1.Energy saving, 2.Dehumidify and dryer, 3.Dew point up to -40C, 4.Sweden honeycomb rotor, 5.Fault less, easy to operate - details see: https://www.machineto.com/600kg-low-dew-point-honeycomb-rotor-dehumidifying-dryer-for-pet-material-drying-10335931

1. Application:

GDD series dehumidifying dryers combine dehumidifying and drying systems into a single unit. They have many applications in processing plastic materials, such as PA, PC, PBT, PET etc. All models feature GD-H honeycomb dehumidifiers with built-in process heater and insulated drying hopper. Under ideal conditions, it can provide dehumidified dry air with a dew-point lower than -40°C.

2. Features:

Standard configuration:
1)The GDD dehumidifying dryers use honeycomb dehumidifiers.
2)Each model combines dehumidifying and drying functions into a single unit.
3)Insulated drying hopper features dry air down-blowing and cyclone exhaustdesign. This improves drying efficiency and reduces energy consumptionwhile maintain a steady drying effect.
4)The dehumidifying section of the GDD series features two coolers to ensure alow return air temperature and low dew-point.
5)Compact in size for ease of movement and space saving.
6)Microprocessor is the standard equipment.

Accessory option:

1)Dew-point monitor is available as option.
2)Suction box and hopper loader are optional for conveying material conveniently.
3)PLC control plus LCD touch screen is optional for convenient centralized control.

3. Working Principle

Dehumidifying: damp and hot air from dry material barrel is blown into rotor after cooled. Moisture from the air is absorbed by rotor and is then adsorbed by
regeneration heating air. Two strands of airflow function on the rotor. And with
the rotation, moisture from the air is absorbed and expelled after absorbed
regeneration air to form stable low dew-point air, which is dried to the drying
temperature and then is blown into material barrel to closed circle to dry material.
