Our IP33-65 option noise reduction louver, acoustic shutter and silencer louvre are professionally engineered for outdoor energy storage system containers and industrial power supply equipment cabinets. Combining efficient cross ventilation and reliable noise attenuation performance, these acoustic louvers reach IP65 ingress protection to resist outdoor rain splash and dust infiltration. Available in aluminum and stainless steel material, we support customized dimension, powder coating and OEM branding for global ESS cabinet manufacturers. The built-in sound-absorbing cotton inside silencer louvre effectively reduce cabinet running fan noise while keeping smooth air exchange, widely used in large-scale energy storage, charging pile station and high-low voltage electrical cabinet projects.
