Local tube manufacturer MetaleN manufactures heat exchanger tubes in various steel, copper and nickel alloy inner tubes with copper, steel or aluminium fins. It produces lengths up to 15 m as well as custom fin sizes. ISO 9001 certification ensures controlled processes and consistent quality to EN specification. Premium materials guarantee durable final products.

he company also offers finning of customer- supplied inner tubes. MetaleN serves the petrochemicals, process, drying, refrigeration, mining, farming and energy generation industries. Brass and copper are stocked in sheet and coil, along with industrial-grade copper tube in various dimensions. Coils are slit to customer specifications, including aluminium, with tolerances of ±0.1 mm. Its slitting services support electrical manufacturing, solar, earthmoving, engineering, decorative, electronics and the mining sectors.

MetaleN became independent in 2018 but has operated since 1974 as part of a German group. Its strength lies in providing high-quality tubes with short lead times. Its design-protected spacer tube features an aluminium spacer mounted onto the fins to fill the gap between fin ends and headers, improving both performance and aesthetics. Heat exchanger tubes combine different alloy inner tubes with various fin materials to efficiently heat or cool liquids, gases, oils or air. Material selection depends on ambient and surface temperatures, the type of medium, pressure capabilities, and exchanger size. The most common design – the tube and-shell heat exchanger – is used across process industries.

Compared with plain tubes, finned tubes can halve the number of exchangers required, which significantly reduces electricity and maintenance costs. Further advances include economisers in large boiler systems, which pre-heat water before it enters the boiler, saving energy and improving efficiency. Larger-diameter tubes ensure sufficient water flow through compact economisers. As global energy costs rise, efficient heat exchange is increasingly critical. Capturing waste heat for reuse within plants improves sustainability and reduces overall operating costs.
