The customer's representive, Mr. Tun taking pictures of the condensers conditions after washing the condensers.
In one morning, we came to this site to wash and clean the condensers so that there is proper air ventilation and prevent high side pressure from rising. The M.D., Mr. Dragon Lim and his engineer Mr. Lim Chin Sun were laying tray below the condensers to collect dirty water. 
In this article, we carried out maintenance of condensers washing at a special site whereby no single drop of water is allowed to drip on the floor of an office building's carpark in Singapore. The name of the building is prohibited to mention here. The location of the condensers is at one of the floor of a multi-storey carpark. Below this level of carpark are the commercial office lots. The reason why water cannot drip to the floor is because the building was constructed without water-proofing the floors. This commercial building was built more than 20 years ago.Look at the photo above, can you see what is it and what is the problem? The photo shown a corroded condenser fins covered with a thick layer of black soots and dusts. But where is black soots come from ? Why the fins corrodes ? Think about it. You tell me the answers. If your answers are right, I will give you a surprise !
