Mould Sweat DehumidifierH.S.Code: 8419399090
|
 SMD
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).
