The purpose of a cooling tower is to extract heat from water on a continuous basis. To achieve this aim, water is spread in an even film over a large surface area achieved with a modern design of packing. A draught of air of relatively low humidity is passed over the wetted film in the opposite direction. The water is then cooled by means of:
The minimum temperature to which water can be cooled by this means is 3-4°C above wet bulb ambient. For example, in a summer ambient temperature of 32°C with a relative humidity of 50% (corresponding to approximately 23.5°C wet bulb) it is possible to economically cool water to 27-28°C. However, the maximum summer temperature is reached only for short periods during a relatively small number of days.
Decsa have 60 years experience in the design and manufacture of all types of evaporative cooling towers. Built in steel or GRP with axial or centrifugal fans, open or closed circuit. We are therefore not compelled to push a particular type of design or material, only the most suitable for the needs of our clients.
The TMA range is constructed from hot dipped galvanised steel and axial fans, which make them particularly suitable for industrial applications. Their low capital and operating costs being appreciated as is their ease of maintenance.
