Behind the choice between a ventilated and a sealed electrical cabinet lies a much broader issue: ensuring the reliability of the installation over many years despite environmental constraints.<br\/> <\/p>\n\n<p class=\"wp-block-paragraph\">Humidity, dust, heat emitted by equipment, corrosive atmospheres, and significant temperature variations directly influence the performance of an electrical cabinet. A poor choice can lead to component overheating, condensation, premature corrosion, or costly maintenance.<br\/> <\/p>\n\n<p class=\"wp-block-paragraph\">This is why polyester enclosures have become a preferred solution in many industrial sectors. Thanks to their natural corrosion resistance, excellent electrical insulation, and mechanical robustness, they perfectly meet the requirements of outdoor installations or harsh environments.<br\/> <\/p>\n\n<p class=\"wp-block-paragraph\">But should you choose a completely airtight cabinet or a ventilated one? The answer depends less on the product itself than on the actual constraints of your project.<br\/> <\/p>\n\n<p class=\"wp-block-paragraph\">In this guide, we help you make the right choice based on your environment, your thermal balance and the expected IP\/IK protection level.<br\/><\/p>\n\n<div style=\"height:41px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<h2 class=\"wp-block-heading\"><strong>First and foremost: understand the criteria that influence the choice of a polyester wardrobe<\/strong><\/h2>\n\n<div style=\"height:41px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<p class=\"wp-block-paragraph\">Ventilated cabinets are often contrasted with sealed cabinets.

Variable speed drives, power supplies, PLCs, converters, and power electronics can dissipate several hundred watts within a single enclosure. Without air circulation, the temperature rises rapidly, reducing component performance and accelerating aging.<br\/>  <\/p>\n\n<p class=\"wp-block-paragraph\">A ventilated cabinet allows this heat to be evacuated while maintaining a more stable operating temperature.<\/p>\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<h3 class=\"wp-block-heading\"><strong>Why ventilate an electrical cabinet?<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">The main purpose of ventilation is to remove the heat produced by electrical components in order to maintain a temperature compatible with their operation.<br\/><\/p>\n\n<p class=\"wp-block-paragraph\">It is particularly relevant when:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>the cabinet contains several speed controllers;<br\/><\/li>\n\n\n\n<li>Power supplies or converters dissipate a significant amount of power;<br\/><\/li>\n\n\n\n<li>the automated systems operate continuously;<br\/><\/li>\n\n\n\n<li>The installation is located in an enclosed technical room.<br\/><\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">By promoting air renewal, properly sized ventilation limits hot spots and improves the lifespan of equipment.<\/p>\n\n<p class=\"wp-block-paragraph\">In this type of configuration, a ventilated polyester cabinet offers an excellent compromise between protection, thermal performance and ease of maintenance.<br\/><\/p>\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<h3 class=\"wp-block-heading\"><strong>What impact on the IP index?<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">This is a point that is often misunderstood.<br\/><\/p>\n\n<p class=\"wp-block-paragraph\">Adding a fan, filter grille, or opening automatically changes the overall protection level of the cabinet.<br\/><\/p>\n\n<p class=\"wp-block-paragraph\">For example :<\/p>\n\n<ul class=\"wp-block-list\">\n<li>An IP66 cabinet equipped with an IP54 filter grid will no longer be considered IP66;<br\/><\/li>\n\n\n\n<li>Its overall protection rating will be reduced to the level of the least efficient component.<br\/><\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">This rule is directly linked to the NF EN 60529standard .<\/p>\n\n<p class=\"wp-block-paragraph\">This does not mean that a ventilated cabinet offers less protection. However, it should be reserved for environments compatible with this level of protection. <\/p>\n\n<p class=\"wp-block-paragraph\">Indoors, an IP54 or <strong>IP55<\/strong> rating is generally sufficient.<br\/><\/p>\n\n<p class=\"wp-block-paragraph\">Outdoors, it is advisable to prioritize solutions incorporating protective covers, specific fans or suitable cooling

solution to choose?<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">Not all installations require an industrial air conditioner.<\/p>\n\n<p class=\"wp-block-paragraph\">The choice depends primarily

risks that your installation will face.<\/p>\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<h3 class=\"wp-block-heading\"><strong>First criterion: the environment<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">Ask yourself the following questions:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>Will the cabinet be installed indoors or
