The cooler operation is automatically controlled by an electrical control panel provided with factory-programmed PLC according to required mode of operation.
- Dry operation: (typically winter season), the air is not pre-cooled (the adiabatic circuit is empty). The air enters the cooler from the top (dampers open, where provided), or crosses the dry adiabatic media (adiabatic circuit off).
- Adiabatic operation: (typically peak summer season), the air undergoes an adiabatic pre-cooling process. The air enters the cooler from the lower part and passes through the adiabatic media (dampers closed and adiabatic circuit on).
- The unit can be controlled via remote BMS control
