Digitalization of cooling systems: how selection software, PLCs, and IoT improve system management

During the design phase, the use of selection and configuration software makes it possible to compare different solutions—chillers, cooling towers, adiabatic coolers, or dry coolers—by simulating their seasonal performance and heat loads. These digital tools also estimate energy and water consumption and help optimize system sizing.

During operation, PLCs (Programmable Logic Controllers) play a key role in system control: in cooling towers, they help optimize cooling cycles and ventilation, while in adiabatic coolers they automatically manage wetting cycles and operating modes (adiabatic or dry) based on climatic conditions.

In addition, IoT connectivity enables real-time remote monitoring of critical parameters, sending immediate alerts in the event of anomalies and allowing continuous data analysis for predictive maintenance. Thanks to IoT, technicians can monitor and intervene on the system remotely, enhancing responsiveness and reducing unexpected downtime.
