Diagram Illustration of an SDR Occurrence
• Figure 23 illustrates a typical SDR trip temperature
(center dotted line) and crystallization sensing detection
sensor temperature (solid).
• The left arrow point indicates where the solid line
crosses the dotted line. This is where the SDR trip
criteria is met and recovery mode is initiated.
• The right arrow point indicates where the SDR
temperature has been reduced to the recovery
temperature (SDR sensor temperature is below the low
temperature solution temperature + 3°F) required for
operation. Operation will be restored after the 11 minute
recovery cycle is complete.
