1 How to cool a D E S Y?
2 Welcome in the world of JAEGGI! JAEGGI/Güntner (Schweiz) AG Hybrid Dry Cooler More then 10 years experience in wet and dry systems => hybridtechnology Ing. Ludwig Rosner Ing. Walter Müller
3 ??? Cooling System??? Different cooling systems on the market! Technical demands have to be fixed how to select based on the demands => optimal solution for a special application.
4 Technical requirements for DESY Medium outlet temperature < ambient temperature Operating without producing mist (steam)=> acceptance Minimal water consumption => min. operating costs Closed one circuit system with fully demineralized water High capacity => between 1 und 20 MW Low space requirements of the units High difference between water IN and water OUT (delta T) Minimal sound pressure level & min. power consumption The tube materials must fit to the other materials Exactness of the regulation (water outlet temperature) Protection from freezing
