honeycomb compact dehumidifier dryer

GCD series dehumidifying dryer gathers dehumidification, drying and two-stage conveying three functions, is very suitable for drying engineering plastics materials with hygroscopicity such as PA, PC, PBT, PET. Of them is Optics GCD could be used in processing application of lens, LCD backlight board and discs, it has dew-point of below -40℃under ideal condition.

 It is proved that the hygroscopic materials used in the plastics industry such as PC, PA, PBT, PET, Nylon, etc. cannot be dried effectively by conventional hot air drying systems because those systems depend on ambient conditions and are relatively inefficient in reducing moisture contents. These materials demand a steady low dew point dry air and a constant drying temperature, which guarantee final moisture content of 0.02% or even less. The GCD provides a closed-loop system with the dew-point of the dried air being down to -40℃ or even lower which accelerates moisture transferring from the plastic granules to the dry air.

1) Combine the function of dehumidifying, drying and two-stage conveying into single unit.

2) GCD Dryers Loaders are equipped with honeycomb rotor to obtain stable low dew-point drying air, dew-point is up to -50℃.

3) Feeding system is equipped with shut-off valve to ensure no surplus raw material in hopper tubes.

4) Microprocessor is standard equipment.

5) Heat preserved drying hopper barrel adopts down blowpipe design and collocates with cyclone air exhaust to avoid heat lost

and improve drying efficiency.

6) This dehumidifying series adopt double cooler structure to ensure lower return air temperature and dew-point value.

7) PLC control and touch HMI are optional, making operation convenient for machine’s automatic running.

8) Dew-point monitor is optional to monitor dew-point value at all times.
