Air Coolers

[padovano]

I would like somebody to advise me on the best ways of daily monitoring aircoolers. I am talking about methods which will indicate the fouling of the aircoolers. In the process division where I am working, there is nothing like that. Maintenance on the aircoolers are been carried out base on reports from inspectors.

Have you thought of daily monitoring of inlet/outlet temps.
and logging this data? If the plant is operated on a DCS system, this is quick program change to incorporate the data logging in a pull down file and setting up an alarm function when the delta T becomes too small.
