A small refrigerator maintains a container of ice that can be used to cool a data processor in an emergency. If the customer's chilled water supply or its heat exchanger fails, the processor cooling loop is switched to pass through the ice. During this emergency operation, the flow of water through the ice is controlled to maintain the desired temperature for water entering the processor. The ice container is thermally insulated, and during normal operation of the processor the refrigeration unit runs only intermittently. An ice sensor is located in the ice container to turn off the refrigerator to prevent the ice from freezing solid and to thereby maintain a water passage through the ice.
