of a preset time period and when the temperature of the return air reaches the predetermined set point temperature.
