PETG dryer dew point too high, insufficient drying
Fenómeno del problema
The dehumidifying dryer dew point is too high (>-30°C), drying is insufficient.
Análisis de la causa
The desiccant (molecular sieve) is ineffective or saturated, the regeneration system is faulty, and dew point detection is inaccurate.
Solución
Check and replace the desiccant; repair the regeneration system; ensure dew point ≤-40°C.
Conclusión clave
PETG drying effect depends on the dew point; dryer maintenance cannot be ignored.
