Mould Sweat Dehumidifier

H.S.Code: 8419399090
Mold Sweat DehumidifierSMD 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 0~100C, and ensures the surrounding air of mould remaining in a low dewpoint temperature. It provides constant low dewpoint surrounding air to the mould surface all year round without being influenced by the change of seasons.
Design Feature
  • Accurate control and display of regenerative temperature by using PID control.
  • Honeycomb rotor is used to ensure constant air dehumidifying effect.
  • Microprocessor board is fitted to indicate machine running status and to diagnose malfunction.
  • Motor overload and phase reverse alarm functions are included.
  • Return air cooling and filtering are included.
  • Under normal state and atmospheric conditions, the humidity content of air can be controlled exactly all year round.
  • Inhibits corrosion and prolongs service life of the mould, and yet reduces moulding cycle time.
  • Air temperature generated by this series of machine is about 300C, this ensures moisture condensation in the moulding area will not occur on the view window of the moulding machine.
  • Supplied as standard, a return air collector is used to collect return air from the moulding area back to this machine and to form a close-loop air circulation, which is particularly practical in tropical climate.
  • Dew-point monitor can be fitted as option to detect dry air quality.
  • Upon request, it can be built to comply with worldwide electrical safety standards (e.g. CE, UL, CSA, JIS etc).
