Which cooling system is the better choice to obtain cooling water for production processes<\/strong>, among chillers<\/strong><\/a>, evaporative towers<\/a><\/strong> or dry coolers<\/strong><\/a>, is a very often requested topic. The choice depends first of all on the temperature level of the water required<\/strong>. Clearly, if water at 10\u00b0 C is needed, or even at 0\u00b0 C or under zero, the only way to go is a refrigerating group, or chiller.<\/p>\n

But there are several halfway situations too, where cooling water required has slightly higher temperature levels, such as 20-25 or 30\u00b0 C. Which still is cold water, but it can be obtained leveraging other kind of cooling systems. Each one offering its benefits and disadvantages, clearly.<\/p>\n

The refrigerating group<\/strong><\/a> is the one that is less affected by climatic conditions<\/strong>, if properly designed. There are also chillers tropicalized, able to operate also at high ambient temperatures, and with to special equipments enabling operations as well during the winter season. We\u2019re talking here about EC fans<\/strong><\/a>, that provide the adaptation of the condensation speed.<\/p>\n

When cooling water is required at temperatures of 25-30\u00b0 C<\/strong>, that’s when the doubts start, if it\u2019s better choosing a chiller, an evaporative tower or a dry cooler. It all depends on the climatic conditions<\/strong>. An evaporative tower<\/strong><\/a> employed at latitudes typical of North or Central Italy, and Europe, allows to obtain cold water at a temperature of approximately 29-30 or 31\u00b0 C. Here, a dry cooler<\/strong><\/a> struggles, just because it\u2019s cooling work depend strictly upon the ambient temperature. So that during the summer season, when temperatures reach 30-35\u00b0 C, it will be possibile to obtain cooled water at temperatures 5\u00b0 C higher, and so that means water at 35-40\u00b0 C. Furthermore, it\u2019s true that during the winter season, or the mid-season, a dry cooler allows to have cold water at the required temperature.<\/p>\n
