subject: Evaporative cooling towers [print this page] Evaporative cooling towers are widely used for the rejection of processed waste heat in all industry sectors - including mining, steel, food processing, paper, sugar, chemicals and petrochemicals, dry-cleaning, plastics, air-conditioning and power generation. Their use allows cooling to temperatures approaching the air Wet-Bulb temperature. The recirculation of cooling water through the tower eliminates the need to locate the process plant near a large source of water, or use endless amounts of "fresh" water daily.
When liquid evaporates, the amount of latent heat required to cause its evaporation is removed from the remaining liquid, which is cooled. In this case, there is a net heat flow from the water flowing through the heat exchange filling material, which is itself a heat source and is cooled, through the remaining liquid to the water vapor taken up by the air stream, which will be imperceptibly heated. This principle is used in all forms of evaporative cooling.
Tektower (formerly Sulzer Cooling) manufactures a whole range of evaporative cooling towers from the smallest fiberglass units for air-conditioning applications to site assembled modular units for large manufacturing plants and mines to the concrete or galvanized steel units for the really large applications. All towers are manufactured to the exceptionally high quality standards associated with Sulzer products internationally.
Tektower is one hundred percent South African owned and are proud of the fact that 95% of their Cooling Tower products are produced in South Africa.
More than 11 000 of their units have been installed in a wide range of applications throughout South Africa and the sub continent including Sudan, Kenya, Zambia, Nigeria, Mozambique and Mauritius to name a few. Many of the original units are still operating today.
