What to do if SPX Pneumatic Products IBP Dehumidifier shows a High Humidity Alarm?
- A
  Anthony MorganAug 18, 2025
  To troubleshoot a High Humidity Alarm on the SPX Dehumidifier, consider these potential causes: * The desiccant bed may be overloaded. Check the inlet air flow rate, temperature, and pressure. If the flow and temperature are higher than the design specifications, or the pressure is lower, it can overload the dryer. * The dew point sensor or monitor could be damaged or defective. Inspect the sensor for any physical damage and verify the operation of the monitor/sensor. Replace if necessary. * There may be a loss of desiccant drying capacity. Check the filter elements and drains for contamination due to improperly filtered inlet air. Repair or replace as necessary. Also, consider if the desiccant's useful life has been exceeded.
