operation. Keep this equipment away from flammable sources at least two
meters.

6) Avoid vibration, magnetic disturbance at the operation area.

Rejected parts disposal
When the equipment has run out its life time and can not be used any more,

unplug the power supply and dispose of it properly according to local code.
Fire hazard

In case of fire, CO2 dry powder fire extinguisher should be applied.

1.4.4 Safety Regulations for the Blowers

1) Under normal operation, the blowers will generate high temperature. Do not
touch blower's case to avoid any physical injury.

2) Under normal operation, the blower motor's current loading will increase or
reduce according to air pressure's change accordingly. While installation, an
adequate motor overload protection switch should be installed with full
loading test, to ensure operating safely under full-loading to avoid motor's
damage.

3) To avoid any block materials, dust, powder, fiber particles and water drops
entering the blower, and hence cause the deficiency of its performance. This
machine is well designed with air filters, so please clean up the filter with any
foreign particles (recommended to clean up this filter weekly).

4) Clean the blowers both internal and external parts (especially for the fan
cooling path), and remove surface dust if necessary. If more dusts are
accumulated, it will cause deficiency for ventilation, temperature rising,
vacuum power reduced, vibration increased and so it will cause machine
broke down.

5) Ball bearing, oil seal and soundproof are belonging to consumable parts and
so it has a life period and requires regular replacement. Meanwhile, blade,
external case, and metallic screen etc. should be replaced regularly for best
performance.

6) Under normal operation, if the blowers are not running smoothly or abnormal
noise appeared. Please immediately shut down the machine for repair.

2. Structure Characteristics and Working Principle

2.1 Working Principle

The moisture contained in the air which is waited for treating) will be absorbed
by hygroscopic materials, hereafter, be de-absorbed by the regenerated hot air.
And the two airstream work together in the rotation wheel. So, with the rotation
of the wheel, moisture will be absorbed and de-absorbed continuously, and
drain out via de-absorbing by regenerated air to form a steady low dew point
airstream for using.

2.2 Relative Humidity and Dew-point

Relative humidity: Relative air humidity means real vapor content to saturated
vapor at the same temperature in percentage.

Dew point: it means that temperature when the saturation vapor begins to dew.
When the relative humidity is 100%, the ambient temperature is the dew point
temperature. The more lower of dew point temperature (than the ambient
temperature) is, the more less possible to dew, that also means the more drier
the air is. The dew point will not be influenced by temperature, but influenced by
pressure.

2.3 Why Choose SD-H

The main reason for the defects of plastic products, such as bubbles, silver lines,
flaws, poor transparency, etc. is that plastic raw materials are not completely
dried before moulding. Hygroscopic plastics, such as PA, PC, PBT, PET,
NYLON and so on, can not be thoroughly dried through traditional methods. It is
proved that heated and dehumidified air with low dew-point down to -40 ℃ can
make moisture content of such materials over than 0.02% before moulding.
SD-H honeycomb dehumidifiers, utilizing honeycomb-rotor in a full-closed
system to dehumidify process air, can meet such requirements. Hot air with low
dew-point produced by this unit is quickly and continuously blowed to plastic
particles to completely absorb the moisture, thus to gain a good drying and
dehumidifying effect.

3.2 Honeycomb-rotor

3.2.1 What is Honeycomb-rotor?
The main body of the honeycomb-rotor is a honeycomb, made by ceramic fibre

and organic additives, sintered under high temperature with molecular sieve and
silica gel, to be strongly bonded together and form a solid and hard surface. Not
like common molecular sieve, which will produce dusts and fines to pollute raw
materials when aging or become saturated requiring regular replacement,
honeycomb-rotor offer unlimited long life and can be cleaned when it is polluted.
The moisture of return air is quickly absorbed by numerous tunnels before
coming out of the rotor to form low dew-point air. At the same time, regenerating
blower takes dry air into the honeycomb-rotor from an opposite direction to
regenerate the rotor.

6.1 Honeycomb

Honeycomb Rotor cleaning steps:

1) Use a vacuum-cleaner with brush to suck up the dust on rotor surface.

2) Blow off the dust in the rotor channels with compressed air.

3) If there is dirt sticking to the channel walls inside the rotor, cleaning steps as
follows:

a. Saturate the rotor by blowing humid air (higher than 60%RH) through the

rotor without having regeneration circuit on. This can be done by just
turning the regeneration heater off and still have the process blower
running if process air has high humidity. If the process air is too dry try to
put a humidifier in the air stream. Do this for one hour.

b. Depending on the character of the dirt, sink the rotor into water with

cleaning agent in it (PH value 3~2 liquid is applied to silica gel, PH value
7~10 applied to molecular valve). Greasy dirt should be put into a
detergent solution with xylene. 15 minutes cleaning is suggested.

c. Take the rotor out of the liquid and let it rest with the channels vertically for

5 minutes so the liquid can run out.
d. Blow off the residual liquid in the channels with compressed air.
e. Put the rotor back into the dehumidifier and run the unit with regeneration

circuit (the regeneration temperature between 50℃ and 60℃) on for at

least one hour.

Note:

1. Note that in the dry air and wet air outlets, there will be high
concentrations liquid out for some time. If a solvent has been used,
there will be a residual smell for several days.

2. For some dirt which is greasy and sticky in the rotor, 100% elimination
is impossible. The only one thing you can do is to replace the rotor for
the cleaned rotor performance can only be recovered partly.

6.2 Filter

Please periodically clean the dust on the air filters, once per week.
Cleaning steps：

1) Take out the air filter carefully.

80(83)

2) Blow off the dust on the air filter screen and the cover with pressure air.

3) Wipe off the barrel wall of air filter with dishcloth.

4) After cleaning, place all parts in reversed order carefully.

Picture 6-1：Filter

Note!

Do not let any impurities fall into filter container.

6.3 Cooler

1) Clean the cooler and eliminate the leakage regularly.

2) Please do the above-mentioned job once a month for cooling by chilled water.
As for the cooling by normal water, do the same job once a quarter.

Cooler clear step

1) Disassemble the cooler's pipe and screw, and remove the cooler out of the
chiller.

2) Release the fixed screw on the upper and lower cover of cooler and
disassemble the cover.

3) Use brushes, compressed ed air or low pressure water to clean the dust and
sundries on the cooler fan and copper pipe.
Notes: water residue on the cooler fan and copper pipe should be dried with
compressed air.

4) Make the cooler's upper and lower cover junction clean enough and smear
the silica gel then fixed the covers with screws.

5) Put the cooler on the air at least 4 hours to make the silica gel drying enough
then fix the cooler on the chiller and connect all pipes.
