Air-water exchangers keep things cool
One of the best ways to cool beer on a day out is to have a good time on the river, where the moisture makes the air cooler. The result is a rapid transfer of heat, and so the liquid in the bottle quickly matches the outside temperature. Likewise, in industrial settings, air-water exchangers are a very good solution. This is especially true for situations complicated by an aggressive external environment or by the need to control clean air in facilities. Examples include chemical industries, cement plants, mines, foodstuffs, pharmaceutical, and so on. When deciding to use an air-water exchanger, it is usually because the air temperature is too high, more than 40 o C. Also, it could be that the quality of the air outside makes it impossible to work with ventilation, air conditioner or other solutions that need outside air for cooling. For instance, in the case of cement plants, filters are quickly blocked due to airborne particulates. Paper mills, printing facilities or chemical pla...
