IKEUCHI provides a complete system design\u2014including nozzle selection, equipment configuration, and layout planning\u2014tailored to site conditions and dust concentration.<\/p>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">The only utilities required from the customer are water and compressed air.<br \/>\nUnlike conventional water sprinkling, the system avoids surface flooding and mud formation. <span style=\"font-weight:bold;font-size: 1rem\">Compared to electrostatic precipitators, it is significantly more cost-effective<\/span> and easier to install. Most importantly, it drastically reduces off-site dust dispersion.\n<\/p>\n<\/div>\n<div style=\"max-width:824px;margin-left:auto;margin-right:auto\">\n<div style=\"margin-top:5rem;margin-bottom:3rem;width:100%;border-bottom:1px solid #E9E9E9\"><\/div>\n<\/div>\n<p><!-- Benefits Achieved\u3000\u2605\u672c\u6587\u6bb5\u843d\u3068\u7b87\u6761\u66f8\u304d\u3000--><\/p>\n<div style=\"max-width:824px;margin-left:auto;margin-right:auto\">\n<div style=\"margin-bottom:0.8rem;background:url(https:\/\/www.dry-fog.com\/jp\/wp-content\/uploads\/sites\/2\/2024\/10\/10px-45px.svg) no-repeat 0 0;background-size:auto 30px;padding-left: 20px\">\n<h3 style=\"font-size: 1.5rem\">Dust Suppression Principle: IKEUCHI\u2019s Atomization Technology for Effective Dust Control<\/h3>\n<\/div>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">Injecting ultra-fine water droplets in fog form into the air via spray nozzles allows them to gradually descend while dispersing throughout the space. As they fall, the droplets collide with airborne dust particles, capturing them through adhesion. The combined weight causes the dust to settle by gravity\u2014a mechanism known as dust suppression by fog.<\/p>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">Achieving optimal suppression requires matching the droplet size to the size of the dust particles. If the droplets are too large, dust can pass between them without being captured, significantly reducing effectiveness.<\/p>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">IKEUCHI\u2019s proprietary atomization technology utilizes pneumatic spray nozzles to <span style=\"font-weight:bold;font-size: 1rem\">generate water droplets in the 20\u201350 \u03bcm range<\/span>. This precision droplet sizing enables highly efficient dust suppression across various industrial environments.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2025\/07\/nozzle-environ-008-image_02.jpg\" alt=\"\" width=\"820\" class=\"aligncenter size-full wp-image-6304\" \/><\/p>\n<\/div>\n<div style=\"max-width:824px;margin-left:auto;margin-right:auto\">\n<div style=\"margin-top:5rem;margin-bottom:3rem;width:100%;border-bottom:1px solid #E9E9E9\"><\/div>\n<\/div>\n<p><!-- Benefits Achieved\u3000\u2605\u672c\u6587\u6bb5\u843d\u3068\u7b87\u6761\u66f8\u304d\u3000--><\/p>\n<div style=\"max-width:824px;margin-left:auto;margin-right:auto\">\n<div style=\"margin-bottom:0.8rem;background:url(https:\/\/www.dry-fog.com\/jp\/wp-content\/uploads\/sites\/2\/2024\/10\/10px-45px.svg) no-repeat 0 0;background-size:auto 30px;padding-left: 20px\">\n<h3 style=\"font-size: 1.5rem\">Benefits Achieved<\/h3>\n<\/div>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">Deploying the fog-based dust suppression system resulted in rapid and visible improvements.
