Control Settings
Once the unit is positioned correctly, required duct work attached and the
power supply connected, the process fan speed and temperature control need
to be set correctly.
The fan speed control is located within the main electrical control. The
controls are numbered 1 to 10, with 10 being the maximum speed.
For normal (efficient) operation the process airflow should be set to 3000m³/h
(1766 cfm). Measurements should be taken at the duct outlets using a
suitable instrument.
The regeneration air flow is fixed and cannot be adjusted. Setting of the
correct airflow is to be carried out by the installation of a damper control
within the regeneration outlet airstream,
The temperature control regulates the temperature of the reactivation airflow
onto the desiccant wheel. The control can be set up to a maximum of 145°C
The controller displays the set value (Green display) and also the actual value
(Red display)
To adjust the temperature control simply press the
▲
or
▼
buttons to select
the required setting. The controller will automatically store this value.
The temperature setting should be set to 90°C above the ambient
temperature of the area being dehumidified
If high moisture extraction is required it will be necessary to increase the
process airflow. The temperature control setting should also be increased.
If very low humidity levels are required then the process airflow should be
reduced.
The following table should be used as a guide:
