WDM-H series mould moisture dehumidifier are designed to remove the the moisture moisture 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 productioin 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 surrounging air to the mould surface all year round without being infuenced by the change of sensons.
Features of WOLTER absorption dehumidifier
1. Imported molecular sieve honeycomb rotor, featured with high temperature resistance and excellent dehumidification and long service life.
2. Specially used to dry hygroscopic engineering plastics, such as PA, PC, PBT, PET, etc.
3.PID temperature controlling system adopted, with regeneration temperature settings and real temperature display function.
4.Dew point can reach -45℃ steadily.
5.PLC control and LCD touch screen control available;
6.Return air filter is mounted inside to ensure no contamination to the honeycomb.
7. Matching with dry hopper can dry and dehumidify the raw material together.
8. Dew point Monitor (Random check or hand check ) optional.
9. This series with 12 models optional, which the largest can provide dry air up to a volume of 4000m3/h.

Honey comb rotor working principle
Working Principle of absorption dehumidifier
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 moisture dehumidifier through returen 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.
