The Ruskin Belimo RLH-120 Damper is a top-performing, electrically actuated damper designed for use in HVAC (Heating, Ventilation, and Air Conditioning) systems. This damper, manufactured by Belimo, a global leader in HVAC control solutions, is an essential component for regulating and balancing airflow in commercial and industrial buildings.
The RLH-120 Damper is characterized by its robust design and versatile functionality. It boasts a large, 120 cm (47.24 inches) square frame, making it suitable for larger ductwork applications. Its high airflow capacity ranges from 2700 to 18,000 Nm /h (17,320 to 112,520 CFM), enabling it to effectively manage substantial volumes of air.
The damper operates on an electrical actuation system, allowing for precise control and integration with building automation systems. It features a soft-start function, ensuring a smooth and gradual transition during operation, reducing noise and wear on the damper. The damper also comes equipped with a self-diagnostic function, which can detect and communicate any potential issues, facilitating quick and effective maintenance.
The Ruskin Belimo RLH-120 Damper is constructed using high-quality materials, including a zinc-coated, galvanized steel frame and a polyamide, glass-fiber reinforced polyester (GFRP) blade. These materials provide excellent durability, resistance to corrosion, and a long service life. The damper is also available in various blade configurations, including louvered, perforated, or slot, to accommodate different airflow requirements.
In summary, the Ruskin Belimo RLH-120 Damper is a reliable, high-performing, and versatile solution for regulating and balancing airflow in HVAC systems. Its robust design, large frame size, and advanced features make it an ideal choice for commercial and industrial applications.
