Utilizing a true catalytic process, this device offers a maintenance-friendly, consumable-free solution for handling ozone in process gas streams.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>What is the CDU-250?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The CDU-250 is a <strong>high-performance ozone destruct device<\/strong> engineered specifically for dry ozone gas flows up to <strong>250 LPM<\/strong>. With all stainless steel internals and no moving parts, this system is designed for longevity and reliability in demanding ozone applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Key features include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Stainless steel construction<\/strong> for superior ozone compatibility.<\/li>\n\n\n\n<li><strong>Reversible flow direction<\/strong> \u2013 no dedicated inlet or outlet.<\/li>\n\n\n\n<li><strong>Vertical mounting<\/strong> required to ensure efficient gas flow and prevent short-circuiting.<\/li>\n\n\n\n<li><strong>Replaceable catalyst media<\/strong> for long-term, cost-effective operation.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Ideal for Dry Off-Gas Applications<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The CDU-250 is optimized for dry air or oxygen applications, typically found in industrial ozone systems where ozone is generated from dry oxygen sources. For these setups, the CDU-250 offers reliable destruction of ozone at high concentrations without the need for heaters or special internal modifications.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">For humid or wet gas streams, the <strong>CDU-300<\/strong>\u2014equipped with a heater\u2014is the preferred choice.<\/p>\n<\/blockquote>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Handling Humidity and Wet Gas<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">While the CDU-250 performs exceptionally with dry gas, <strong>ambient or wet air<\/strong> applications with humidity levels above 30% require different considerations:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>30\u201350% Humidity<\/strong>: Expect reduced flow capacity.<\/li>\n\n\n\n<li><strong>Above 50% Humidity<\/strong>: Use a <strong>heated ozone destruct unit<\/strong> (e.g., CDU-300) to prevent condensation on catalyst media.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Easy Maintenance with Replaceable Catalyst<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Over time, the <strong>Carulite-200 catalyst<\/strong> inside the CDU-250 can become contaminated with impurities such as VOCs, acids, or dust. Fortunately, replacing the catalyst is simple:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Remove the top cap<\/strong> to access the internal screen and gasket.<\/li>\n\n\n\n<li><strong>Pour out old catalyst<\/strong> and replace with fresh media.<\/li>\n\n\n\n<li><strong>Estimated maintenance time<\/strong>: Less than 30 minutes.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A complete <strong>CDU-250 Rebuild Kit<\/strong> is available, which includes new catalyst, screens, and gaskets for quick and efficient servicing.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Understanding Carulite-200 Catalyst<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Carulite-200<\/strong> is a manganese dioxide and copper oxide catalyst used in all CDU-Series destruct units. It\u2019s highly effective and achieves <strong>99.96% destruction efficiency<\/strong> at rated flow. Key considerations include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Safe to handle, though dusty\u2014use appropriate PPE.<\/li>\n\n\n\n<li>Can be <strong>rejuvenated<\/strong> by drying at 500\u00b0F if moisture exposure occurs.<\/li>\n\n\n\n<li>Typically lasts <strong>1\u20133 years<\/strong>, depending on gas purity and humidity.<\/li>\n\n\n\n<li>Non-hazardous and <strong>landfill safe<\/strong> unless contaminated.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Common Questions<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q: Is the CDU-250 right for my application?<\/strong><br><strong>A:<\/strong> Use the CDU-250 if your ozone gas stream is dry (dew point -40\u00b0F or lower) and ozone levels exceed 1 ppm. If your gas contains significant moisture, consider the CDU-300 with heating elements.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q: How often should the catalyst be replaced?<\/strong><br><strong>A:<\/strong> For dry gas: expect multi-year service life. For wet gas: replace annually. Visual inspection and loss in efficiency are indicators.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q: What happens if the catalyst gets wet?<\/strong><br><strong>A:<\/strong> You can dry it in an oven at 500\u00b0F. However, replacing it ensures maximum effectiveness and safety.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Conclusion<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>CDU-250 Ozone Destruct Device<\/strong> is a dependable solution for high-concentration, dry gas ozone destruction. With replaceable catalyst media, stainless steel construction, and a straightforward design, the CDU-250 ensures your ozone processes remain safe, compliant, and efficient.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Need help selecting the right unit?<\/strong><br>Contact Oxidation Technologies for expert guidance and support.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n\n<p class=\"wp-block-paragraph\">You can find this product here: <a href=\"https:\/\/www.oxidationtech.com\/cdu-250.html\" data-type=\"link\" data-id=\"https:\/\/www.oxidationtech.com\/cdu-250.html\">https:\/\/www.oxidationtech.com\/cdu-250.html<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The CDU-250 Ozone Destruct Device is a robust, catalytic ozone destruct unit designed to safely and efficiently convert ozone (O\u2083) into oxygen (O\u2082).
