Product Description

Industrial  Dehumidifier for PET preform

Application

HDDR series mould moisture dehumidifier are designed to remove the the 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 +5ºC~-10ºC, 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 seasons.

Features of Hadrdega Mould Moisture Dehumidifier

1.Accurate control and display of regenerative temp. by using P.I.D. control.

2.Honeycomb rotor is used to ensure constant air dehumidifying effect.

3.Microprocessor board is fitted to indicate machine running status and to diagnose malfunctions.

4.Motor overload and phase reverse alarm fuctions are included.

5.Return air cooling and filtering are included.

6.Under normal state and atmospheric conditions, the humidity content of air can be controlled exactly all year round.

7.Inhibits corrosion and prolongs service life of the mould, and yet reduces mouding cycle time.

8.Air temperature generated by this series of machine is about 30ºC, this ensures moisture condensation in the moulding area will not occur on the view window of the moulding machine.
