OPERATING INSTRUCTIONS

TrilliumSeries Coolers with EC fans & factory installed
control panel
Each unit is equipped with a control panel and a power panel.
The fan speed is controlled and the adiabatic pre-cooling is activated by a PLC integrated into the electrical panel.

Control logic

The fan speed is controlled on the basis of the actual process fluid temperature at the exit of the unit and the design
leaving temperature, ensuring a minimum in electrical consumption and noise levels.
The adiabatic pre-cooling will be activated and stopped on the basis of a pre-programmed logical combination of
the fan speed and the ambient temperature (release set-point). Default settings will not activate adiabatic pre-
cooling unless all fans are running at maximum permissible speed and the dry-to-adiabatic release set-point is
reached.
The adiabatic control logic is pre-programmed and is ready for operation.
Depending on the actual size of the installation, the controller pre-programmed PI process parameters may need to
be adjusted.
