Contamination or damage in large combustion plants can often not be precisely localized. Although the system sensors report deviations from the standard values, they hardly allow any detailed conclusions to be drawn about the actual causes. The EICHNER IndustrieService team has developed special cameras to enable the exact position, type and extent of the fault to be recorded in advance of industrial cleaning. These cameras can be used to carry out boiler or system inspections during production operation - at temperatures of up to 1,600 degrees Celsius.
