For customers who make PET preform or PET bottles, it’s quite important to do proper PET resin drying first and to remove the moisture from inside.
Some customers only use hopper dryer for PET drying, but it’s far from enough. Based on our deep experience in this industry, we strongly suggest that for small unit, it’s better to use all-in-one dehumidifying dryer and for large unit, it’s better to use insulated hopper dryer which can reach drying temperature up to 180℃， and together with a honeycomb wheel dehumidifier which helps to remove the moisture from inside the PET resin.
And when you select the PET drying and dehumidifying unit, pay attention to the following details: drying temperature, dew point and moisture content after drying.
