The main points to check are the followings:<\/p>\n<p><strong>Cleanliness and condition of <a href=\"https:\/\/en.tempco.it\/solutions-en\/heat-exchangers\/\" target=\"_blank\" rel=\"noopener\">heat exchangers<\/a><\/strong>. Heat transfer surfaces must be clean and free of deposits or <a href=\"https:\/\/www.tempco.it\/blog\/en\/9511\/fouling-factor-each-type-of-exchanger-has-his-own\/\" target=\"_blank\" rel=\"noopener\">fouling<\/a>. Even a thin layer of fouling can significantly reduce the overall heat transfer coefficient (U), degrading the unit&#8217;s rated performance. The check must include both the process and service sides.<\/p>\n<p><strong>Water circuit and water quality<\/strong>. Pipe scaling, localized <a href=\"https:\/\/www.tempco.it\/blog\/en\/8217\/heat-exchangers-and-corrosion-of-materials-in-anodic-oxidation\/\" target=\"_blank\" rel=\"noopener\"><strong>corrosion<\/strong><\/a>, and deterioration of cooling water quality are among the most common causes of problems during the summer season. It&#8217;s important to <strong>check the pH, hardness, and concentration of any inhibitors<\/strong>, as well as verify proper circulation within the circuits.<\/p>\n<p><strong>Ventilation and condensation components<\/strong>. In <a href=\"https:\/\/en.tempco.it\/solutions-en\/industrial-coolers-electroradiators\/\" target=\"_blank\" rel=\"noopener\"><strong>dry coolers<\/strong><\/a> and <a href=\"https:\/\/en.tempco.it\/solutions-en\/cooling-towers\/\" target=\"_blank\" rel=\"noopener\"><strong>evaporative cooling towers<\/strong><\/a>, the condensation section is the first to be affected by high external temperatures. Checking that the <strong>fans are working properly<\/strong>, that the fins are clean, and that there are no obstructions to the airflow is essential to avoid compromising the unit&#8217;s capacity.<\/p>\n<p><strong>General functional check<\/strong>. The inspection must be completed with a comprehensive functional check: calibration of temperature and pressure controls, condition of control components, alarm management, and verification of the correct operating sequence under peak conditions.<\/p>\n<p><strong>Preventive maintenance<\/strong> conducted before summer allows for the identification and resolution of critical issues while there is still time to do so, avoiding emergency interventions during peak production periods.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Preventive maintenance of cooling systems, heat exchangers, dry coolers, evaporative towers, hydraulic circuits, and ventilation systems to avoid system downtime due to the high temperatures during summer.<\/p>\n","protected":false},"author":5,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[81,64,247,61,73,65,470,63,87,472,113,88,710,84],"tags":[4428,3000,803,2294,127,254,3586,486,869,430,1184,3543,138,161,1448,3542,123,1563,3255,356,1543,1881,4570,236,1357],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v20.5 -
