How Would Your Plant Have Done?


During a recent observation of a CCR console operator, he received a high temperature alarm on the outlet of a fin fan exchanger. Seeing that all fan motors were “on,” he suspected a broken belt and had the field investigate. His diagnosis was confirmed, a replacement was secured, the breaker was locked out, and a secondary mechanic installed the new belt. Total elapsed time from alarm actuation to the fan being back in service was approximately 25 minutes.

Almost more impressive than the speed with which this was done was the routine manner with which the crew handled it. It was not a rush-rush situation, but a trained group of personnel that knew how to do their job and did it in a methodical, but expedient manner. No reduction in unit rate was needed due to the short time without the fan. How would this have played out at your plant?
