It was, therefore, necessary to provide a solution that did not require any change to the allocated areas for the units;<\/li>\n\n\n\n<li><strong>Plant equalization\/balancing<\/strong>: the system used by the Client involved the use of many condensers in parallel; therefore, it was necessary for the new units to be communicating with each other to maintain a water balance between the basins;<\/li>\n\n\n\n<li><strong>A customised solution for the installation<\/strong>: since the central Chiller plant, where three units are to be installed, is located in the middle of the factory, the Customer required a solution that would enable the already assembled condensers to be moved, as the usual on-site assembly operations would not be possible in this case;<\/li>\n<\/ul>\n<\/div>\n\n<div class=\"wp-block-group alignwide blue_gradient_background is-layout-grid wp-container-core-group-is-layout-8c0afae9 wp-block-group-is-layout-grid\">\n<div class=\"wp-block-group has-custom-css is-layout-constrained wp-block-group-is-layout-constrained wp-custom-css-21a7509c\">\n<h2 class=\"wp-block-heading\">The solution: new evaporative condensers and heat exchangers<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">With the aim of consistently and incisively responding to the identified needs of the Customer, our Technical and Sales Departments \u00ec &#8211; after an in-depth analysis &#8211; selected and proposed the supply of the following units:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>N. 7 <a href=\"https:\/\/cofinair.com\/it\/products\/cfr-a-evaporative-condenser\/\" data-type=\"cofinair_product\" data-id=\"2305\">evaporative condensers CFR-A-140<\/a> series;<\/li>\n\n\n\n<li>N. 3 complete exchange sections for CFR-140;<\/li>\n\n\n\n<li>N.1 complete exchange section for CFR-159;<\/li>\n\n\n\n<li>N.2 complete exchange sections for CFR-184.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The proposed solution was based on Cofinair Decsa&#8217;s <strong>CFR-A series evaporative condensers<\/strong>, which are distinguished by heat exchange coils featuring a higher number of tube rows (24). This design maximises thermal performance while minimising the required installation footprint.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Furthermore, this equipment configuration was able to deliver the thermal capacity required by the Customer while fully complying with the dimensional constraints of the existing plant. At the same time, it addressed the need to upgrade the equipment performance to suit the current local climatic conditions, which differ significantly from those considered in the original plant design more than 20 years ago.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Regarding the complete heat exchange sections, Decsa&#8217;s selection was based on a detailed verification of both the overall dimensions and the available heat transfer surface, ensuring a solution fully equivalent to the original design.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To ensure perfect hydraulic balancing among all units, Decsa also proposed equipping each new evaporative condenser with additional basin equalisation connections. Furthermore, for the four units serving the Clauger refrigeration plant, a special execution was proposed featuring a shared 11 m basin (two units connected together), supplied complete with a common base support structure to facilitate handling and installation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To meet the Customer&#8217;s requirements in terms of durability and ease of maintenance, Decsa also developed the following solutions:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Standardisation of the condenser model across both refrigeration plants, ensuring uniform maintenance procedures and common spare parts.<\/li>\n\n\n\n<li>Installation of a davit arm with manual chain hoist on the top of each tower to facilitate major maintenance operations on the mechanical assemblies.<\/li>\n\n\n\n<li>Enhanced protection of the Z-725 hot-dip galvanised steel panels through the application of DecsaCOATING Plus, a special epoxy powder coating applied in addition to the standard galvanisation.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Finally, to simplify installation activities, Decsa also proposed dedicated lifting base frames, allowing the CFR units serving the Chiller plant to be lifted and positioned fully assembled.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-group has-custom-css is-vertical is-content-justification-center is-layout-flex wp-container-core-group-is-layout-e310e333 wp-block-group-is-layout-flex wp-custom-css-cbcc09dd\"><div class=\"related-element-wrapper post-cofinair_product\">\n    <a href=\"https:\/\/cofinair.com\/products\/cfr-a-evaporative-condenser\/\" class=\"related-element-image-link\">\n        <img decoding=\"async\"\n            src=\"https:\/\/cofinair.com\/wp-content\/uploads\/2026\/03\/CFR-A-evaporative-condenser-884x593-1-e1782814533569-300x200.webp\"\n            alt=\"CFR-A Evaporative Condenser\"\n            class=\"related-element-image\" \/>\n    <\/a>\n    <div class=\"related-element-content\">\n        <h2 class=\"related-element-title\">\n            <a href=\"https:\/\/cofinair.com\/products\/cfr-a-evaporative-condenser\/\">\n                CFR-A Evaporative Condenser            <\/a>\n        <\/h2>\n        <div class=\"related-element-excerpt\">\n                            The CFR-A evaporative condenser is designed for the efficient condensation of refrigerant gases such as ammonia and other industrial refrigerants.\r\nCombining forced air circulation with evaporative heat transfer, the CFR-A evaporative condenser provides high condensation efficiency, reduced operating costs and reliable performance in industrial refrigeration and cold chain applications.
