Application of cooling fans or panel fans includes condensing units, processes and general ventilation, foundry ventilation, warehouse ventilation, factory ventilation, and many more.
In case of cooling application – A cooling fan is generally switched on when the temperature rises and to reduce the temperature, the thermostat in a cooling fan would be wired generally in an open position.
In the case of heating application – A cooling fan is generally switched on when the temperature lowers down to a certain point and to increase the temperature, the thermostat in a cooling fan would be wired generally in a closed position.
Here, the enclosure thermostat works with a heating or cooling device to maintain a safe working temperature within the enclosure for safeguarding against condensation, humidity, and frost. They can be wired as normally opened or closed, following the application. The enclosure thermostat in general not connected to the PLC, but sometimes it could be displayed as an enclosure internal temperature alarm. In this scenario, the enclosure thermostat is connected directly with the cooling fan on doors and switches independently of the PLC.
