The challenge: a completely blocked heat exchanger filled with glued residues
Place of application: Kipp Umwelttechnik’s blasting hall
*Performance data: 130 l/min, 150 bar
High pressure cleaning
In order to preserve delicate fins, the high-pressure cleaner is equipped with a flat film extrusion nozzle. The pump pressure was confined to 100 bar, so the delicate fins won’t get damaged. Furthermore, a special focus was put on treating the heat exchanger’s fins arrangement from a 90° angle. Otherwise, there would be a risk of damaging them, even with lower pressure.
The result
The application of the high-pressure cleaner visibly showed no cleaning success. The bigger part of used water rebounded off the heat exchanger’s surface. Further observation showed that there was just a minor, doting water outlet on the backside coming from a small space.

The result
The heat exchanger was cleaned thoroughly and its functionality could be restored to mint condition. Merely about 1 l of water/min was applied which exited on the back of the heat exchanger in a widespread manner.
