Redundant humidity control mechanisms are provided for electronic systems which are cooled to temperatures below the dew point temperature of the ambient environment in which the systems are present. In particular, system environment is controlled in an overall fashion by providing a thermally insulating and substantially sealed enclosure for containing both air coolable and refrigerant coolable components. Humidity control and cooling are both provided in a redundant fashion to ensure reliability of service and availability of the components which are being cooled. Both desiccant-based and refrigeration-based humidity control mechanisms are provided. The present invention also includes embodiments in which multiple heat exchange fluids are employed.
