What makes brazed plate heat exchangers<\/strong><\/a> for CO2 refrigeration<\/strong><\/a> applications that special? At first glance, looking at them they really seem similar to traditional brazed plate exchangers.<\/p>\n

Differences start getting clear while handling them, and these are due to special construction processes<\/strong>. In fact, the weight is different<\/strong>, because of the special brazing processes employed that allow these exchangers to stand working conditions with high pressure levels up to 140 bar<\/strong>, which are involved in refrigeration applications using CO2<\/a> as a refrigerant. Therefore, really quite remarkable pressure levels.<\/p>\n

Another difference is related to the connections<\/strong>, that from the outside are looking very much alike traditional outer threaded connections<\/strong>. But watching more closely, we can see there is also an inner part<\/strong>, which is a threaded solder connection<\/strong>. These are combi type connections, meaning they offer a combination of connections with the outer threading that can be employed for water or non freezing solutions<\/strong>, while the inner part is a threaded solder connection with standard diameters usually employed in refrigeration related applications.<\/p>\n
