The desiccant dehumidifier can operate for a long time without any damage . However,
an essential ellement feature is the maintenance procedure that you have to perform
thorougly to ensure the long life of the dehumidifier and its maximum performance
The frequency of the maintenance depends on the operation conditions and the
conditions of the working environment. If the process air is dusty, more ofte n
maintenance will be required. If the machine is not properly maintain ed , it will affect
the dehumidification performance while the lifespan of the machine will be shorten as
well.
The Dehumidifier should be shut down 15 minutes before accessing to the panel or
carry out any maintenance
procedure , such as removing the filter for cleaning purpose.
Cut off the main power before any maintenance work.
If t here is still high temperature (reactivation heating section) in the dehumidification
equipment, it is recommended to allow the machine cool down completely before
carrying out any maintenance.
Air Filter
Our desiccant dehumidifier is equipped with two air filters, one for process ing airflow
and the other is for reactivation airflow. The first filter is installed at the inlet of the
airflow and filter s the dust and particles before they enter into the desiccant wheel. If
you find the filters covered in dust and dirt, clean or replace them often in order to
provide clean and smooth air flow. Do not operate the dehumidifier without filters,
because dust and airborne particles may enter the machine and damage the desiccant
rotor. It si recommended to clean the filters once every month or at least bi monthly.
Zeolite
The zeolite nearly never needs to be cleaned. However if you observe dust or dirt, you
can clean it only using compressed air. If the dirt on the wheel still doens't come off, it
can be dismantled and washed using only water. However, it is not recommended to
wash the desiccant wheel too frequent.
