DehumidifierH.S.Code: 8419399090
|
The 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

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.

Why use Dehumidifier?
|
Low
Water Content
The
Relation between PET's Strength and its Water Content
For PET, when its water content is over 0.02%, its
shock resistance, elongation performance and tensile strength
reduce too much.
