After performing a site survey on an air cooled cooler installation of one of our valuable customers, it was noticed that the mechanical integrity of the fan-units and air chamber (plenum) originally delivered by Bronswerk in 1975 was almost at the end of his life and needed replacement.

After redesign, manufacturing and transport of the fan-units and air chamber, the replacement one site was safely executed by the Bronswerk installation team.

The air cooler bundles were re-used and since the installation was out of operation the opportunities is well used to externally clean the finned tube bundles using our dry online cleaning method.

With this intervention, the mechanical integrity and operational reliability is safeguarded.
