01Trace the heat and moisture
An aftercooler reduces compressed-air temperature so moisture can condense and be separated before later treatment. If the outlet becomes warmer, the dryer may face a different moisture and thermal duty. Nameplate flow alone does not describe that change.
02Compare meaningful temperatures
Record compressor discharge conditions, aftercooler outlet temperature and the cooling-air or cooling-water condition at the same time. Compare similar loads rather than an idle morning with a hot production afternoon. Note any loss of drainage or cooling performance.
03Use the trend for action
If the temperature gap changes under comparable conditions, arrange the manufacturer's prescribed inspection of cooling surfaces, flow and controls. Confirm dryer performance after the cooling issue is corrected. Increasing drying capacity should not be the first answer to an unresolved upstream cooling fault.
