Why is there water in my Deltech Dehumidifier compressed-air system?
- S
  Sandra CamposAug 7, 2025
  If there's water in your Deltech Dehumidifier's compressed-air system, it could be due to condensate residues from before the dryer started. Try blowing out the compressed-air system with dry air until no more moisture comes out. If possible, open the collection point at the most remote location. Alternatively, the bypass may be open, in which case you should close it. It's also possible that condensate from the prefilter isn't being separated, requiring a check and repair by trained staff if necessary. Finally, the operating parameters might have changed since the dryer was installed; correct them to the original design parameters.

Why does my Deltech SPX Flow DSHD have a high pressure loss?
- D
  Daniel WilkersonAug 13, 2025
  A high-pressure loss in your Deltech Dehumidifier might occur because the pre- or after-filter cartridge is overloaded. Replace the filter cartridge. It could also be because the operating parameters have changed since the desiccant dryer was installed. Restore the operating conditions for which the dryer was designed.

What to do if my Deltech SPX Flow DSHD displays a 204 error?
- A
  andreaperezAug 19, 2025
  If the Deltech Dehumidifier displays error code 204 (LED Warning/ Service/ Alarm flashes red), which indicates a PDP Alarm, it could be due to several reasons. The desiccant dryer may have only been switched on briefly; in this case, operate it for a while with a low load. Alternatively, the desiccant dryer may be overloaded; adapt the operating conditions to the permitted parameters. Finally, the PDP sensor itself might be defective; check the PDP sensor and replace it if needed.
