Many incidents occur when batteries are damaged by strong impact or compression during waste processing, making fire prevention an urgent priority for facility managers.<\/p>\n<div style=\"text-align: center;margin-top:2rem;margin-bottom: 10px\">\n            <img decoding=\"async\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2026\/10\/nozzle-environ-011-image_01.webp\" alt=\"\" width=\"820\" class=\"aligncenter size-full wp-image-6304\" \/>\n        <\/div>\n<\/section>\n<div style=\"margin-top:5rem;margin-bottom:3rem;width:100%;border-bottom:1px solid #E9E9E9\"><\/div>\n<section>\n<h3 style=\"font-size: clamp(20px, 2vw, 30px);padding-left: 14px;margin: 0 auto 2rem;border-left: 5px solid #0c9b6f\">Challenges Faced by the Customer<\/h3>\n<p style=\"margin: 2rem auto 1.5rem;font-size: 1.125rem;line-height:1.6\">Against this backdrop, a plant engineering company contracted by the facility was working urgently to design a water-spray fire protection system using spray nozzles.<\/p>\n<div style=\"text-align: center;margin-top:2rem;margin-bottom: 10px\">\n            <img decoding=\"async\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2026\/10\/nozzle-environ-011-image_02.webp\" alt=\"\" width=\"820\" class=\"aligncenter size-full wp-image-6304\" \/>\n        <\/div>\n<p style=\"margin: 2rem auto 1.5rem;font-size: 1.125rem;line-height:1.6\">The challenge, however, was how to <span style=\"font-weight:bold\">protect the spray nozzles from clogging while the system was on standby<\/span>. In waste treatment environments, dust and particulates are unavoidable, and buildup on the nozzles can cause clogging and impair spray performance.<\/p>\n<p style=\"margin: 2rem auto 1.5rem;font-size: 1.125rem;line-height:1.6\">If the nozzles failed to operate properly in an emergency, the system could fail to perform its intended firefighting function, increasing the risk of fire spread.<\/p>\n<p style=\"margin: 2rem auto 1.5rem;font-size: 1.125rem;line-height:1.6\">As it explored effective preventive maintenance measures, the company consulted IKEUCHI, a manufacturer specializing in industrial spray nozzles.<\/p>\n<div style=\"text-align: center;margin: 50px 0\">\n            <a href=\"https:\/\/www.dry-fog.com\/en\/contact\/\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"background-color: #e67f00;color: #ffffff;font-size: 15px;font-weight: bold;text-decoration: none;padding: 15px 30px;border-radius: 5px\">Contact Us<\/a>\n        <\/div>\n<\/section>\n<div style=\"margin-top:5rem;margin-bottom:3rem;width:100%;border-bottom:1px solid #E9E9E9\"><\/div>\n<section>\n<h3 style=\"font-size: clamp(20px, 2vw, 30px);padding-left: 14px;margin: 0 auto 2rem;border-left: 5px solid #0c9b6f\">Solutions Proposed by IKEUCHI<\/h3>\n<p style=\"margin: 2rem auto 1.5rem;font-size: 1.125rem;line-height:1.6\">IKEUCHI proposed supplying the spray nozzles fitted with specially designed protective caps. The caps help <span style=\"font-weight:bold\">prevent dust and particulates from accumulating on the nozzles<\/span> and causing clogs.<\/p>\n<div style=\"text-align: center;margin-top:2rem;margin-bottom: 10px\">\n            <img decoding=\"async\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2026\/10\/nozzle-environ-011-image_03.webp\" alt=\"\" width=\"820\" class=\"aligncenter size-full wp-image-6304\" \/>\n        <\/div>\n<p style=\"margin: 2rem auto 1.5rem;font-size: 1.125rem;line-height:1.6\">Each cap is fitted securely enough that it will not come off from light contact, but is designed to <span style=\"font-weight:bold\">detach automatically<\/span> when water pressure reaches approximately 0.02 MPa (0.2 bar \/ 2.9 psi). Since the nozzles\u2019 standard spray pressure is 0.3 MPa (3 bar \/ 43.5 psi), the cap detaches well before operating pressure is reached and does not interfere with spraying.<\/p>\n<p style=\"margin: 2rem auto 1.5rem;font-size: 1.125rem;line-height:1.6\">The photos below show the cap before release (left) and immediately after detachment at approximately 0.02 MPa (right).<\/p>\n<div style=\"text-align: center;margin-top:2rem;margin-bottom: 10px\">\n            <img decoding=\"async\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2026\/10\/nozzle-environ-011-image_04.webp\" alt=\"\" width=\"820\" class=\"aligncenter size-full wp-image-6304\" \/>\n        <\/div>\n<p style=\"margin: 2rem auto 1.5rem;font-size: 1.125rem;line-height:1.6\">The caps are made of silicone with <span style=\"font-weight:bold\">heat resistance up to approximately 200 \u00b0C<\/span>, allowing reliable use even in high-temperature environments. This ensures consistent performance without deformation or degradation, even in areas exposed to heat or rapid temperature fluctuations.<\/p>\n<p style=\"margin: 2rem auto 1.5rem;font-size: 1.125rem;line-height:1.6\">The cap is also connected by a wire to a ring attached to the nozzle piping. This keeps the cap hanging near the base of the nozzle after it detaches, eliminating the need to search for it on the floor or around the equipment after spray tests.<\/p>\n<\/section>\n<div style=\"margin-top:5rem;margin-bottom:3rem;width:100%;border-bottom:1px solid #E9E9E9\"><\/div>\n<section>\n<h3 style=\"font-size: clamp(20px, 2vw, 30px);padding-left: 14px;margin: 0 auto 2rem;border-left: 5px solid #0c9b6f\">Benefits Achieved<\/h3>\n<ul style=\"list-style-type: disc;margin-left:2.8rem;font-size: 1.125rem;line-height:2rem\">\n<li style=\"margin:0 auto 0.5rem\">Preventive maintenance of the water-spray fire protection system was strengthened, supporting stable and reliable operation.<\/li>\n<li style=\"margin:0 auto 0.5rem\">The solution can be retrofitted to nozzles already installed in existing facilities, enabling use across a wide range of sites.<\/li>\n<li style=\"margin:0 auto 0.5rem\">Its application has expanded to hazardous-material warehouses and raw-material conveyors.<\/li>\n<li style=\"margin:0 auto 0.5rem\">The protective cap can also be used with nozzles featuring different spray patterns, allowing greater flexibility in system design.<\/li>\n<\/ul>\n<p style=\"margin: 2rem auto 1.5rem;font-size: 1.125rem;line-height:1.6\">IKEUCHI\u2019s spray products continue to help ensure the reliable operation of emergency water-spray systems.<\/p>\n<div style=\"text-align: center;margin: 50px 0\">\n            <a href=\"https:\/\/www.dry-fog.com\/en\/contact\/\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"background-color: #e67f00;color: #ffffff;font-size: 15px;font-weight: bold;text-decoration: none;padding: 15px 30px;border-radius: 5px\">Contact Us<\/a>\n        <\/div>\n<\/section>\n<div style=\"margin-top:5rem;margin-bottom:3rem;width:100%;border-bottom:1px solid #E9E9E9\"><\/div>\n<section>\n<h3 style=\"font-size: clamp(20px, 2vw, 30px);padding-left: 14px;margin: 0 auto 2rem;border-left: 5px solid #0c9b6f\">Water-Spray Nozzle in Action<\/h3>\n<div style=\"max-width:824px;margin-left:auto;margin-right:auto;text-align:center;margin-top:3rem\"><iframe loading=\"lazy\" width=\"100%\" height=\"422\" src=\"https:\/\/www.youtube.com\/embed\/otUXoW_ozec\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\"><\/iframe><\/div>\n<\/section>\n<div style=\"margin-top:5rem;margin-bottom:3rem;width:100%;border-bottom:1px solid #E9E9E9\"><\/div>\n<section>\n<h3 style=\"font-size: clamp(20px, 2vw, 30px);padding-left: 14px;margin-top: 0;margin-bottom: 0.8rem;border-left: 5px solid #0c9b6f;line-height: 1.4\">SDG Contributions<\/h3>\n<p style=\"margin: 0 auto;padding: 0 10px 20px 10px;text-align: left;max-width: 100%;font-size: 1.125rem;line-height: 2.1rem\">Relevant SDG goals for this case.<\/p>\n<div style=\"--col:4;width:100%;max-width:800px;margin:20px auto;overflow:hidden\">\n<div style=\"float:left;width:calc(100% \/ var(--col) - 2%);margin:1%;height:55px;min-width:100px;background-color:#4C9F38;color:#fff;text-align:center;font-size:13px;line-height:1.3;padding-top:12px\">3.
