Icing Monitoring on Cooling Tower
In addition to monitoring high temperatures, LWIR thermography can also be used to monitor low temperatures, for example to monitor the icing on cooling towers. Since the temperatures are monitored in the LWIR range, the measurement is not influenced by daylight or lighting systems.
The monitoring can thus be efficiently performed outdoors, especially since the camera housing and PTH are weatherproof. Due to the geometric dimensions of the cooling tower, a pan-tilt head is used to ensure optimal monitoring.
The ARTUS system sets off an alarm if the temperature falls below the specified operating temperature of the cooling surface or if icing occurs when temperatures fall below the freezing point. Depending on the facility, the surface is then de-iced or the cooling capacity is reduced.
A PC located at the facility is used to configure the system and conduct the continuous visual monitoring while simultaneously running the automated alarm triggering function.
