Dehumidifier

H.S.Code: 8419399090
DehumidifierThe hygroscopic plastics materials such as Nylon, PC, PET and etc. can not be dried effectively by conventional hot air dryers, because hot air dryers are dependent on ambient conditions and are relatively inefficient in reducing moisture contents.
These materials demand  a steady low dew-point dry air (under -320C) and constant drying temperature which guarantee a residual moisture content of 0.02% or less.

Once this is achieved, these engineering plastics can exhibit their optimum physical performance and surface finish. Efficient desiccant dryers can also help the mould avoid avoid difficulties such as material shrinkage, splash and sink-marks because these dryers operate in a closed loop system dew-point of the dried air is up to -500C which accelerates the moisture transfer from the plastic granules to the dry air.

SD Series -- Dew point up to -400C)
Design Feature
  • Automatic regeneration cycle, easy to operate.
  • Dried air has a dew point of up to -400C.
  • A single dehumidifier is installed with a single hopper dryer, easy to install and maintain.
  • Small in size to save to more space.
  • Dual desiccant towers provide effective dryness.
  • Dew point monitor is optional.
  • The floor-mounted type of MD Dryer contains the dehumidifier, drying hopper and two loader. It feature in compact size, mobile, easy to maintenance, and easy to clean out.
  • MD dryers is equipped with Dry Air conveying system.

Remark:

  • With independent drying hopper;
  • Based on relative humidity 65% and ambient temperature 200C, moisture content after drying can be 0.02% or less.
  • Where marked with "*" means high efficient turbo runner blower.
SD-H Series -- Honeycle Type (Dew point up to -500C)
The molecular sieve and silica gel are strongly bonded to ceramic fibres inside the rotor does not produce any crystallization therefore, the rotor does not produce any powder and offers an extremely long service life. Moist air passes through numerous small holes in the rotor (desiccant) winch efficiently absorbs the moisture therefore, the air departing from the rotor is thoroughly dehumidified and produces extremely low dew-point dry air. Regeneration is operated under the same principle but in reverse direction through the rotor (desiccant).

Design Feature

  • Accurate P.I.D. Temp controller provides digital setting and display of regeneration temperature.
  • 24-hr timer for auto start-up operation and operation fault diagnosis automatic.
  • After cooler fitted standard.
  • Adjustable rotation speed of the desiccant rotor.
  • Mot overload and phase reversal protection.
  • Display of return air temperature.
  • Dried air has a dew-point of down to -500C.
  • Electrical circuit built to comply with CE Safety Requirements.
