Application of PET Crystallizing Drying Machine

OTD Dual-tower Desiccant Dehumidifiers are mainly used to dry hygroscopic engineering plastics or regrind materials. Under ideal conditions, the dew-point of dehumidified dry air can be lower than -70^oC, the largest of which can provide dry air up to a quantity of 3,800 m³/hr.

Application Cases of PET Crystallizing Drying Machine

OTD Twin-tower desiccant dehumidifiers features in lowest dew point with the driest air to achieve the best drying effect for hygroscopic plastic resins, like PET. It can achieve the lowest dew point of less than -70 degrees, but it consumes more energy than the honeycomb rotor dehumidifier to get a similar drying effect. It is suitable for the plastic process which needs fast-drying and have good value-added products.

Notes for Installation and Positioning:

1) Machine just can be mounted in vertical position. Make sure there’s no pipe, fixed structure or other objects above the installing location and around the machine which may block machine’s installation, hit objects or injure human person.

2) In order to maintain convenient operation, it’s suggested to keep 1m space around the machine. Please keep at least 2m distance between the device and the inflammable goods.

3) This series of models only could be applied in working environment with good ventilation.
