BSDL-90/BSD-90

Product catalog summary
Overview: The document provides technical specifications and descriptions for ALNOR® ventilation systems, specifically focusing on round ducts and fittings, including segmented bends. ALNOR® is a registered trademark with protected technical patents.
Specifications: The document lists dimensions and weights for various duct sizes, ranging from 200 mm to 1250 mm in diameter, with corresponding lengths and weights. The bending radius is approximately 1.5 times the diameter (D) to minimize pressure loss and flow resistance, with options to increase the radius to 3D or 4D.
Materials: Segmented bends are available in different materials, including galvanized steel, stainless steel (1.4301/304 and 1.4404/316L), aluminum (AW-1050A H24), and copper (M1E z4). Each material has a specific product code format.
Technical Specifications: The document includes flow charts for various bend types (BSDL-90/BSD-90, BPDL-90/BPD-90, BSL-90/BS-90, BPL-90/BP-90/BPL-K-90/BP-K-90, BSKL-90/BSK-90, BPKL-90/BPK-90/BPKFL-90/BPKF-90) showing pressure loss (Dpt) against volumetric flow rate (q) for different dimensions.
Key Features: BSDL bends have sealed inside surfaces and double EPDM gaskets to ensure air tightness class D according to EN 12237 standards, suitable for ventilation and heat recuperation systems.

BSDL-90/BSD-90-1

Long segmented bends Description Segmented bends are designed for spiral coiled ducts. They are made of 5 segments; the bends in diameters of DN 1120 mm and greater are made of 6 segments. The segments are fastened by hemming and seaming. BSDL bends feature sealed inside surfaces of the hemmed seams and double EPDM gaskets to provide air tightness class D according to EN 12237 for ventilation and heat recuperation systems. The bending radius is ca. 1.5D to reduce the pressure loss and the flow resistance along the ventilation system. The bending radius can be increased to 3D or 4D on request to further improve the flow resistance.
