The heart of the system is <strong>Carulite-200<\/strong>, a hopcalite-type catalyst made of manganese dioxide and copper oxide, delivering 99.96% ozone destruction efficiency under proper flow and temperature conditions.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n\n<h2 class=\"wp-block-heading\">When to Use the CDU-15<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The CDU-15 is ideal for <strong>low-flow applications<\/strong> using dry ozone gas, such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Laboratory or pilot-scale ozone systems<\/li>\n\n\n\n<li>Ozone off-gas treatment from generators using dry air or oxygen<\/li>\n\n\n\n<li>Equipment exhaust scrubbing<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">For ambient or <strong>wet gas<\/strong> applications, a model with heating capability, such as the <strong>CDU-30<\/strong>, is recommended.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n\n<h2 class=\"wp-block-heading\">Understanding Gas Conditions: Dry vs. Wet<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Dry Gas<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Sourced directly from ozone generators using oxygen or dry air<\/li>\n\n\n\n<li>Dew point typically -40\u00b0F or lower<\/li>\n\n\n\n<li><strong>Heater not required<\/strong><\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Wet Gas<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Gas containing water vapor or risk of condensation<\/li>\n\n\n\n<li>Often found in ozone off-gas from water systems<\/li>\n\n\n\n<li><strong>Heater required<\/strong> to prevent condensation on catalyst<\/li>\n\n\n\n<li>For high humidity (&gt;30%), consider wet ratings; over 50%, a heater is strongly recommended<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n\n<h2 class=\"wp-block-heading\">Replaceable Catalyst System<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>Carulite-200 catalyst<\/strong> is designed for long life but will degrade over time due to dust, moisture, or chemical exposure. The CDU-15 makes replacement simple:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Remove the top cap<\/li>\n\n\n\n<li>Empty and replace the catalyst material<\/li>\n\n\n\n<li>Reinstall the screen and gasket<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Maintenance time<\/strong>: Less than 30 minutes<br><strong>Complete rebuild kits<\/strong> are available and include replacement screens, gaskets, and fresh catalyst.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently Asked Questions<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">What type of ozone destruct unit do I need?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Consider ozone concentration, humidity, and gas source:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>High concentration<\/strong> (&gt;1 ppm ozone): CDU series<\/li>\n\n\n\n<li><strong>Ambient ozone<\/strong> (&lt;1 ppm): Use units designed for low ozone concentrations<\/li>\n\n\n\n<li><strong>Wet or dry gas<\/strong>: Wet gas requires heating to prevent condensation<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">What is Carulite-200?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Carulite-200 is a catalyst made from manganese dioxide and copper oxide. It efficiently decomposes ozone into oxygen with no consumables and minimal environmental impact.
