1. General Descriptionp

Read this manual carefully before operation to prevent damage of the

machine or personal injuries.

SMD-H series mould sweat dehumidifiers are designed to remove the moisture sweat from condensing on the mould surface. Forming of moisture sweat on the mould surface is due to the use of chilled water for reducing the moulding cycle time, particularly while moulding of the PET preforms. To bring about the moisture sweat on the mould surface is because the mould surface temperature is lower than the dew-point temperature of surrounding air, thus the water vapor comes into being, then causes corrosion of mould and effects quality of moulding parts as well as production efficiencies. This series of machine uses honeycomb rotor to carry out dehumidifying function, which generates a dry airflow with dew-point

ranging from +5℃~-10℃, and ensures the surrounding air of mould remaining in a low dew-point temperature. It provides constant low dewpoint surrounding air to the mould surface all year round without being influenced by the change of seasons.

Model: SMD-500H (Return air Collector is Optional)

2. Structure Characteristics and Working Principle

2.1 Working Principle

The large amount of air created by centrifugal blower will directly blow to the models of IMM after being moisture absorbed by rotator honeycomb to form drying air with low dew-point. And then air discharges through air outlet of mold closing chamber and returns to mold sweat dehumidifier through return air pipe. In this way, a circle finished. The air around mould is very dry with dew-point less than or equal to 5 ℃ . Environmental temperature drops fast during the mould rapid-cooling, but temp. would not fall to 5℃. Therefore, dewdrop would not come into being during mould rapid-cooling.

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 lower of dew point temperature (than the ambient temperature) is, the 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.

3.3 Installation

3.3.1 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 quick 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.

43(64)

Picture 3-3：What is Honeycomb-rotor

3.3.2 Installation of Honeycomb-rotor

1) The upper and lower lid of honey-comb should install Teflon gasket (Fig. 1).

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 are 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. According to 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.

62(64)

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.

Note！

Please note that some dirt, like oil mist or other types of sticky mist, is almost impossible to clean out effectively so the rotor may not be cleaned effectively and has to be replaced. This may be happened if it is polluted by exhaust gas of machines drived by diesel oil. After cleaning, the dehumidifying capacity of the rotor may be as good as before, but usually it would be affected. If you need special service for cleaning the rotor, feel free to contact us.
