The plates showed in this new video on our Tempco YouTube channel<\/strong><\/a> are very particular plates for plate heat exchangers<\/strong><\/a>, characterized by very wide channels<\/strong>. These are called Free flow plates<\/strong><\/a>, indeed having large channels and having no contact points<\/strong>.<\/p>\n

Usually, plate heat exchangers increase their thermal transfer efficiency<\/strong> when the number of contact points between the plates increases, thus increasing the turbulence rate of fluids<\/strong><\/a>. But these contact points also become spots for the settlement of dirt, when the exchangers work with dirty fluids rich in suspended particles<\/strong>.<\/p>\n

Free flow plate heat exchangers<\/strong> were then born in order to avoid this problem. In Tempco we\u2019ve recently supplied a couple of free flow exchangers with DN150 connections aimed at cooling water for die plates<\/strong> in wire drawing of plastic materials<\/a><\/strong>. In fact, during the wire drawing process, a plastic material wire comes out of the wire plate and gets collected in a tank containing cooling water. The plastic wire then proceeds to the cutting section, where plastic granules<\/strong> are produced.<\/p>\n

Cooling water then becomes clearly full of plastic dusts and plastic chips<\/strong>. Using traditional plate heat exchangers in this particular application, the exchangers would become clogged in a very short time lapse<\/strong>.<\/p>\n
