Among other a main concern in deluged heat exchangers is the effect of fouling on thermal performance and the overall lifecycle.  A containerized fouling test rig, consisting of four small cooling towers is therefore being designed and will be installed at Green Energy Park, Iresen in Morocco.  The cooling towers will enable multiple accelerated investigations to determine the effect of fouling for different water compositions and various tube materials.  Through the tests, effects of the following on thermal performance will be investigated:

• Scaling due to various salt compositions and concentrations
• Particle deposition due to different soil concentrations
• Water acidity
• Various rinsing strategies
• Tube temperatures

The collector cleaning technologies developed and tested by Ecilimp, Spain, will also be demonstrated at Green Energy Park (Morocco).
