Cooling towers reject heat from water-cooled systems to the atmosphere. Hot water from the system enters the cooling tower and is distributed over the fill (heat transfer surface). Air is induced or forced through the fill, causing a small portion of the water to evaporate. This evaporation removes heat from the remaining water, which is collected in the cold water basin and returned to the system to absorb more heat. Each cooling tower line, although operating under the same basic principle of operation, is arranged a little differently. 1220mm cooling tower filler specifications: Width: 1220mm Length: meet your request.
