Solution
Check regeneration filter and clean
and/or replace as necessary.
Reduce the temperature of the cooling
water or increase the flow.
Connect water to the aftercooler/inter-
cooler if not already connected.
Check for adequate water temperature.
Water temperature should be approxi-
mately 85°F {29°C}.
Check amperage of regeneration heaters.
Replace heaters if necessary.
Check all hoses, gaskets, doors, loaders
or other potential areas where leakage
may occur. Replace any defective hoses
or gaskets.
Verify proper drying temperatures and
residence times. If off-gassing is a con-
dition of the material being processed,
contact Conair Parts at (800) 458 1960
for the addition of a volatile trap.
Verify dryer dew point readings with a
calibrated portable dew point meter.
Replace analog option board or sensor.
Dew Point Troubleshooting
Under normal operating conditions, the dryer will produce Dew points in the range
of -40 to -20° F {-40 to -29° C}. However, you may experience situations that pro-
duce undesirable results.
Problem
Dryer not producing
desired dew point.
WARNING:
Any electrical
checks should be performed
by a qualified electrician.
Possible cause
Low regeneration air flow.
Return air temperature exceeds 125°F
{52°C}.
Regeneration temperature is below nor-
mal setting.
Leaks in process lines.
Contaminated desiccant due to off-
gassing, too long of a residence time or
drying temperature is too high for the
grade of material being processed.
Analog option board/sensor malfunction
