Cooling tower heat exchanger is a device to reject heat or cooling of a water stream to a lower temperature which draw out waste heat to the upwards. Fouling is the most serious problem in heat exchanger operation that could be detected when the surface temperature increase nears to the critical temperature. Thus, maintenance crew is required to approach cooling tower for measuring the surface temperature on the top of the cooling tower which distribute hot air that may result less accuracy reading and harmful to user. This study is conducted to construct a mobile heat carrier detecting device to monitor and measure the surface temperature by using RC Quadcopter and thermocouple device using the addition of custom bracket or mounting. Thermography device was used to determine the effectiveness reading of thermocouple by comparing both of their accuracy. Material and device selection is conducted before fabricating and assembling process begun. Thermocouple mounting device was successfully fabricated and applied for carrying the device to measure upon cooling tower surfaces. Meanwhile thermography device used conventional method which is by hand held technique. All of the temperature data were tabulated in table and constructed in a mapping tool for ease of comparing and temperature distribution view. The characteristics of surface temperature distributions were obtained in different regions of 3 specific points of each fan. CT 1 indicates the highest range of surface temperature from 43.2 °C until 53.5 °C by measuring with thermography. Thermography measured higher value of temperature compared with thermocouple device due to thermography high accuracy of reading (±0.2 °C).
