The LBC Double-Layer Louver is a ventilation and airflow regulation device specifically designed for industrial environments, such as power plants, and boasts a range of superior performance characteristics. A detailed description follows below:
- Materials and Structure: Constructed from high-strength aluminum alloy profiles, the components undergo an aging and anodizing treatment. Their mechanical properties meet international standards, offering an elegant finish and exceptional corrosion resistance. Furthermore, the surface can be treated with a powder-coating finish—customized to user specifications—to further enhance its resistance to corrosion. The double-layer louver assembly consists of rain-proof blades equipped with integrated water-collection channels, side frames featuring drip-edge profiles, and streamlined adjustable blades.
- Adjustment Functionality: Adjustment mechanisms are available in two variants: manual and electric. The electric version utilizes high-quality imported actuator components to ensure smooth, reliable, and noise-free operation. Personnel can flexibly adjust the louver’s opening angle based on indoor temperature or specific ventilation requirements. With a wide range of adjustable angles, the system effectively meets diverse ventilation and natural lighting needs.
- Performance Features: The system offers excellent rain and wind resistance; even during heavy downpours, it effectively prevents rainwater from penetrating the interior, ensuring that no “water curtain” forms on the windward side. Additionally, it features superior sealing capabilities, providing thermal insulation, regulating airflow, and performing dust-capture and collection functions—thereby offering a reliable ventilation solution for regions prone to heavy wind and sand.
- Scope of Application: Widely applicable across various sectors—including power generation, metallurgy, and chemical processing plants—as well as sports stadiums, theaters, and other large-scale architectural structures, serving the purposes of rain protection, ventilation, and airflow regulation.
- Specifications and Dimensions: The LBC Double-Layer Louver features an overall thickness of 160 mm. It can also be configured as a single-layer rain-proof unit or a single-layer adjustable unit, with overall thicknesses of 90 mm and 100 mm, respectively. The frame profiles have a thickness of 1.2 mm, while the blades are 1.1 mm thick. Custom sizing is available upon request.
