The evaluation of the <strong>amount of kW to be dissipated<\/strong> is therefore easy to do, being it <strong>directly proportional to the current employed<\/strong> to achieve the anodic oxidation and the voltage of it.<\/p>\n<p><iframe loading=\"lazy\" width=\"750\" height=\"422\" src=\"https:\/\/www.youtube.com\/embed\/bTq7PXy7tRg?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen title=\"Come calcolare il carico termico negli impianti di ossidazione anodica\"><\/iframe><\/p>\n<p><strong>Temperature levels<\/strong> of the galvanic bath then vary depending on the kind of anodic oxidation. In case of <strong>hard anodic oxidation<\/strong> plants, the required temperatures are quite low, <strong>between 10\u00b0 C and 15\u00b0 C<\/strong>. <strong>Traditional anodic oxidation<\/strong> processes require instead temperatures <strong>between 20\u00b0 C and 25\u00b0 C<\/strong>.<\/p>\n<p>Cooling at these temperatures, unless huge amounts of artesian well water at temperatures of 10-12\u00b0 C are available, leave not too many options. <strong>Chillers and refrigerating groups<\/strong> are indeed required, even because the secondary circuit of the exchanger must be fed with water at a temperature of 10-15\u00b0 C, depending on the type of anodic oxidation.<\/p>\n<p>Subscribe here to our <strong><a href=\"https:\/\/en.tempco.it\/newsletter-solid-temperature\/\" target=\"_blank\" rel=\"noopener\">Tempco Newsletter &#8211; Solid Temperature<\/a><\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>How to evaluate the thermal duty to be dissipated in cooling and thermostatation of anodic oxidation plants, in order to properly size heat exchangers and chillers. <\/p>\n","protected":false},"author":5,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[64,63,113],"tags":[1120,655,112,1237,2807,127,495,2809,2805,138,2806,1543,2682,2808],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v20.5 -
