Solitamente i tubi vengono mandrinati direttamente con il pacco alettato e resi solidali mediante lo stesso processo con le spalle in acciaio. Questo sistema \u00e8 utilizzato ormai a livello generalizzato, ma in alcuni casi quando si hanno forti escursioni termiche fra l&#8217;ambiente circostante ed il fluido da raffreddare, diventa molto utile avere il <strong>pacco di scambio &#8220;flottante&#8221;<\/strong>, ovvero montato su boccole che ne permettono lo scorrimento, in modo da escludere sollecitazioni sui tubi in rame, in caso di dilatazione o contrazione.<\/p>\n<p>Questo tipo di lavorazione, annulla il rischio di rotture indesiderate dei tubi nella zona di contatto con la struttura di supporto, eliminando costosi interventi di riparazione e fermi impianto indesiderati.<\/p>\n<p><a href=\"http:\/\/www.friga-bohn.com\/\">Friga Bohn<\/a> partner di <a href=\"http:\/\/www.tempco.it\/\">Tempco<\/a> per i sistemi di <a href=\"https:\/\/www.tempco.it\/soluzioni\/raffreddatori-industriali-elettroradiatori\/\" target=\"_blank\" rel=\"noopener\">free cooling<\/a>, realizza da sempre una gamma di macchine realizzate con questo sistema.<\/p>\n<p style=\"text-align: center;\"><a href=\"https:\/\/www.tempco.it\/blog\/wp-content\/uploads\/2009\/01\/eca-tubes-in-guide-before-expanding.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-thumbnail wp-image-651\" title=\"eca-tubes-in-guide-before-expanding\" src=\"https:\/\/www.tempco.it\/blog\/wp-content\/uploads\/2009\/01\/eca-tubes-in-guide-before-expanding-150x150.jpg\" alt=\"T FIN TCFC free cooler\" width=\"150\" height=\"150\" \/><\/a>\u00a0<a href=\"https:\/\/www.tempco.it\/blog\/wp-content\/uploads\/2009\/01\/eca-floating-coil.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-thumbnail wp-image-652\" title=\"T FIN TCFC free cooler pacco alettato flottante\" src=\"https:\/\/www.tempco.it\/blog\/wp-content\/uploads\/2009\/01\/eca-floating-coil-150x150.jpg\" alt=\"T FIN TCFC free cooler pacco alettato flottante\" width=\"150\" height=\"150\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>I free cooler sono macchine abbastanza semplici, in pratica si tratta di radiatori abbinati a ventilatori, per poter raffreddare l&#8217;acqua [&hellip;]<\/p>\n","protected":false},"author":3,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3,19,6,4,26,10,9],"tags":[],"class_list":["post-650","post","type-post","status-publish","format-standard","hentry","category-energia-termica","category-free-cooler","category-free-cooling","category-raffreddamento","category-recupero-energetico","category-risparmio-energetico","category-scambiatori-di-calore"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.6 -
