Dear all,
We are facing high dew point issue in instrument air.
Due to high dew point we changed desiccant which was four years old. Desiccant is air regenerated type 4mm size. following items are checked to find out root cause.
1) prefilter of desiccant
2) compressor side filters & moisture traps.
3) Regeneration cycle of 4 minutes.
Still with new desiccant we are facing high dew point issue. After replacing of desiccant only one day dew point was -35 deg. C. after that it drops to -5 deg. C.
If anyone have more information or anything to be check please share.
Thanks & Regards,
