Transcritical booster systems<\/b><\/h5><p data-path-to-node=\"15\">We design systems that efficiently handle both standard refrigeration (NK) and deep-freeze refrigeration (TK) in a single circuit.

Increased Efficiency Through Ejectors and Parallel Compression<\/b><\/h5><p data-path-to-node=\"16\">To ensure that CO2 systems operate with high efficiency even at high outdoor temperatures, we rely on modern technologies such as ejectors (multi-ejector technology) and parallel compressors.

Integrated Heating and Cooling Systems<\/b><\/h5><p data-path-to-node=\"17\">We don&#8217;t view your refrigeration system in isolation.

Our design ensures the highest level of operational safety.  <\/p><p data-path-to-node=\"24\"><b>Is CO2 also effective in the summer?<\/b>  In the past, CO2 was considered inefficient at high outdoor temperatures (&#8220;transcritical operation&#8221;).

Modern CO2 systems operate with high efficiency year-round.  <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-03e534a e-flex e-con-boxed e-con e-parent\" data-id=\"03e534a\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-d0d7576 elementor-widget elementor-widget-html\" data-id=\"d0d7576\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"html.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"custom-cta-block\">\r\n    <div class=\"custom-cta-image-wrapper\">\r\n        <img decoding=\"async\" src=\"http:\/\/coldworld.gmbh\/wp-content\/uploads\/2025\/06\/Dach-1024x768.jpg\" alt=\"A technician talking on the roof, surrounded by new piping for the integration of a spiral freezer into an existing NH\u2083 deep-freeze system.\">\r\n    <\/div>\r\n\r\n    <div class=\"custom-cta-content\">\r\n        <h1 class=\"custom-cta-title\">Schedule an Initial Consultation<\/h1>\r\n        \r\n        <div class=\"custom-cta-description\">\r\n  Are you looking to install an energy-efficient refrigeration system or optimize your existing system?<br>Schedule a free initial consultation now.\r\n        <\/div>\r\n        \r\n        <a href=\"https:\/\/www.coldworld.gmbh\/en\/contact-us\/\" class=\"custom-cta-button\">Get in touch<\/a>\r\n    <\/div>\r\n<\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>CO2 Refrigeration Systems (R744) Climate-Neutral Cooling &#038; Heating [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":7157,"parent":10138,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"inspiro_page_layout":"narrow","inspiro_hide_title":false,"footnotes":""},"class_list":["post-10088","page","type-page","status-publish","has-post-thumbnail","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.4 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>CO2 Systems - cold.world engineering<\/title>\n<meta name=\"description\" content=\"Design of energy-efficient CO2 refrigeration systems (R744).
