Unidus Hk Cooperation supplies aluminium L‑finned tubes that are helically wound to maximise surface area for thermal exchange. The fin strips are tension‑wound under controlled deformation, creating a firm contact between fin foot and base tube. The catalogue lists several fin configurations, including “L”, “LL”, “KL”, “G” embedded and extruded types, each with distinct corrosion and temperature capabilities. Reported maximum working temperatures range from 150 °C for the basic L‑type up to 450 °C for the embedded G‑type. Fin materials are aluminium or copper, while tube material is not limited, allowing adaptation to various process fluids.
In the broader market, aluminium finned tubes commonly have outer diameters of 10 mm to 30 mm and wall thicknesses of 1 mm to 2 mm, which are standard dimensions. Typical fin density lies between 30 and 60 fins per metre, providing a balance of pressure drop and heat‑transfer efficiency. Standard lengths are supplied in 1 m to 6 m increments and are packed in timber or metal crates for safe transit. The aluminium alloy generally conforms to EN 573‑3, a typical specification for heat‑exchanger applications. Atmospheric corrosion resistance is described as acceptable for most fin types, while mechanical resistance varies from poor to acceptable depending on the configuration.
These tubes are widely used in air‑coolers, boiler economisers, HVAC units and chemical processing plants where efficient heat removal is critical. Importers should request detailed drawings, fin density and certification of the aluminium alloy before finalising purchase. Confirmation of lead‑time, Incoterms and payment conditions is required directly with Unidus Hk Cooperation, as the listing does not provide these details.
