commonly used as a heat transfer fluid in heating, ventilation, air conditioning, and refrigeration (HVAC-R) systems.<br>There are two main types of glycol used in cooling systems:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Ethylene glycol (EG): very efficient from a thermal and fluidity point of view, but unfortunately quite toxic;<\/li>\n\n\n\n<li>Propylene glycol (PG): more viscous, it is also slightly less efficient. However, it is better suited for certain uses, such as food processing, pharmaceuticals, etc.<\/li>\n<\/ul>\n\n\n\n<p>Most often mixed with water (the glycol content of the mixture is then expressed as a percentage), glycol forms an antifreeze solution which circulates in the cooling system.<br>Its main functions are:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Lowering the freezing point:<\/strong> Glycol prevents water from freezing in pipes at low temperatures, which could damage equipment.<br>(Example: A 50% glycol solution can protect down to approximately -35\u00b0C.)<\/li>\n\n\n\n<li><strong>Raising the boiling point<\/strong>: It also allows the fluid to operate at higher temperatures without boiling, useful in some industrial systems.<\/li>\n\n\n\n<li><strong>Preventing corrosion:<\/strong> Glycol solutions often contain corrosion inhibitors that protect metal components (such as aluminum, copper, or steel) from rust.<\/li>\n\n\n\n<li>And finally, <strong>improving heat transfer<\/strong>: Even though pure glycol has a lower heat capacity than water, it remains effective as a heat transfer fluid in demanding environments.<\/li>\n<\/ol>\n\n\n\n<p>It is therefore naturally found in many &#8220;cold&#8221; devices: industrial and commercial cold units, coolers (or chillers) for cooling buildings or machines, process cooling systems (e.g.: breweries, laboratories), etc.<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-columns alignwide is-layout-flex wp-container-core-columns-is-layout-28f84493 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<p><span style=\"text-decoration: underline;\">Released on:<\/span> June\/18th\/2025<br><em><span style=\"text-decoration: underline;\">We&#8217;re also being talked about elsewhere on the web too:<\/span> <a href=\"https:\/\/news.google.com\/search?q=eurodifroid&amp;hl=fr&amp;gl=FR&amp;ceid=FR%3Afr\" data-type=\"link\" data-id=\"https:\/\/news.google.com\/search?q=eurodifroid&amp;hl=fr&amp;gl=FR&amp;ceid=FR%3Afr\" target=\"_blank\" rel=\"noopener\">EURODIFROID on Google News<\/a><\/em><\/p>\n\n\n\n<p><\/p>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Design of a cooling unit (heat exchanger) for a hydrogen station It takes a lot [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":5831,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[75,68,1],"tags":[],"class_list":["post-5828","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-hydrogen-and-renewable-energies","category-water-cooling","category-news"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.eurodifroid.fr\/en\/wp-json\/wp\/v2\/posts\/5828","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.eurodifroid.fr\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.eurodifroid.fr\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.eurodifroid.fr\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.eurodifroid.fr\/en\/wp-json\/wp\/v2\/comments?post=5828"}],"version-history":[{"count":8,"href":"https:\/\/www.eurodifroid.fr\/en\/wp-json\/wp\/v2\/posts\/5828\/revisions"}],"predecessor-version":[{"id":8662,"href":"https:\/\/www.eurodifroid.fr\/en\/wp-json\/wp\/v2\/posts\/5828\/revisions\/8662"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.eurodifroid.fr\/en\/wp-json\/wp\/v2\/media\/5831"}],"wp:attachment":[{"href":"https:\/\/www.eurodifroid.fr\/en\/wp-json\/wp\/v2\/media?parent=5828"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.eurodifroid.fr\/en\/wp-json\/wp\/v2\/categories?post=5828"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.eurodifroid.fr\/en\/wp-json\/wp\/v2\/tags?post=5828"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
