Indonesia lies in the tropical climate which requires air conditioning to increase working productivity of the people. Up to now people are still using the compressive cooling system which uses Freon as the refrigerant, which have been known to be ozone layer depleting. Therefore, new cooling system which is environmentally friendly is now in need. Desiccant cooling system manipulates the humidity condition of outside air in such a way so that the final temperature should be at 25 oC and RH of 65%. Since it does not require refrigerant which can cause environment problem, a desiccant cooling has the potential to develop in tropical country like Indonesia. In this study an experimental desiccant cooling system has been designed and constructed and tested under laboratory condition. Experimental results has shown that the resulting air temperature was 26.1 oC with RH of 55.6%. The COP was found to be 0.2
