  • Page 11: Initial Considerations

    The driest dew/frost point temperature the MG-101 can produce is the dew/frost point temperature of the dry nitrogen source plus 25°C (45°F). If dry nitrogen of this quality is not available, please contact GE Sensing for assistance. The wettest dew/frost point temperature that can be generated is determined by the ambient temperature, and it must be at least 10°C (18°F) below the ambient temperature.
