Why is the dew point high in my ATS Dehumidifier?
- LlopezjohnAug 7, 2025
A high dew point in your ATS Dehumidifier can be caused by several factors. The inlet temperature may be above the design condition, so you should check the aftercooler or compressor. Water might be entering the desiccant bed; in this case, check the air/moisture separator and prefilter, and replace the desiccant if needed. The desiccant could also be contaminated by oil, so install a suitable prefilter and replace the desiccant if necessary. Finally, an insufficient purge rate could be the culprit, so check the muffler.
